 charge of myself during the whole year. 



Mr. H. E. Annett, Supernumerary Agricultural 

 Chemist, returned to duty at Pusa on 6th November 1911 

 from Cawnpore, where he had been acting as Principal of 

 the Agricultural College. He left Pusa again on May 9th,

 tion at the Sirseah Indigo Research Station. Babus 

 Narain Lai Tewari and Narendra Nath Mitra, M.Sc. (All.), 

 are the two new assistants, who have been appointed to fill 

 vacancies which had occurred. 



2. Meteorology — In addition to the usual meteorological 

 observations which are submitted to the Meteorological 

 Department monthly, records are maintained of {i) pressure 

 by means of a barograph, (ii) soil temperatures at depths 

 of 1 in. down to 2 ft. from the land surface by means of 

 maximum and minimum thermometers, and {Hi) evapora- 

 tion from a plain water surface. 



3. Drainage Data. — The amount of water which drains 

 annually from fallow land and from land bearing crops 

 is determined at Pusa and at Cawnpore by means of 

 gauges, descriptions of which have been published.* The 

 water is analysed regularly in regard to certain constitu- 

 ents, such as nitrogen compounds and mineral matters. 

 The records of the first few years have been published as a 

 Memoirt of this Department. The chief deductions ad- 

 missible from these records were detailed in my last annual
