INTRODUCTION 
V 
The weather of the year as a whole did not show an extreme departure 
from normal as did 1930 and 1931. Perhaps the most notable feat-ares were 
the mild preceding winter and cold March and the dry fall in the West. 
Late winter was very mild east of the Rockies, "but somewhat below normal 
in temperature in the mountain and Pacific regions, especially in the Great 
Basin. January rainfall was normal or higher in most of the country, whereas 
February was rather deficient in precipitation. 
March was warmer than normal on the Pacific Coast, tut much colder in 
the rest :>f the country, with a long severe cold wave early in the month. 
April a-.* a hay were generally slightly above normal in temperature. Rainfall 
was variable, near normal early in the spring, and rather deficient late in 
the spring. 
The summer months were near hut somewhat abcroa ." noxma.1 in tesporature, the 
northern plains being especially warmer. Sumner rainfall was variable, near 
normal on the whole, rather below normal in July, but usually sufficient for 
crops. 
The fall mcnths 7/ere near normal in temperature, with rather warm 
weather on the Pacific Coast; there was considerable, but not extreme, cold 
weather in early winter. Precipitation during the period was generally 
plentiful east of the Mississippi "but scanty westward, with drought injury 
in the hard winter-wheat region. 
The mild winter was reflected ~^y material northward advances of many 
southern species of insects, and the practically normal year was associated 
with decided increases of many of our troublesome species.
