Al'ocord of soil temperatures has al::;o been commenced duringthe year and will yield information as to diurnal andseasonal variations of temperature. Self-recording hygrometerand uarollletel' will also be Bet up. Most of tho informatiunpl'ovided by these records will become imllludlatelyu::;eful in connection wIth one or other investigatiun::;a,t the Institute.lJ1'a-inaye Data.-These aro Geing continued, and thetin;t several years' records togctl18r with those of the CawIlporegauges llave beon written up for publwation. Amongthe deductions which have been possible are the following:-(a) The alllount of water draining away annuallyvaries with tbe rainfall, it being large in wet years; but theamount which evaporates from bare fallow soil is almostUOllstanL for any OIle pla,ce. At CawIlporc about l81! ofwa,ter thus evaporates pel' annum, at Pu:::;a about 28/1; theL:orrespollding ligurc at Hothamsted is about 15/1. The expbllu,tiol1for the larger ~WIOllllt eva,porating at Pusa thantLt UtLwnporc prolJLLbly lies chiefly in the nature of the soil)but tili::; is a matter which remains to be demonstrated.(b) lJrailltLge from cropped land is nH,turally affectod by theextra, factor-the crop-and the drainage data have yielded::lome very intol'osting information in regard to it.
