Repairs to quarters, tower, and apparatus at many stations have been made as given in more detail below.

The lights of Cebu Harbor were thoroughly overhauled and repairs made, including the construction of keeper's cottages at Mactan Island and Bagacay Point. Wooden towers and keeper's cottages were built at Legaspi and Escarseo Point, Mindoro. The light at Sangley Point, Cavite, was elevated and keeper's cottage built.

The light-house depot, containing a chaotic mass of ironwork for towers and dwellings, new and old illuminating apparatus, tools, and supplies, has been overhauled; the ironwork assorted, cleaned, and painted by the depot force, and a systematic method of receiving and issuing stores inaugurated.

Among the property found on hand are the following: One iron tower and apparatus for Capitancillo Islet, one iron tower for Bajo Apo Islet, one set of illuminating apparatus for Jintotolo Island, parts of two or three sixth-order iron towers, parts of lantern for Jintotolo.

The illuminating apparatus found on hand was placed in Bugui Point tower, that station being ready for it and the transfer being found to be feasible without deranging the general system of coast illumination of the Archipelago.

The metal work has been used as required, and the towers have been repaired as far as is practicable before their erection is undertaken.

From an inspection of the Spanish records the ironwork for a tower was located as probably on Tanguingui Island, and a visit by the tender revealed that this ironwork had been landed there and the construction of a light station begun. This ironwork is to be cared for as soon as a working party is established at Capitancillo Islet, in the vicinity.

In the office the Spanish light-house records have been examined and the documents and plans relating to engineering work classified and placed in suitable file cases for preservation and reference. The other documents, relating to administration, have been returned to the bureau of archives.

The plan for the general illumination of the Archipelago has been revised and corrected.

NEW LIGHTS.

The following-named lights were established during the fiscal year:

Bugui Point, Masbate Island.-A third-order flashing light red and white; December 1, 1902.

CHANGES IN LIGHTS.

During the fiscal year the following changes were made in existing lights: Sangley Point, Manila Bay, Luzon Island.-Height of light increased 9 feet. Catbalogan, west coast of Samar Island.—Changed from a lantern to a 9-mile port light. San Pedro, Cebu Harbor.-Changed from an old-style large lantern to a 9-mile port light; March 28, 1903.

San Nicolas, Cebu Harbor.-Changed from an old-style large lantern to a 9-mile port light; March 27, 1903.

Zamboanga, Mindanao Island, end of mole at Zamboanga.-Changed from a lantern to a 9-mile port light.

CONSTRUCTION.

During the fiscal year the following new construction was accomplished:

1. Corregidor Island, Manila Bay. Three frame buildings for quarters and kitchens were erected and a fence built around the grounds.

2. Bugui Point, Masbate Island.-A working party landed about November 1, 1902. A substantial stone dwelling has been built for the keepers and is nearing comple

tion; the kitchen and storerooms in separate building and the tower were completed. New apparatus was placed in the tower and the light put in operation December 1, 1902.

3. Jintotolo Island, off southwest point of Masbate Island.-The masonry of the tower has been completed and the lantern as far as material on hand permits. The new apparatus and the parts required to complete the lantern were ordered from Paris in October, 1902, and in February, 1903, and are expected within a few weeks. The stone dwelling and outhouse are almost completed and the station nearly ready for occupancy. A temporary lantern is exhibited now and cared for by a single keeper. 4. Capul Island, near north end of island.—A working party landed here about the end of January, 1903. Difficulties with overseers and workmen have delayed the work, but a limekiln has been built, furnishing all the lime needed for the work, and the masonry of the dwelling is progressing. The roof has been framed and can be quickly put on when the masonry is finished. A temporary fixed light, sixth order, is in operation here.

New apparatus for a third-order flashing light at this station and material to repair the lantern (damaged by insurrectos) was ordered from Paris, November 19, 1902. It is proposed to use a modern petroleum vapor lamp at this station. The station should be completed by September 1, 1903.

5. San Bernardino, on summit of islet in San Bernardino Straits.-A working party landed here May, 1903, about as early in the season as is possible with the sea and wind prevailing at that station during the winter months. The light here is in operation, but the keeper's quarters and kitchens were left incomplete and have been badly damaged by the elements. It is expected to complete this station not later than October 1, 1903.

6. Legaspi, Albay Gulf, Luzon Island.-A 50-foot wooden tower, wooden cistern, keeper's cottage, and wire fence were built at this station.

7. Escarceo Point, Mindoro Island.-A 25-foot wooden tower, wooden cistern, and keeper's cottage were built at this station.

8. Catbalogan, west coast of Samar.-A frame tower was built at this station.

PROPOSED WORK.

The proposed work for the fiscal year 1903-4 was outlined in my report to the Chief of Bureau dated May 20, 1903. It is summarized as follows:

1. New light stations proposed.-Second-order light at Maniguin Island; fourthorder light at Capitancillo Islet; third-order light at Bajo Apo Islet; third-order light

at Bagacay Point; sixth-order light at entrance to Sorsogon Bay; sixth-order light at San Fernando Point; post lantern at Iloilo River entrance; port light at Salomague; port light at Port Bolinao; port light and 3 lanterns at Romblon; 12 port lights where commerce may demand.

2. Improvement of existing light stations.-Flashing light at Siete Pecados, sixth order; automatic light at San Nicholas Banks, Manila Bay; port lights, 30 cm. diameter, at Lipata Bank and Lanis Ledge, in Cebu Harbor; port lights at San Fernando Range; port light at Sual, Lingayen Bay.

3. General repairs.-Renovation of Gigantes and Calabazas light stations and such others as may require repairs. Under this head is included the operation of the repair shop in Manila and the overhauling of the machinery and iron structural work now in the warehouse.

4. Surveys.—A survey near Point Bolinao to determine site for a first-order seacoast light. A survey at Point Luzaran to determine new site for the light station at that point; the present site is being undermined by the sea.

This office has ordered a set of surveying instruments.

The following general plan of work is proposed:

1. To send parties immediately to Gigantes Islands and Calabazas Islands to put the stations there in thorough repair.

2. To order the illuminating apparatus and structural material for the projected year's work as quickly as requisitions and specifications can be prepared.

3. To erect temporary buildings, cisterns, and the iron tower at Capitancillo Islet, and put light in operation; then to proceed with the main buildings and retaining walls.

4. To build a tower and storehouse at Point Bagacay and then to proceed with.the main keeper's dwelling. Bagacay and Capitancillo can be built simultaneously. 5. To visit Maniguin Island and Bajo Apo Islet and prepare for beginning construction by hired labor or by contract.

6. To complete the four third-order stations at which work is now in progress. 7. To establish the minor stations and make the other proposed improvements and repairs as opportunity offers.

8. The establishment of the automatic or continuous-burning light at St. Nicholas Banks in Manila Bay should receive early attention.

CHIEF BUREAU OF COAST GUARD AND TRANSPORTATION,

Manila, P. I.

DEPARTMENT OF COMMERCE AND LABOR,
COAST AND GEODETIC SURVEY,
Manila, September 2, 1903.

SIR: I have the honor to submit the following report of the progress of the work of the coast and geodetic survey in the Philippine Islands from September 10, 1902 (the date of the last report), to August 31, 1903.

FIELD WORK.

Port Galera.-A survey was made of Port Galera and Varadero Bay, the only protected anchorages on the north coast of Mindoro. The harbor was found to be larger than the old charts had indicated.

Mangarin.-A survey was made of the vicinity of Mangarin, near the south end of Mindoro. A dangerous rock in the north end of Ilin Strait, on which several vessels have struck, was located.

Danao River mouth.-A survey was made of the lower part of this river and its entrance. This forms the only protected harbor in the northern part of Negros Island.

Capiz.-A survey is now in progress of the anchorage off Capiz, and the bays to the westward along the north coast of Panay.

Iloilo.-A survey is now in progress of the eastern entrance to Iloilo, which was very incompletely shown on the old charts.

Lingayen Gulf.-The survey of this large and important body of water was completed in July. A protected anchorage previously unsurveyed was developed in the western part of the gulf, and a deeper channel than known was found, leading from the gulf into Bolinao Harbor. The islands in the western part and the banks at the entrance to the gulf were found to have been very incorrectly charted. Two chartered launches were used in this work.

Northwest coast of Luzon.-A continuous topographic survey with triangulation has been carried along the northwest coast of Luzon from San Fernando to Cape Bojeador and eastward along the north coast of Luzon, and in a few weeks it is expected that this work will be completed as far as Aparri. The topography includes the actual coast line and the towns and highways near the coast, and all prominent landmarks. The triangulation furnishes the position of a large number of marked points, serving as a framework for this survey as well as further surveys.

Manila Bay. A triangulation has been carried across Manila Bay, locating prominent points around the bay, the islands at the entrance, and hills and mountains around the bay. This triangulation may be extended to the southward the length of the Archipelago.

Lagonoy Gulf.-A general survey of this gulf, commencing at Tabaco, is now in progress.

San Pedro Bay and south coast of Samar.-Commencing at Tacloban, a general survey of San Pedro Bay was made and extended to
