 point of the Domain, Auckland, in vicinity of Transit 

 of Venus Pier; 98.9 feet (30.16 meters) from the pier 

 and marked by the point of an arrow cut in top of

 nated as Peg //, in the observatory grounds, 40 feet 

 (12 meters) northeast of the absolute house; the 

 observatory is in the botanical gardens. The obser-

 recreation pier; on the beach just above high water, 

 about 24 paces from edge of vegetation, between the 

 sandhills and the sea. The point was roughly 

 marked subsequently by a post 4 by 4 inches by 8 feet 

 (12 by 12 cm. by 2.4 meters). The lighthouse is in 

 true bearing 323 15'. 1.

 Observatory.

Falmouth, England, 1909. The main station. A, is on the 

 Hat forming Trcfusis Point; 14 paces from the bank 

 above the rocky beach, and 41 paces from the more 

 southerly of the football goal-posts. The following 

 true bearings were determined: center of St. Anthony's 

 lighthouse tower, 308 50'.0; main flagpole on Pen- 

 dennis Castle, 339 52'.0; church spire on hilltop, 

 43 29'. 3. A secondary station, B, was also estab- 

 lished on the line joining the principal station with 

 the center of St. Anthony's lighthouse tower produced 

 northwestwardly 21 paces to a point about 24 paces 

 from edge of hill. 



Falmouth Observatory, England, 1909. Observations were 

 made at the Falmouth Observatory on a brick pier 

 in the hut used for absolute observations. A stone

EUROPE. 

 Great Britain concluded. 



Kew Observatory, England, 1908, 1910. Observations were 

 made on middle pier of new absolute house south of 

 main building. The azimuth mark used was the 

 monument north of observatory. Simultaneous 

 observations for intensity, declination, and dip were

European Russia. 



Alexandropol, Erivan, 1908. The point occupied by Assa- 

 frey in 1887 was recovered, but was not immediately 

 available, owing to the proximity of some building 

 stones and telegraph wires. Observations were made 

 at a point (not far from the 1887 station) 170 feet 

 (51.8 meters) from the bridge Mkchiants and about 

 100 feet (30 meters) from the gulch, on ground re- 

 served for military operations. The line of building 

 stones is distant east 18 paces, south 10 paces, west 

 32 paces. The following true bearings were deter- 

 mined: spire of church at Fort, 112 08'.8; spire of 

 Armenian church "Surp Nishan," 256 47'. 5; spire of 

 Armenian church "Surp Pirkich," 306 32'.3; spire 

 of old cemetery church, 356 47'. 8. A secondary 

 station was established between the main station and

 in line with main station and spire of Surp Pirkich. 



Baku, Baku, 1909. Stations located in southwest corner 

 of navy yard on south side of harbor, very near site

 50'.7; belfry spire on Harbor Church, 342 03'.6; 

 fire tower in the city about two miles (3.2 kilometers)

 were made at a point 92 feet (28 meters) 06'. 2 east 

 of north of main station. 



Baium, Kulais, 1908, 1909. The stations of 1908 and 1909 

 are practically identical, being on the beach beyond 

 the Boulevard Garden and ver>' nearly at spot
