Mr. Samuel Bartley, of Eclgewoocl, says: “I think your suspi- 
on as to the third brood of the Hessian fly is well founded —I 
link there is no doubt of it. I have several times plowed my 
heat stubble as soon as the wheat was cut — not waiting to take 
locks off the ground— and the volunteer wheat was nearly de¬ 
layed by the fly; and if I neglected to plow the ground the 
icoud time, before sowing, I would be nearly sure to fail in 
tising a crop on account of the fly.” 
From Mr. John Marten, of Albion, I had the following reply: 
For three seasons past I have found the larvae in considerable 
umbers on the volunteer wheat after 'plotting the stubble under. 
his was most extensively noticed last August, when I found an 
lundance of larvae on volunteer wheat where plowing had been 
one. They were most abundant during the last few days of 
ugust and the first two weeks of (September, after which I was 
et able to visit the field for some time/' 
Hon. David Gore writes from Carlinville: “I have observed the 
y in volunteer wheat after the stubble had been plowed, but do 
it remember seeing it so far advanced as the flaxseed form.” 
Mr. F. Helms, of Heinriclitown, a farmer well acquainted with 
le fly in all its stages, sent me, in reply, the following interest- 
ig and important information: 
“I have found the Hessian fly (flaxseed stage) in volunteer 
heat every year for more than twenty years, some years in 
istly greater numbers than others. The date of the formation 
: the flaxseeds seemed to depend on the time the wheat came 
o. I have seen them in the early part of September. In 1879 
sowed, for experiment, some ten acres of wheat about the 20th 
: August on strong land. The wheat made a quick start, and 
•oked fine and well when about three or four inches high. The 
ies then deposited their eggs in great numbers, so that it was 
most impossible to find a blade free from them. Dry warm 
eather followed, and the wheat was nearly killed by the fly (now 
l the flaxseed). The warm weather continuing long enough to 
low the fly to hatch, the wheat then took a new start and made 
fine pasture for sheep during the winter and early spring, and 
atured a good crop of heavy wheat.” 
Mr. W. H. Cotter, of Edwardsville, says that he has seen the 
y in volunteer wheat in great abundance, — “particularly between 
Le middle and the latter part of September;” and Mr. Jas. R. 
filler writes from Caseyville substantially to the same effect. 
Mr. F. C. Krinard, of Bunker Hill, Macoupin county, observed 
ie volunteer wheat to contain the Hessian fly in as great num- 
3rs as wdieat sown at any time during the season, if examined 
>ur or five weeks after its coming up.
