indicated in Table 43 ; at most of the places indicated a large number of auxiliary stations 

 were occupied to test the uniformity of magnetic distribution. The site finally selected 

 was 12 miles west of Watheroo, where the Watheroo Observatory was established and 

 put into operation with the beginning of the year 1919.

After a preliminary examination of the region near Lima, Peru, by Mr. D. M. Wise, 

 accompanied by Mr. Allen Sterling, and reported upon by Mr. Wise (see pp. 210-211), 

 Mr. J. A. Fleming, chief of the Magnetic Survey Division of the Department, went to 

 Peru early in 1917 and took personal supervision of the investigation. The regions 

 examined are indicated in Table 44, which shows principal stations occupied; extended 

 and detailed study was made of the conditions surrounding each. Views 1 and 6 of Plate 

 5 and view 5 of Plate 6 are typical of regions examined. A location was finally decided 

 upon as satisfactory in the vicinity of Huancayo, where an observatory is now being 

 constructed and will be in operation during the latter part of 1921.

1 Two or more stations were occupied at each of these placos to tost for local disturbance. 



Mr. H. F. Johnston was detached from the Carnegie party in May 1916 while at 

 Christ-church, New Zealand, and on his way to Washington made observations on 

 Tahiti and adjoining islands of the Society Islands with a view to ascertaining the desir- 

 ability of those islands as a site for an observatorj^. On arrival in California secular- 

 variation observations were made at stations near San Francisco and near San Diego.
