Table 2 shows the distribution of these stars in spectral type. The 

 representation of the distribution of the stars in general is good, 

 especially when it is considered that there are comparatively few stars 

 of the B class as faint as 8.0 magnitude and that the stars of the G 

 and K classes are scattered more uniformly over the sky than those of 

 the A class. 



Dr. Wilson, who has been engaged on this work, has started a card 

 catalogue of the stars selected, upon which observed positions and 

 other data concerning the stars will be entered. 



SEARCH FOR OBSERVING STATION. 



The climatic conditions at Albany are unfavorable for any program 

 of observations requiring continuity of effort over the entire year, 

 as the winters are apt to be very cloudy, and clear days are accompanied 

 by severe temperature. 



As already reported, a thorough examination of weather conditions 

 indicated that good seeing might be expected in the South Atlantic 

 States and in the Southwestern States. 



The Director, accompanied by Dr. Albrecht, spent the better part 

 of 3 months in the fall examining the plateau in the South Atlantic 

 States extending from the Coastal Plain on the east to the mountains 

 on the west. The elevation in general varied from 500 to 800 feet. 

 The ground is somewhat rolling and is largely under cultivation. 

 The first part of the expedition was confined to a region lying from 

 75 to 100 miles east of the mountains, and extending from Greensboro, 

 North Caiolina, to Atlanta, Georgia, while the second part dealt with 

 that part of the plateau lying close to the Coastal Plain. As a result 

 of the tests carried on at 10 stations, it appears that the best condi- 

 tions are obtainable in the region lying 75 to 100 miles east of the 

 mountains. 



A test of observing conditions in the Southwestern States is under 

 way, and a fuller report will be made upon its completion.
