Manila Observatory and the Carnegie ocean magnetic survey in 1911-1912: Fr. Jose Algue SJ and Fr. Miguel Saderra-Maso SJ

by Quirino Sugon Jr.

Below is an excerpt of a reprint [Reprinted from Ocean Magnetic Observations, 1905-1916, and Reports on Special Researches. By L. A. Bauer, with W. J. Peters, J. A. Fleming, J. P. Ault, and W. F. G. Swann. Carnegie Institution of Washington Publication 175, vol. 3 (1917). Pages 165-170]

From Batavia the Carnegie sailed on November 21, 1911, bound for Manila by a circuitous route, arranged so as to cover the eastern part of the Indian Ocean. The course followed was south-southwest in the Indian Ocean to south latitude [30.8 degrees] and east longitude [89.4 degrees]; thence it extended to [37.5 degrees] south, in east longitude [95.5 degrees]. From this point a general northeasterly course was followed into the China Sea and the North Pacific. The Carnegie reached Manila, Philippine Islands, on February 2, 1912, having been out 73[1/2] days from Batavia, and having covered a distance of 8,291 miles; the conditions for observations were good.

At the new Manila Magnetic Observatory, situated at Antipolo, intercomparisons of magnetic instruments were made with the standards of the United States Coast and Geodetic Survey and with those of the Antipolo Magnetic Observatory. These comparisons were much facilitated through the cordial cooperation of Director Algue of the Manila Observatory and his chief assistant at the Antipolo Observatory, M. Saderra Maso, and the Director of Coast Surveys at Manila, P. A. Welker, at the time. Upon the completion of the land work and of minor repairs in dry dock, the Carnegieleft Manila on March 24, 1912, pursuing a northeasterly course off the Luchu Islands, and thence practically due east to north latitude [30 degrees] and east longitude [166 degrees]. Thence the course was, in general, southward to Suva, Fiji Islands, where the vessel, after having been considerably delayed by head winds, arrived June 7, 75 days out from Manila. The total distance covered from Manila to Suva was 8,158 miles. The track of the Galilee was crossed several times, and thus valuable secular-variation data were obtained. Effective assistance was rendered the Carnegie at Suva by various officials.
