REPORT OF THE IMPERIAL AGRICULTURAL 

 CHEMIST FOR THE YEARS 1907-09. 



(J. W. Leather, Ph.D., FJ.C, E.C.S., ard H. E. Annett, 



B.Sc, M.S.E.A.C.) 



1. The Imperial Agricultural Chemist held charge of 

 this section till April 14th, 1909, vvhen he proceeded on 

 leave, and Mr. H. E. Annett, B.Sc, M.S.E.A.C, Supernu- 

 merary Agricultural Chemist, was appointed to officiate for 

 him. Mr. Annett acted as Agricultural Chemist at the 

 Poona Agricultural College from August 13th to November 

 22nd, 1908. 



2. The several subjects which are under investigation 

 may be conveniently referred to as follows : — 



3. Meteorology. — The usual meteorological records are 

 kept by this section and forwarded monthly to the 

 Imperial Meteorological Department. 



4. Rainfall. — A self-registering rain gauge was fitted 

 up at Pusa and used during the monsoon of 1907 in order 

 to obtain some information regarding the rainfall per 

 unit of time. This is wanted in connection with the esti- 

 mates of the amount of rain water which runs off the land 

 during heavy rains. The instrument was one which was 

 fitted up by the Imperial Agricultural Chemist locally, and 

 yielded only approximate data, and a more exact instru- 

 ment will be necessary; but such data as wxre obtained 

 show the heaviest falls during the monsoon of 1907 to be 

 under 2" per hour. The monsoon was, however, a very 

 weak one and included only one really large fall. 



5. Evaporation. — An evaporimeter has been experi- 

 mented with in order to determine the amount of water 

 which evaporates from free surfaces of water. The results 

 so far have not been very satisfactory.
