Millions of small land animals suffer destructionduring every hailstorm in summer, and though these hail-storms are quite local, the effect is nevertheless one thatinfluences the future generations and it may change the wholeinterrelated system of life adjustments. The wind as a factor in local and geographical distributionis evident to every observer who goes afield for the valuableinformation there afforded. Aside from carrying hordes ofinsect life adrift in the prevailing southwest winds in thistemperate latitude to new habitats, other hordes suffer destruc-tion from the fact of not falling in their descent upon the earthinto a suitable environment. The seeds of plants profit bythe strong wind currents in being distributed into new fields,but many of these fall on sterile Plant and Insect AssoriATioN of thr Meadow in September A Jii/d , Ciirdiiiix .,tcvV/f some oj ils insect vixilarx, namc/jj: a /iig, l>iimlile-l>ec, and honey bee.

I once entered an uncultivated meadow to find astrong wind blowing from the southwest, which came in almoststeady wUting blasts. It was seed distributing day par excel-lence. The air was flecked with the fluffy seeds of the fieldthistles, which were accompanied with tops of grasses. Theseseeds were flying as far as the eye could see and were being dis-tributed broadcast.
