continued daring the current year. The results may be sum- 

 marised as under : 



(1) That crops like lucerne, groundnut, &c,, grown on the 

 black soil of Surat either in beds or on ridges require irrigation 

 water equal to between 4 to 5 inches of rainfall after a month 

 or a month and a half from the time the rains stop, and that sub- 

 sequent waterings are required at intervals of 15 days equal to 2 

 to 3 inches of rainfall. But should irrigation be given only once 

 a month instead of every 15 days then an application equal to 

 3" to 4!' of rainfall should be given. As the season advances and 

 the temperature goes up a heavier application will be found 

 necessary so that in the hot weather an increase equal to 1" of 

 rainfall over the ordinary cold weather amount should be 

 given. 



In the case of drilled Deshi cotton two to three months after 

 the rains cease, when the soil has not cracked so badly as it does 

 later on in the hot season, irrigation water for the first watering 

 equals 5^ to 6^ inches of rainfall and the subsequent waterings 

 at intervals of twenty days require water equal 3 to 3| inches 



of rainfall. 







Trials with, new implements 



36. Two iron hand-gins and three iron 'mots' (buckets 

 for raising water) were tried on the Station during the year under 

 report with the following results : - 



The iron hand-gins were received from the Inspector-General 

 of Agriculture in India. They are on the principle of McCarthy 

 gins, but have no moveable knives and the roller is studded with 

 small pins. Every effort was made to get them to work, but the 

 cotton always stuck to the roller and was gradually chopped into 

 fine particles. 



Of the two iron c mots/ one was [received from Ndsik and 

 another from Belgaum. 



The first worked like the Sundhia leather c kos ' with the 

 only defect that it took a very long time to fill. This makes ifc 

 useless. The price is Us. 9. 



The second from Belgaum weighs 50 Ibs,, i.e., double the 

 weight of an ordinary * kos/ It is circular in shape and though 

 it works well if cautiously used, it has some drawbacks, viz.,
