INSTITUTE, PUSA, FOR 1916-17 23 



Government Presidency College the question of attracting 

 students to Pusa for research work. 



In April Mr. Barnes made a tour in the Punjab, visit- 

 ing Lyallpur and Lahore. At Lyallpur he settled the 

 details of the work to be done on canal seepage and at 

 Lahore attended two conferences, one on the problem of 

 canal seepage and water- logging in the Punjab and the- 

 other on the reclamation of saline barren land on the Lower 

 Bari Doab Canal. 



II. Meteorology and Drain-gauges. 



The work referred to in last year's report has been con- 

 tinued. Waters and crops from the Cawnpore drain- 

 gauges are also being analysed as usual for the United 

 Provinces Department of Agriculture. 



III. General analytical work and assistance given to 



other Sections. 



Eighty-six soils have been analysed this year from 

 different sources, 19 samples oi manure or materials pro- 

 posed as manures, 75 samples of feeding stuffs and 34 

 samples of water. Amongst the materials proposed as 

 manure were spent mohua (Bassia lati folia) flower and the 

 ash obtained by burning the waste tobacco butts from 

 tobacco factories. 



Two samples of shaftal (Tri folium reswpinatum) hay 

 which had been reported as giving rise to cases of poison- 

 ing were examined for the Imperial Economic Botanist, 

 no poisonous alkaloid or cyanogenetic glucoside could be 

 detected. 



A sample of olive fruit from a Mediterranean variety 

 grown at Taru was analysed and found to contain a high 

 content of oil. A sample of ajwan (Carum copticum) resi- 

 due, obtained in the manufacture of thymol, was analysed, 

 the results pointed to the possibility of this residue being 

 used either as a cattle food or manure. Actual trials to 

 utilize this substance are in progress.
