ACKNOWLEDGMENTS. 
The planning of the observations, their character, and 
all questions of the forms of instruments, methods of obser- 
vation and of reduction, corrections, etc., the head of the 
section is responsible for. The observations themselves in 
1897 have largely been taken by Mr. Trimble and their 
reduction has been made or verified by him. During June, 
July and August, during the absence of Mr. Trimble assist- 
ing in other investigations, the observations were made 
principally by Mr. 11 . b. Alps, now connected with the U. S. 
Weather Bureau, but the reductions have been made or 
verified by Mr. Trimble. In September most of the obser- 
vations were made by Mr. J. D. Stannard. d'he sunshine 
records were measured and the monthly sums found by 
Mr. W. R. Headden, now of the senior class in the Agricul- 
tural College. 1 he diagrams representing thevarious 
observations, in figures 12 to 19 have been made by Mr. j.
