Apia, Upolu Island, 1905, 1906, 1907.— The observations 

 made by G. Heimbrod in 1906 were at the first 

 absolute house, on the spit of land called Mulinum, 

 of the Samoa Observatory of the Imperial Academy of 

 Sciences of Gottingen. The observations of 1906 

 by the officers of the Galilee were made at three points. 

 One of these was the first absolute house of the Samoa 

 Observatory. The second station, designated NoTth 

 Pier, was in the observatory grounds about 50 feet 

 (15 meters) north of the absolute house. The third 

 station, designated as East Pier, was in the observa- 

 tory grounds about 50 feet (15 meters) east of the 

 absolute house. The observations in 1907 were made 

 at two stations. The first, designated Stump, was 

 near the north pier station of 1906, being about 

 10 feet (3 meters) northwest of the north pier. The 

 second, designated as West Pier, was in the obser- 

 vatory grounds about 41 feet (12.5 meters) west from 

 west wall of new absolute house. The first absolute 

 house of the observatory was being rebuilt at the 

 time of the 1907 work and it was not possible to 

 observe in it.
