Early Communication

“Marine Telegraph. Through the exertions of Mr. Jackson, Post Master, we are at length likely to have a marine telegraph erected on ‘Telegraph Hill,’ a knoll just back of Diamond Head and a little to westward of the government road to Waialae. A sum sufficient to defray the cost attending its erection and for keeping it in operation for some months has been subscribed.”

“So much has been said about the supposed value of a telegraph, that we are glad the experiment is to receive a fair trial. The telegraph will consist of a pole (seventy) feet in height, to have four arms, each four feet long.”

“From this knoll vessels can be seen in a clear day from twenty to twenty-five miles either way from Diamond Head, and all coasters as well as foreign vessels will be reported by it.”

“One advantage will be that China bound vessels, passing during the day time can be reported, and probably in most cases can be boarded from the port, to procure news, where heretofore they have passed without stopping.”  (Pacific Commercial Advertiser, June 4, 1857)

On June 12, 1857, a marine telegraph was put into operation behind Diamond Head.  A companion semaphore signal was put on Honolulu Hale on Merchant Street in downtown Honolulu.

This device was actually a kind of semaphore designed to send visual (rather than electric) signals to the post office in Honolulu Hale when an approaching ship was sighted. (Schmitt)

The ‘marine telegraph’ is a semaphore.  Initially set up by the local Post Master to time the landing of ships to collect the mail, it also served as a means to notify the community of what ship was landing, especially those who service the ships and their passengers.

“There were very few who could not read the signals made by the directions of the arms of the semaphore and as soon as any was made some one would call out “whale ship coming past Koko Head” or “Fore and after coming past Barber's Point” or “Steamer coming past Koko Head” as the case might be.”  (Pacific Commercial Advertiser, May 21, 1905)

The postmaster posted advertisements in the newspapers offering to sell “Marine Telegraph Cards of Signals” for $1.

“Back of the head (Lēʻahi, Diamond Head) there was a lookout and when he saw a ship coming he raised a flag. Directly I saw it I gave the cry ‘Sail, ho!’ - and up went the signal on the semaphore. It was my call that brought the people from the neighboring offices and the signal from those further away.”

“If it turned out to be a whaler, all was well; but if it happened to be a schooner from the other islands I came in for a drubbing of words from everybody within the limits of civilization. I as the small boy who was blamed for the error of the lookout and seldom praised for his correct reports.”  (Stacker; Sunday Advertiser, December 5, 1909)

“Naturally there was a good deal of rivalry among the pilots, for in those days and for years, they received their compensation by the way of fees. Each man was supposed to leave the pilot house when a signal was given and go out to meet the vessel. The first man out got the ship and the fee.”

“If there were more coming down the channel Signal No. 2 would show it.” (Stacker; Sunday Advertiser, December 5, 1909)

“This enterprise, which has now been conducted for some two years, has proved itself of so much public benefit that there is scarcely a man in the community who would not regret to see it discontinued.” (Pacific Commercial Advertiser, November 17, 1859)

Unfortunately, a storm in 1872 took the semaphore out of service.  The loss was felt … “That the telegraph is needed and must be put in order again, everyone will concede; but the question is, whose duty is it to see the thing done.”   (Pacific Commercial Advertiser, January 27, 1872)

The Chamber of Commerce met shortly thereafter.  “It was the general understanding that the telegraph must be resumed, and a committee was appointed to procure subscriptions and attend to the necessary details.”  (Pacific Commercial Advertiser, February 17, 1872)

“When the telephone system got into working order the lookout station was moved to a position on Diamond Head which gave a view further along the channel, because it was no longer necessary for the station to be in full view of the city.” (Hawaiian Star, February 10, 1899)

In 1878 Samuel G Wilder established the first telephone line on Oʻahu, from his government office to his lumber business.  “By the fall of 1881 telephone instruments and electric bells were in place in the Palace.”  (The Pacific Commercial, September 24, 1881)   (Charles Dickey in Haiku, Maui had the first phones in the islands (1878;) connecting his home to his store.)

Diamond Head was connected by telephone with the book store of Whitney & Robertson conducted in Honolulu Hale.  (Evening Bulletin, September 27, 1907)  The Marine Telegraph semaphore system was later discontinued.

Right about this same time, Hawaiʻi was getting connected through a submarine telegraph cable.  The first submarine cable across the Pacific was completed (landing in Waikīkī at Sans Souci Beach) linking the US mainland to Hawaiʻi, Canada, Australia, New Zealand and Fiji (1902) and Guam to the Philippines in 1903.  (The first Atlantic submarine cable, connecting Europe with the USA, was completed in 1866.)

The first telegraph message carried on the system was sent from Hawaiʻi and received by President Teddy Roosevelt on January 2, 1903 (that day was declared “Cable Day in Hawaiʻi.”)  On January 3, 1903, the first news dispatches were sent over the Pacific cable to Hawaiʻi by the Associated Press.

On the afternoon of July 4, 1903, Honolulu was connected to the Pacific cable from Midway Island, which extended east to the Philippines and China. On that day, the Pacific cable commenced full operation between Asia and Washington, DC.

Pālolo Hill

“And they gathered their friends together and journeyed up into the hill country, and when they did not return others followed, saying unto them - 'Why, therefore, do ye choose to dwell in the hill country?'“

“And they answered, 'For it is here we obtain the freedom of the air, with all its freshness and purity; it is here we get strength for the mind and body, and it is here we enjoy the breath of life.'“  (Evening Bulletin, October 21, 1911)

So went the marketing for the Pālolo Hill development - the Homeland of Health - above Kaimuki.

The announcement of the project a year before carried the same positive enthusiasm, “Pālolo Hill may not only be destined to blossom as the rose, but it will be dotted with a thousand homes, the place of residence of delighted sojourners who seek the many incomparable advantages offered by climatic conditions only to be found in the Paradise of the Pacific, but Honolulu in particular.”

“The Kaimuki Land Company has completed all arrangements for setting a large force of men at work in the grading of fifty foot streets and plotting some twelve hundred lots in this sightly tract of land located at the terminus of the Hotel street and Waiʻalae car-line.”

“Pālolo Hill, commanding a magnificent view of the Pacific Ocean, the frowning slopes of Diamond Head, and the bald prominence of Koko Head, will be transformed into a place of much activity before the close of the old year.”

“The plans as outlined by the land company are elaborate in the extreme. The first of the week will find teams and graders at work on the roads. ... (The central) avenue will serve as a feeder for the curved and winding highways that weave their way in and around the brow of this eminence.”

“It is claimed, that there is not a lot in the entire twelve hundred that is of lower elevation than three hundred feet. The highest elevation recorded in the tract is eleven hundred feet. A visit to the tract, where grading operations have already begun, would show that there is no portion of the district that has an unobstructed marine view. (Evening Bulletin, December 9, 1910)

Some background ... William Lunalilo ended up with most of the area known as Kaimuki through the Great Māhele (1848.)  Lunalilo was born on January 31, 1835 to High Chiefess Miriam ‘Auhea Kekauluohi (Kuhina Nui, or Premier of the Hawaiian Kingdom and niece of Kamehameha I) and High Chief Charles Kanaʻina.

When Kamehameha V died on December 11, 1872 he had not named a successor to the throne.   The Islands' first election to determine who would be King was held - Lunalilo defeated Prince David Kalākaua (the Legislature met, as required by law, in the Courthouse to cast their official ballots of election of the next King.  Lunalilo received all thirty-seven votes.)

Lunalilo was the first of the large landholding aliʻi to create a charitable trust for the benefit of his people.  He was to reign for one year and twenty-five days, succumbing to pulmonary tuberculosis on February 3, 1874.

His estate included large landholdings on the five major islands, consisting of 33-ahupuaʻa, nine ʻili and more than a dozen home lots. His will, written in 1871, established a perpetual trust under the administration of three trustees to be appointed by the justices of the Hawaiian Supreme Court.

His will instructed his trustees to build a home to accommodate the poor, destitute and infirm people of Hawaiian (aboriginal) blood or extraction, with preference given to older people. The will instructed the Trustees to sell all of the estate’s land to build and maintain the home.    (Supreme Court Records)

In 1884, the Kaimuki land was auctioned off. The rocky terrain held little value to its new owner, Dr. Trousseau, who was a “physician to the court of King Kalākaua”.  Trousseau ended up giving his land to Senator Paul Isenberg.  Theodore Lansing and AV Gear later bought the Kaimuki land (in 1898.) (Lee)

Gear, Lansing & Co, one of Honolulu's first real estate firms, envisioned Kaimuki becoming a high-class residential area, but was stymied by buyers' lack of interest.

Later Charlie Stanton, FE Steere and Frank E Thompson formed the Kaimuki Land Company and took over the Kaimuki tracts. Eventually, they turned it over to Waterhouse Trust Company who sold the land for eight cents a square foot and nine cents for corner lots. (Takasaki)

(There appear to be some interchangeable names of the development  entity: Kaimuki Land Company, Pālolo Land Company and Pālolo Land and Improvement Co.)

The Pālolo Land Company is an organization composed of several gentlemen who own upper Pālolo Valley and the scenic portion of Pālolo Hill it overlooks Kaimuki, and from Upper Pālolo Hill half of Oʻahu Island may be seen. Splendid roads have recently been constructed.  (Mid-Pacific Magazine)

Not familiar with the Pālolo Hill subdivision name?

It’s not clear if any official name change took place, but we now typically refer to this area as “Wilhelmina Rise” and Maunalani Heights.  (Some incorrectly say it was developed by Matson in the 1930s; the above notes it was built 20-years before and by local real estate developers.)

However, “The streets are ... named after the steamers that make regular calls at the port of Honolulu.  Wilhelmina Rise is a broad and absolutely straight thoroughfare extending for a mile and a half up the slope of Pālolo Hill.”  (Evening Bulletin, December 9, 1910)

Up Pālolo Hill (Wilhelmina Rise,) you'll find Lurline, Matsonia, Maunalani, Mana, Sierra, Wilhelmina, and Claudine, Matson liners and freighters.

The image shows a drawing of the new Pālolo Hill development (Mid-Pacific Magazine, 1912.)    In addition, I have included more related images in a folder of like name in the Photos section on my Facebook and Google+ pages.

Diamond Head Charlie

“Ste-e-e-mer off Koko Head!”  (PCA, 1906)

“Before the telephone was invented, and long before the system was in use in Honolulu, we had the lookout station on Telegraph Hill, which by means of a semaphore arrangement communicated with a station on the building (downtown.)”

“Every merchant was supplied with the code, and whenever a schooner, a steamer, a mail packet, or a man of war, was sighted, the heart of the town knew it immediately.”  (Hawaiian Star, February 10, 1899)

Pu‘u O Kaimukī (aka “Kaimukī Hill”) was used as a sighting and signal station (using semaphore technology,) giving it the name “telegraph hill.”   It had broad view over the Pacific and line-of-sight to downtown Honolulu.  Back then, they used this vantage point to spot ships coming in, and then conveyed the news to Honolulu.

This is where John Charles Pedersen was first stationed.  Petersen was appointed lookout … by the then Minister of the Interior, Samuel G Wilder. The station was located at the top of Kaimuki Hill. (Evening Bulletin, September 27, 1907)

Semaphore towers used arms and blades/paddles to convey messages; messages were conveyed/decoded based on the fixed positions of these arms.  Reportedly, in 1857, a semaphore mechanism on Puʻu O Kaimukī, with large moveable arms, was attached to the top of a sixty-foot pole and used to signal to Honolulu.

The official receiving station from Kaimukī was on Merchant Street, but some have suggested other receiving stations at Kaʻahumanu Street and the foot of Nuʻuanu.

“When the telephone system got into working order the lookout station was moved to a position on Diamond Head which gave a view further along the channel, because it was no longer necessary for the station to be in full view of the city.” (Hawaiian Star, February 10, 1899)

Diamond Head was connected by telephone with the book store of Whitney & Robertson conducted in Honolulu Hale.  (Evening Bulletin, September 27, 1907)

Petersen’s regular weather reports (telephoned every evening promptly at 10 o’clock,) “Diamond Head – 10 pm – weather, hazy; wind, fresh, NE,” or calls with a ship sighting, “Ste-e-e-mer off Koko Head!” “gladdens the hearts of thousands of people every week.”  (Pacific Commercial Advertiser, January 29, 1906)

Following the call, HECO’s whistle would scream three long blasts, loud enough for all Honolulu to hear. This meant the ship would arrive in two hours, and people rushed to the harbor.

“All hands, including government officials of many grades and various departments, agents' representatives, post office clerks, hotel and newspaper men, waterfronters, hackmen, messengers, shipping men, storekeepers, the large army of people "expecting friends," and frequently Captain Berger and the Hawaiian Band, make haste to get down to the dock to ‘see the steamer come in.’” (Pacific Commercial Advertiser, January 29, 1906)

“For many years all Honolulu has depended on one man to announce the sighting of mail and freight steamers as well as the fleet of ‘windjammers.’  … ‘John Chas. Peterson, Keeper Diamond Head Signal Station,’ as he is designated in the directory.”  (Pacific Commercial Advertiser, January 29, 1906)

He was better known as Diamond Head Charlie.

Petersen was born in Gothenburg, Sweden. He came to the Islands eighteen years ago from San Francisco in the old schooner Lizzie Wight.   He left for a short while, returned and married a Hawaiian who died four months after her child was born. “The pledge of their union still lives to cheer the father's heart.”

“His house is built on a rough slope of Diamond Head, facing the sea and from its position the faithful lookout commands an almost unlimited view of the broad Pacific. His business is to watch for incoming vessels and report them. … He watches with unfailing zeal, and it is very seldom that a vessel ever escapes his sharp eyes.”  (Pacific Commercial Advertiser, December 19, 1894)

“The great landmark on which he passes his time is well known to tourists and others, and it is eagerly watched for from the decks of incoming steamers. With the aid of glasses passengers can detect a small cottage, painted white, which is built on the side of the bleak extinct volcano.”

“Their home consists of bedrooms, a tiny bit of a pantry, and an observation room, from which Peterson scans the sea. On one side a large water tank stands, encased in wood; they must store the rain water or else go as far as James Campbell's for the fluid.”

“In front of the cottage stands a flagpole eighty feet high, which is used for signaling. In a locker "Charlie" has a full complement of flags, and is proud of his belonging.”

“A large telescope stands in the observation room, which aids the eye to see a distance of at least thirty miles.  It is a powerful glass and when a vessel is eight miles away she does not appear to be more than 1000 yards distant. This telescope was presented to the lookout by Wm. G. Irwin and other merchants about town.”

“Peterson is on duty about seventeen hours every day, and divides his time between watching for vessels and cooking his meals. He has no servants, and of course must prepare his own food, which is done under great difficulties at times, as he has no kitchen.”

“He comes to town but once a month for his pay. While he is absent from his post, which is taken for the time being by a native, he usually purchases enough supplies to last him a month. His salary at present is $75 a month. He started in sixteen years ago at $50, and after a year's time the sum was increased to $60.  He worked for twelve years for the last mentioned sum.”  (Pacific Commercial Advertiser, December 19, 1894)

“His glory began to grow dim when the lighthouse was erected at the Head and a keeper came to divide honors with him. Though he has constantly been an important factor to the business community and reported the ships appearing off the port, he became less a household word after the installation of the trans-Pacific cable.”    (Evening Bulletin, September 27, 1907)

“Each year since 1895 General Soper has made a Christmas collection for Charlie among the business men of the town. The largest sum was $440 collected in 1902. Charlie was a faithful man and the news of his death (September 27, 1907) caused widespread expressions of regret throughout the town.  (Evening Bulletin, September 27, 1907)

“For several weeks past Peterson was in the hospital and little hope was held for his recovery.  Close on the allotted three score years and ten, he now sighted that mysterious bark whose captain is called Death.”  (Pacific Commercial Advertiser, September 28, 1907)

The image shows Diamond Head Charlie and his telescope outside his house. (Pacific Commercial Advertiser, January 29, 1906)  In addition, I have added others similar images in a folder of like name in the Photos section on my Facebook and Google+ pages.

Aliʻiolani College

The school seemed to change names, and locations; but, for the most part, it was run by the same person, Leopold Gilbert Blackman.

Born on July 4, 1874 in Cheltenham, England, Blackman was the son of Thomas and Harriet (Sutherland) Blackman. He was an associate of Saint Nicholas College, Lancing, England, and was principal of the preparatory school of Ardingly College before coming to Hawaiʻi. (Builders of Hawaiʻi)

At the request of the Bishop Willis, Blackman arrived in the Islands in 1900 to take charge of ʻIolani School.  He served as head of school at ʻIolani for one year; then, he was an assistant at Bishop Museum 1901-09 (also serving as editor of the Hawaiian Forester and Agriculturist.)

Then, he went back to school.

It started with Aliʻiolani College, in Pālolo.  “Aliʻiolani College was an offshoot from the ʻIolani (school.)”  (Thrum)

“Aliʻiolani College, started a few years ago in a cottage, has now quite arrived as a respectable acquisition to Honolulu's fine array of public and private schools. It appears to supply a distinct want for its neighborhood, besides aiding to solve the problem of school congestion for the city.”  (Hawaiian Star, June 21, 1910)

“(T)hrough the generosity of Mrs Mary E Foster, foundress of the college, permanent buildings had been erected sufficient for all present needs and in many other ways progress had been made toward making Aliʻiolani an efficient unit of the splendid Honolulu family of educational institutions.” (Hawaiian Star, June 21, 1910)

(Daughter of James Robinson, Mary Robinson married Thomas Foster, an initial organizer of the Inter-Island Steam Navigation Company.  That company founded a subsidiary, Inter-Island Airways, that later changed its name to Hawaiian Airlines.  Their home later became Foster Botanical Garden.)

“Among our many well equipped establishments we believe that Aliʻiolani has a definite destiny as a boys' boarding school, offering at moderate fees a substantial education soundly based upon the elementary branches of Instruction, an education in which habits of discipline cheerful obedience to constituted authority, courtesy and loyalty are given a recognized place as adjuncts to true manhood.”  (Blackman, Hawaiian Star, June 21, 1910)

However, that school on that site had a short stay.

The building and grounds of the Aliʻiolani College was offered to the board of education “for the establishment of vocational schools … rent free for four months or until the legislature provides ways and means for maintaining the schools.”

“The offer of Aliʻiolani has been made by the owner, Mrs. Nellie E. Foster, who has also offered to contribute generously towards a fund to meet running expenses.”    (Hawaiian Gazette, May 24, 1912)

A Department of Education Biennial Report for 1912 notes Blackman as principal of the Honolulu School For Boys, it was divided into three departments: Preparatory, Grammar School and High School.  “The Honolulu School for Boys, at Kaimukī, (was) an independent boarding and training school, originally the Aliʻiolani College.”  (Thrum)

“The campus comprises eighteen acres and is situated in the salubrious Ocean View district of Honolulu. Extensive views of mountain range and ocean are obtained, while continual trade breezes temper the air and render residence at the school pleasant and healthful.”

“The main building consists of a two-story edifice with two one-story wings. The ground floor is devoted chiefly to class rooms and dormitories. Of the wings, one furnishes a dining hall; the other, the matron's residence, is chiefly devoted to the use of the smaller boys. All dormitories are upstairs, are well ventilated and lighted and open upon spacious lanais.”

“The increasing enrollments of the school necessitated an additional building to be erected in the summer of 1912, known as the Grammar School. This new structure is of two stories—the upper one being devoted to dormitory accommodations and the lower one to class rooms.”  (DOE, 1912)

The school later moved into lower Kaimukī, and, again, changed its name – and the old campus was converted to a hotel.

“For some time the place (former Aliʻiolani campus in Pālolo) remained vacant but recently was run as a boarding house until take over by King, who has renovated the building and started a modern hotel.  It has been renovated, remodeled and improved and will be known as Aliʻiolani Hotel.” (Honolulu Star-bulletin, September 19, 1916)

Honolulu School for Boys changed its name to Honolulu Military Academy.  (Thrum, 1917)  “It was controlled by a board of 10 trustees of which the president (Blackman) was a member and presiding officer ex officio.”

“It had no endowment, but owned a fine piece of property consisting of grounds and six buildings … at Kaimukī near Waiʻalae Bay, a mile from the end of the Waiʻalae street-car line.”    (DOI Bureau of Education Bulletin 1920)

“The school drew its cadets from all points in the islands. The 1918-19 roster showed 64 from Honolulu, 10 from Oʻahu outside of Honolulu, 16 from Hawaiʻi, 11 from Maui, 10 from Kauaʻi, 1 from Molokai, 2 from California, and 1 each from New York State, Minnesota, and Japan.”

“It began at first with instruction only in the elementary grades; but it grew to offer a 12-grade program of studies.” (DOI Bureau of Education Bulletin 1920)

Then, in January 1925, Punahou School bought the Honolulu Military Academy property - it had about 90-acres of land and a half-dozen buildings on the back side of Diamond Head.

It served as the “Punahou Farm” to carry on the school’s work and courses in agriculture.  “We were picked up and taken to the Punahou Farm School, which was also the boarding school for boys. The girls boarded at Castle Hall on campus.”  (Kneubuhl, Punahou)  The farm school was in Kaimukī between 18th and 22nd Avenues.

In addition to offices and living quarters, the Farm School supplied Punahou with most of its food supplies.  The compound included a big pasture for milk cows, a large vegetable garden, pigs, chickens, beehives, and sorghum and alfalfa fields that provided feed for the cows. Hired hands who tended the farm pasteurized the milk in a small dairy, bottled the honey and crated the eggs.  (Kneubuhl, Punahou)

The Punahou dairy herd was cared for by the students as part of their course of studies - the boys boarded there.  However, disciplinary troubles, enrollment concerns (not enough boys signing up for agricultural classes) and financial deficits led to its closure in 1929.

By the mid-1930s, the property was generally idle except for some Punahou faculty housing.  In 1939, Punahou sold the property to the government as a site for a public school (it's now the site of Kaimuki Middle School.)  The initial Aliʻiolani College site is the present site of Aliʻiolani Elementary School.)  

The image shows the original Aliʻiolani building, funded by Mary Foster (Maui News, July 30, 1910.)   In addition, I have added other related images in a folder of like name in the Photos section on my Facebook and Google+ pages.

Pu‘u O Kaimukī - Telegraph Hill

When King Kamehameha stationed his troops on the beaches of Waikīkī in preparation for the battle to take O‘ahu, he stationed lookouts at Pu‘u O Kaimukī (aka "Kaimukī Hill") to spot enemies arriving by sea.

When Honolulu became a major port, "Kaimukī Hill" was used as a signal station (using semaphore technology,) giving it the name “telegraph hill.”   It had broad view over the Pacific and line-of-sight to downtown Honolulu.  Back then, they used this vantage point to spot ships coming in, and then conveyed the news to Honolulu.

Optical “telegraphs” or signaling devices have been traced back to ancient times (initially using torches) and were the fastest systems to convey messages over long distances; these “telegraphs” eventually moved toward semaphore towers.

If Internet and its communications channels are at the forefront of the signaling opportunities of the 21st century, the semaphore was the signals intelligence breakthrough at the time of Napoleon (and Washington and Kamehameha.)

Semaphore towers used arms and blades/paddles to convey messages; messages were conveyed/decoded based on the fixed positions of these arms.

During the Napoleonic Wars, the French revolutionized land-based communications with the construction of semaphore towers bearing rotating arms to fashion coded signals.  The British quickly followed suit in that new era of signals intelligence.

The semaphore tower/semaphore line design was first thought up by Robert Hooke in 1684 and submitted to the Royal Society. The system was not implemented, though, due to military concerns.

However, this did lead to Claude Chappe developing the first visual telegraph in 1792 - eventually covering much of France via 556 stations. In France, this was the primary source of communication for military and national applications, until it became more widely used in the 1850s.

In Hawaiʻi, Kaimukī Hill had been used as a semaphore signal station ever since Fair Haven (Honolulu Harbor) became prominent in Hawaiian commerce.  This semaphore station reported all incoming ships from Koko Head to Barber’s Point.

“Before the telephone was invented, and long before the system was in use in Honolulu, we had the lookout station on Telegraph Hill, which by means of a semaphore arrangement communicated with a station on the building (downtown.)  Every merchant was supplied with the code, and whenever a schooner, a steamer, a mail packet, or a man of war, was sighted, the heart of the town knew it immediately.”  (Hawaiian Star, February 10, 1899)

“From Telegraph Hill and the slopes toward Waiʻalae may be seen Koko Head, the beautiful expanse of ocean and on clear days the distant islands of Molokai, Lanai, and Maui. On the town side, the residents look over the town, across the cane fields to the Waianae range.”  (Evening Bulletin, September 26, 1898)

“Mauka of Diamond Head, for a distance of three or four miles is a high ridge that vernacular geologists call a "hog back." At the most elevated point on this ridge is the debris of Telegraph Hill (Kaimuki). In the olden days vessels coming from the north were signalled to the city from Kaimuki by a semaphore system, clear and effective. The town end of the line was a building on Kaahumanu street, then occupied as a sail loft.”  (Hawaiian Gazette, January 13, 1899)

Reportedly, in 1857, a semaphore mechanism on Puʻu O Kaimukī, with large moveable arms, was attached to the top of a sixty-foot pole and used to signal to Honolulu.

The official receiving station from Kaimukī was on Merchant Street, but some have suggested other receiving stations at Kaʻahumanu Street and the foot of Nuʻuanu.

Upon receiving the message, a signal was broadcast to the town noting the names and ports of origin of each ship coming into view.  This information was announced in Honolulu by loud proclamation and bell ringing, and preparation made to tow the vessel in by hand or bullock power.

In 1866, the roof of Honolulu Hale on Merchant Street was fitted with a new marine lookout with a taller semaphore, making its signals accessible to a larger segment of the population.

This optical telegraph system was an important tool for residents of Honolulu.  The signals were unique and people became familiar with them, so most could decode the signal and know which ships were coming.

Likewise, besides alerting the postmaster to the imminent arrival of the mail, it was helpful to merchants expecting new goods and people awaiting friends and relatives.

Semaphore was then called "marine telegraph", and it seems logical that the early map-makers of Hawaiʻi would name the hill "Telegraph Hill."

"When the telephone system got into working order the lookout station was moved to a position on Diamond Head which gave a view further along the channel, because it was no longer necessary for the station to be in full view of the city.” (Hawaiian Star, February 10, 1899)

Puʻu O Kaimukī had several colloquial names; one was Christmas Tree Park. There’s a bare metal Christmas-Tree-looking pole.  It’s not a remnant of the prior semaphore communications, it’s just a Christmas tree, built by the City and County soon after the park’s christening in 1991. Every year since then the big metal tree gets hung with Christmas lights.

It’s also referred to as Reservoir Park, a reminder of the days in the early 1900s when the top of the hill housed a water storage tank for the Honolulu Water Works. Another name is Bunker Hill, from the World War II era when the spot became a handy surveillance bunker for the military.

It’s known today as Puʻu o Kaimukī Park and is just behind (makai) the Kaimukī Fire Station.

On November 13, 1900, the first Marconi wireless telegraph system was set up and messages were sent and received between Oʻahu and Molokaʻi across a twenty-eight mile channel.  Military semaphore flag signals are still used, today
