REPORT OF EXECUTIVE COMMITTEE xix 



Boss, Hale, and Campbell. Grant No. 70. For invcstigathig pro- 

 posal for a southern and a solar observatory . $5,000. 



In the Year Book for 1902 a proposition for the estabhshment of 

 a distinctly solar observatory was presented by Professor S. P. 

 I,angley. In the same report (page 89) the astronomical advisers 

 called attention to the lack of observatories in the southern hemi- 

 sphere, and in an appendix (pages 99 to 104) they treated the sub- 

 ject still more fully. 



In order that the Board of Trustees might be enabled to arrive at 

 appropriate conclusions, Professor I^ewis Boss, chairman; Professor 

 George E. Hale ; and Professor W. W. Campbell were requested to 

 investigate, as a Committee, the subject more fully and to consider 

 the question of suitable sites for such observatories. 



The result of the work of this committee is submitted in the 

 Accompanying Papers of this Report, pages 1-70.

 errors should be made. Professor Porro, of Turin, undertook a part 

 of the reductions and Professor Davis the rest. Assistance from pri- 

 vate persons and from observatories have contributed to the prose-
