on until March 20 when the vessel returned to Manila, leaving April 1 en route to the working grounds north of the Balintang Channel.

The season off the north coast of Luzon was closed on July 30 and the Pathfinder returned to Manila for repairs and installation of fathometer, and again sailed for the field on October 19 for work on Favorite Bank westward of the Sangboy Islands.

The Fathomer."-Having completed annual docking and repairs, this vessel left Manila on February 24 to undertake the work in the vicinity of Cap Island in the Sulu Archipelago which was carried to Pearl Bank. The work was suspended April 2 and the Fathomer proceeded to the east coast of Luzon to extend surveys along that coast northward. The success in carrying the work to completion as far north as Dingalan Bay is the second most important achievement during the period covered by this report. Closing its season October 12, the vessel returned to Manila for repairs and installation of the fathometer. En route to Manila, the tide gauges at Biri Island and Tical Island used in connection with current predictions in San Bernardino Strait were taken in, a year's tidal record having been obtained at these stations.

Completing repairs and installation of the fathometer on December 7, the vessel proceeded to the unsurveyed area 30 miles westward from the entrance to Manila Bay. This area of 784 square statute miles was covered in 7 days with 501 miles of sounding lines, the depths ranging from 60 to 1,400 fathoms. The work was done in connection with the adjustment and calibrating of the newly installed fathometer.

The Fathomer left Manila December 17 for work in Sibutu Passage, and to extend the triangulation from Tawi-Tawi Island to the islands between Sibutu Passage and Alice Channel. Field work was under way December 30.

The Marinduque."—This steamer was at Manila January 1 to April 16, 1927, for repairs at the insular repair plant, after which it proceeded to Murcielagos Bay on the north coast of Mindanao to complete the topographic and hydrographic surveys of that area. On the way, the vessel stopped at Mangarin and Iloilo for gravity observation and chart revision work. Camping parties were put out for preliminary work at Murcielagos Bay from which the vessel proceeded to Borongan and Surigao where gravity observations were also made. Work in Murcielagos Bay was completed June 2 and the Marinduque proceeded to Zamboanga.

The Marinduque continued field work on the northwest side of Tawi-Tawi Island to October 15. The work was suspended in order that the vessel could return to Manila for repairs and to install the fathometer. Although the vessel did not have sufficient number of officers to work to full capacity during the last six months, a very satisfactory work has been turned in. A complete survey of the inshore areas and channels between Cap Island and Pearl Bank was accomplished, carrying the hydrography to about the 200-fathom curve. Work along the north coast of Sanga-Sanga and Tawi-Tawi Island was then taken up and extended as far as Simalac Island, after which the vessel returned to Manila and remained at Engineer Island to the end of the year for lack of sufficient funds to make needed repairs.

The work accomplished by the field parties from January 1 to December 31, 1927, comprise the following figures:

Another important achievement during the time covered by this report is the extension of the scheme of triangulation through the Cagayan Valley by Lieut. E. B. Roberts with the aid of Filipino surveyors from the bureau of lands. work accomplished by Lieutenant Roberts extends from the north coast of Luzon to within 45 miles of Lingayen Gulf. The positions of all prominent mountain peaks of the Sierra Madre Range on the east coast of Luzon have been determined, giving sufficient points for the off-shore hydrography on the east coast.

FIELD STATION

The practice of forwarding field data to Washington for final revision and publication continued until the rapid advance of commercial development and the requirements of the Army and Navy called for immediate distribution of new charts as the surveys advanced. To meet these requirements there was established at the Manila field station September 1, 1921, a complete photolithographic printing plant. Funds for the plant were supplied by the Philippine Legislature. In addition to the primary object of printing Coast and Geodetic Survey charts at Manila for immediate use, the printing of topographle maps and much miscellaneous lithographing required by other bureaus of the insular government and the Army Engineer Department have been done.

The Coast and Geodetic Survey charts, as now compiled and published at the Manila field station, cover all parts of the Archipelago. Every port of importance has been charted and from the large stock of charts on hand navigational information is quickly supplied.

ADMINISTRATIVE DIVISION AND ACCOUNTING SECTION

The per

The duties coming under this division are exceptionally diversified. sonnel are interchangeable for almost all duties and with the exception of the accounting section functions as a single unit without sections. Upon this division devolves such duties as the keeping of accounts; collections and disbursements; correspondence and records; personnel work; custody and maintenance of the building housing the office; supervision of sales of insular publications and maps, besides performing the duties of shipping office, instrument section, property section, and purchasing agent for the survey ships.

This division has been principally engaged during the year 1927 in completing hydrographic sheets; chart compilations having been advanced to a stage where it was necessary to await the completion of field sheets or compile from unverified sheets. Considerable routine work of chart construction, receipt and registry of field sheets and descriptive reports and furnishing sheets and miscellaneous information to field parties and the general public, rounds out a busy year for this division and the accomplishments are very satisfactory.

PHOTOLITHOGRAPHIC DIVISION

The work of this division has continued to be highly satisfactory. It is believed that there are no commercial firms in the Philippine Islands doing similar work who have as highly trained men; this and the more modern equipment of its plant account for the many applictions at said office by firms and individuals for photolithographic work for the reason that the work can not be performed by private concerns.

COMPUTING DIVISION

This division has continued to function in a highly satisfactory manner. Reduction of tidal records has been kept up to date and the computation and adjustments have steadily progressed.

CHART DIVISION

In addition to the sale of charts and other publications, a great deal of nautical and other information of a technical nature are furnished the public by this division. Shipowners and masters, government engineers, and engineering companies are continuously calling on this division, through correspondence or in person, for such nautical and other information, invaluable to them, as the Coast and Geodetic Survey has procured and worked up.

GEOGRAPHICAL DIVISION

This division is in charge of the compilation of geographical data and map construction work. A new edition of the 1:100,000 scale map of the Philippine Islands was completed and ordered printed, and a new edition of the 1:200,000 maps of Negros and southern Luzon is in progress.

FINANCIAL STATEMENT

The general expenses of the bureau for this year amounted to P229,141.08P115,131.48 of which was paid by the United States Government and P114,009.60 by the government of the Philippine Islands.

The receipts for the sale of maps during the year 1927 totaled P1,566.80.
