introduction 
The winter of 1934-35 was warmer than normal in nearly all sections 
of the country , though a narror belt along the Atlantic const averaged 
about normal and a limited area in the Northeast Fas colder than normal. 
In general, t>recioitation for the winter "as belo~ norrral. A north-south 
belt extending froir North Dakota and eastern Montana, to the rUo Grande 
Valley '"as dry, sorre -oortions having less than half the norrral rainfall. 
Tlie region extending frorr the far Southwest to the Pacific coast, as rell 
as the "est gulf area., the Northeast, and -oortions of the Mississippi Val- 
ley, received rrore than the norrral amount of rainfall. 
Aoril i-as cooler than normal in the far Northwest and through the 
central valleys into the Middle Atlantic States. Tlie Northeastern, .South- 
ern, and Southwestern States ^ere slightly warmer than norrral. May ras 
characterized by subnormal temperatures and excessive rainfall. This condi- 
tion persisted into June over much of the country. June ^as abnorrrally dry 
in the Southeast and in most sections T_ est of the Great Plains. July had 
extrerrely high temperatures, and rainfall ras from ample to heavy in most 
sections east of the Mississippi River, but scanty and markedly deficient 
in many areas to the ^est. August r as ^arm and rather dry. 
Although temoeratures for the fall season averaged remarkably near 
normal over practically the entire country, there rere some unusual occur- 
rences. About the middle of September frost was reported in the Northeast 
and in the Lake States region. During the first reek in October freezing 
reather and killing frosts extended considerably farther south than usual 
by this date, and. in some districts in the Southeast the temoeratures r ere 
the lowest ever recorded for this time of jear. In southeastern Iowa the 
most severe freeze for the date in 65 years occurred. The outstanding con- 
dition that affected insect abundance ~as the persistent cool, wet weather 
in the spring, ^hiclx provided ideal conditions for the activity of such in- 
sects as cutworms and seed corn maggots, and, more important still, prevent- 
ed one of the worst chinch bw outbreaks in 50 vears.
