Observers' Field Reports 99 



sailboat, 100 by rail, 30 by carriage, and 109 on foot. Not counting the return ocean 

 voyage from Shanghai to Canton, the average travel per station was 134 miles. The total 

 cost of the field work of this expedition, including the comparisons made at the beginning 

 and end, was, exclusive of observer's salary, $341 , or an average of $14 per station. This low 

 figure is largely due to facilities provided by the Chinese Customs Service, as noted above. 



Previous observations for dip had been made at Swatow and Amoy by Dr. Doberck in 

 1883,^ using the instruments which I had employed in Expedition I. His results may, 

 therefore, be directly compared with mine by means of the comparison of the Chasselon and 

 Elliott instruments made at Hongkong in May, as already referred to. At Chinkiang 

 observations had previously been made bj' the Reverend Chevalier, and I reoccupied his 

 station as closely as possible. It would appear, however, to be locally disturbed, as the dip 

 at Station A, while agreeing with the values obtained by him, is not in accord with those 

 observed at Soochow to the south and Yangchow to the north, but on occupying Station B, 

 about a mile and a half to the south of Chevalier's station, I obtained values of the dip 

 concordant with those at Yangchow and Soochow. With this exception, I believe that the 

 results secured along the coast and in the Yangtse Delta will show an unaccidented field. 



Besides the very valuable assistance rendered by the Customs Service, as already 

 referred to, and the most effective aid received from the Reverend de Moidrey, my expedi- 

 tion was facilitated throughout by the foreign missionaries met with, and in particular by 

 the Honorable E. Carleton Baker, then vice-consul and acting-consul at Foochow, and bj' 

 Mr. J. F. Newman, then the agent of the Standard Oil Company at Chinkiang. 



expedition III. southwestern KWANGTUNG, JANUARY AND FEBRUARY 1907. 



This brief expedition along the southern coast of Kwangtung was undertaken in accord- 

 ance with instructions dated June 4 and December 3, 1906. The instrumental equipment 

 and field outfit were the same as in Expedition II. In January, 6 days were devoted to 

 observations at Honglok, comparisons at the Hongkong Observatory, and to the making 

 of the necessary arrangements for the proposed expedition. This work involved a round 

 trip between Canton and Hongkong. 



After further preliminary observations at Honglok on February 1, I left Canton on the 

 7th for the south coast. I was accompanied throughout by the Reverend Charles E. Patton, 

 of the American Presbyterian Mission of Yang Kiang, who courteous^ afforded me the 

 privilege of joining hun on one of his missionary journeys. In view of the facilities thus 

 put at my disposal, it was not necessary for me to employ an interpreter or recorder or to 

 provide my own cook; I had merely to share in the expenses of Mr. Patton's expedition in 

 proportion to the coolies and boats required for the extra duty my expedition involved. 

 The trip from Canton to Yang Kiang was made in a native junk towed by a steam launch 

 and occupied the best part of 3 days. From Yang Kiang we went overland on foot almost 

 due west to Kochow and thence by native houseboat to Fachow, and thence southeasterly 

 on foot to Shuitung, where a small steamer was taken which carried us back to Canton 

 on March 3. 



Observations that would have been made at Muiluk and Shuitung were prevented by 

 rain and the fact that no other steamer would be available within a reasonable tune for return 

 to Canton. Further observations after return to Canton were also rendered impossible 

 by continual rain during March and April, but some 3 days were spent in a reduction of the 

 observations secured at the following stations occupied in the course of the expedition : 



1. Canton (Honglok) Kwangtung (reoccupied between 2 and 3). 



2. Hongkong. 



3. Yang Kiang, Kwangtung. 



4. Kochow, Kwangtung. 



5. Hua (Fachow), Kwangtung. 



The total time devoted to the work of this expedition was 33 days. Observations were 

 made on 10 days and were prevented on 3 days while in the field by bad weather. The
