A similar set of inferences are to be drawn (although less p( 
tively) from Table X., for the Northern part of the State, wh 
the first five wheat numbers show a slight gradual increase, eit 
taken alone or combined with those for barley.

Passing, now, to the table for Southern Illinois, and omitt 
the single report of injury “none,” we notice, first, a continu 
decline in the numbers for wheat, from 3,684 acres to 1,110, ? 
a continuous increase in those for oats, from 1,468 to 3,042, wl 
grass runs irregularly upward from 2,337 acres to 5,014. Corn, 
the other hand, varies without perceptible law. The combi: 
acreage in wheat and oats falls away about twenty per cent.; 
the total cultivated area is nearly uniform. 
The meaning of these complications seems reasonably clear 
1. In a country where the chinch bug has long prevailed i 
multiplied without check, it outgrows its dependence on any 
crop, and with its vast numbers and momentum of increase is s 
to maintain' itself and even to multiply where it would other? 
suffer suppression,—a conclusion which simply fortifies that alre 
drawn from previous notes on the situation in this section. 
2. We shall see later that a part (but not all) of the wheat 
cline is due to a partial abandonment of wheat in. regions wl 
the loss had been most severe in 1886,—a diminution in 1881 
the wheat area in those regions, as compared with that for 188<
