of the climate conditions of eastern Kansas, it is safe to infer that the same 

 changes are talking place over the entire region of which it forms a part. The 

 rainfall and atmospheric humidity have increased and the wind velocity has 

 decreased. The change in the rainfall and wind velocity has heen in each case 

 more than 10 per cent, while the increase in the atmospheric humidity has 

 been more than 6 per cent."

Influence of spring precipitation on the yield of oats and potatoes and on 

 the starch content of i)otatoes, A. Alexandrov {Zeml. Ghaz., 1905, No. 41, pp. 

 579-581; abs. in ZJiiir. Opuitn. Agron. (Riiss. Jour. Expt. Landic), 7 {1906), No, 

 Jf, p. 515). — On the basis of experiments at the Yiatka Experiment Station the 

 author concludes that for oats INIay rains are more important than June rains, 

 the optimum precipitation during the vegetation period being about G8 mm. ; 

 for potatoes, the greater the precipitation in May and June the less the yield 

 and the starch content, and conversel,y. — p. fireman.
