Dr. LeBaron, speaking in his second report of the operations of 
the Chinch-bug in 1871, remarks that the spring wheat over the 
Northwest, “was reduced to not -more than a quarter of the average 
crop.” 
The statistical reports of the Agricultural Department give the 
yield of wheat per acre for 1870, 1871 and 1872, over this region, as 
follows:

I presume *the estimates made by these two parties were based 
on statements received from individuals and then applied to the 
whole region embraced. The statistics as given show that the 
crops of these two Chinch-bug years were about up to the average; 
in fact the wheat crop in Illinois was larger in 1864 and 1871 than 
iii either the preceding or following year. 
While I think the estimates made by Drs. Shimer and LeBaron 
were entirely too large, yet I am not disposed to cast them aside 
wholly because they do not agree with the statistics of the Agricul¬ 
tural Department. They were made by men of mature judgment, 
conscientious, and of scientific attainments; made in reference to a 
matter with which they were, in part at least, personally cogni¬ 
zant. Their guesses were about as good as the guesses upon which 
. the crop estimates of the Department were made. That there is an 
error somewhere, and a very great one, is evident. I leave it with 
the reader to form his own oninion.
