964 EXPERIMENT STATION RECORD. 



than that of the humid States of the East, the sensible temperature, the 

 temi)erature actually felt by the human body, is so much lower iu the 

 arid region that it may be positively pleasant in the mountain valleys 

 and at the same time decidedly oppressive, often fatally so, in the humid 



East." 



It has been claimed that the rainfall is increasing in Utah and other 

 arid States under the influence of the cultivation of the soil and the 

 growth of forests, but an examination of meteorological data bearing on 

 this ])oint reveals no ground for belief that rainfall is either increasing 

 or decreasing.

n 221). A inouthly summary of observations at the station on precipitation anil 



temperature is given. The annual precipitation was 30.27 in. ; the niaxinnini tem-

Chlorin in rain water (Agl. Students' Gaz., 1S97, Apr., p. 88). — Observations at 

 Cir(!ncester show that for the 12 months ending September 30, 1896, the rainfall was 

 26.54 in. and that this amount of rain cimtained chlorids eciual to 31.85 lbs. of salt

Investigations on the temperature relations of different kinds 

 of soil, E. WoLLNY {Forsch. Geb. agr. Fhi/.s., 19 (1896), No. 4-5, pp. 

 305-101). — This is an account of a continuation of experiments which 

 the author has been carrying on for many years. The experiments 

 here recorded related to the temperature relations of humus, clay, and 

 quartz, and were carried out iu pots in the usual manner. Notes on the 

 experiments and tabulated data for temi)erature variations of the air 

 and soil are given in detail. The experiments cover the period from
