9. Wheat as a decoy .—The preceding measure suggests to us 
another, which is well worthy of the attention of the agriculturist. 
The facts recorded respecting this insect, clearly show that it is the 
earliest sowed and most forward fields of grain that are most infest¬ 
ed. The fly is attracted to these fields, and finding a more luxuriant 
vegetation, and a more shady covert here than elsewhere, and meet¬ 
ing with all the accommodations which it desires, it here remains, 
even though adjoining fields separated only by an open fence, have 
come forward sufficiently to afford at least a part of the brood, quar¬ 
ters equally as comfortable. To us it appears evident, from these 
premises, that if one or two acres across the middle of a large field 
be sowed with wheat about the middle of August, all the flies in the 
vicinity will be attracted to this point, and there retained ; so that 
it will be perfectly safe to sow the remainder of the field by the 
middle of September. If the Ilessian fly is common in the neigh¬ 
borhood, the early sowed strip will be badly infested. If so, let it 
be turned under by the plow, either after two or three severe frosts 
have rendered it certain that the season for depositing the eggs is 
fully past, or early in the following spring—resowing it with win¬ 
ter wheat in the former case, or with spring wheat in the latter. 
By this procedure all the larvae will be buried and perish. Only in 
one contingency, as we can perceive, will this plan be inexpedient or 
liable to fail, namely, when the flies are present in such vast num¬ 
bers, that the decoy thus prepared is inadequate fully to accommo¬ 
date them. Upon this point, the amount of damage done at the pre¬ 
ceding harvest, will enable the cultivator to judge with a considera¬ 
ble degree of certainty. The advantages which this plan promises, 
are, that it draws all the insects of the neighborhood together, and 
destroys their entire progeny ; it enables most of the grain tp be 
sowed as early as is desirable ; and finally, there will no second or 
spring generation come forth in the field to attack any part of the 
crop. This measure therefore, should receive a fair trial from some 
intelligent wheat grower in a district suffering under this pest. 
10. Deeply covering the seed .—From the letters of a King Wil¬ 
liam County Farmer, and from the specimens furnished by him to 
Mr. Garnett, which are figured in the American Farmer, (vol. ii. p. 
174,) the following facts would seem to be conclusively established,
