Observers' Field Reports 157 



By October 5, Mr. Brown had completed the Manchurian work, adding 6 Fritsche 

 stations to those already reoccupied by our expeditions; he then proceeded direct to 

 Chungking in Szechwan, and started on an expedition south and west across Yunnan 

 to the Burma border. 



The details of my own expedition are as follows: Accompanied by Mr. H. J. 

 Fairburn of the English Baptist Mission at Sianfu as interpreter-companion, I left 

 Pehtaiho on July 5, 1916, after a few days' official conference with Mr. Brown, and 

 traveled by rail to Tatungfu, in Shansi, arriving there Saturday, July 8, at sunset, having 

 spent 2 days in Tientsin purchasing supplies, effecting repairs, etc. We left Tatungfu 

 at 10 a.m., July 10, with pack mules, and reached Hokow on the Yellow River at noon 

 on July 19. At Hokow there was considerable difficulty in hiring a boat owing to mar- 

 tial law prevailing along the river which is the boundary between Shensi and Shansi 

 provinces along the stretch considered. Shensi had not yet recognized the new govern- 

 ment at Peking. The boat guild also held out for a big price, which we had finally to 

 pay. We left Hokow on July 23 and arrived at Tungkwanting August 10, 1916, having 

 observed at 8 stations on this north-south stretch of the Yellow River. From 

 Tungkwanting the party came by cart and pack mules to Kingtzekwan in Honan, 

 situated on a tributary of the Han River, by which we reached Hankow September 9, 

 at midnight. 



From Tientsin to Tungkwanting my party included Mr. R. E. Baber of the Canton 

 Christian College, whose share of road expenses was covered personally. He assisted 

 heartily in the work of the expedition, and his presence added to the security of the 

 party in traversing a disturbed region. 



From Hankow I went direct to Peking by rail (September 12-13, 1916) to arrange 

 for Mr. Brown's further work. I also embraced this opportunity to report in person 

 on the work of the Department in China to His Excellency, President Li Yuan Hung, 

 and to the Honorable Chen Chin-tao, Minister of Finance, then acting also as Minister 

 of Foreign Affairs. Both expressed sincere appreciation of our work, the published 

 reports of which had already been transmitted to the Chinese Government. 



The details of arranging for Mr. Brown's further work necessitated such delay that 

 during the latter half of September I took advantage of this circumstance to enjoy a 

 needed holiday until October 1. Mr. Brown joined me at Pehtaiho on October 5, 1916. 

 Comparisons of my dip circle No. 206 with his No. 177, which had suffered a fall in Man- 

 churia in August, were made on October 5-7. Circle No. 206 was forthwith given to 

 Mr. Brown to replace No. 177. On October 21,1 left Shanghai by rail, where I arranged 

 through the courtesy of the Zikawei Observatory and Admiral Winterhalter, command- 

 ing the U. S. Fleet in Asiatic Waters, for the transmission of time signals by wireless to 

 Mr. Brown at Hankow. These were sent by the French wireless land station in direct 

 communication with the Observatory and were received at Hankow by the U. S. S. 

 Monocacy. At the end of these experiments, which were only partially successful, owing 

 to low power of the apparatus on the Monocacy, I left Shanghai October 30 by steamer 

 for Canton, arriving there November 3, 1916. Since then I have given such time to 

 the Department's affairs as the supervision of Mr. Brown's work and expedition required. 

 On April 11, 1917, I left Canton for Hongkong, and sailed for the United States April 12 

 on the Empress of Asia. 



The magnetic field in the regions covered is quite regular and of small declination 

 throughout, varying from to 5 W of N. A marked local disturbance seems to be 

 indicated by the observations on the summit and near the base of Omeishan in Szechwan, 

 but more data are needed. The local disturbance indicated by Fritsche's observations 

 in Chihli at Futuyii (8 13' W) and at Pekow (2 02' E) was not verified, the generally 

 prevailing field of about 3 W being found to obtain at these places also.
