REMEDIES AGAINST THE HESSIAN FLY. 585 
volume of “ The Cultivator,” published in Albany in Au¬ 
gust, 1841. 
The best modes of preventing the ravages of the Hes¬ 
sian fly are thus stated by Mr. Herrick.* “ The stouter 
varieties of wheat ought always to be chosen, and the land 
should be kept in good condition. If fall wheat is sown 
late, some of the eggs will be avoided, but the risk of 
winter-killing the plants will be incurred. If cattle are 
permitted to graze the wheat-fields during the fall, they 
will devour many of the eggs. A large number of the 
pupae may be destroyed by burning the wheat-stubble im¬ 
mediately after harvest, and then ploughing and harrow¬ 
ing the land. This method will undoubtedly do much 
good. As the Hessian fly also lays its eggs, to some ex¬ 
tent, on rye and barley, these crops should be treated in 
a similar manner.” On mature reflection, I am confident 
that burning the stubble, as originally recommended by 
Mr. Havens, and advised by Mr. Herrick, is the very best 
method of getting rid of the Hessian fly. It is true that, 
by so doing, many of the numerous parasites of the insect 
will also be destroyed. But this need not give us any 
concern ; for if we can succeed in putting a stop to the 
ravages of the Hessian fly, by these or any other means, 
we shall not have occasion to mourn the loss of the para¬ 
sites. It is found that luxuriant crops more often escape 
injury than those that are thin and light. Steeping the 
grain and rolling it in plaster or lime tend to promote a 
I'apid and vigorous growth, and will therefore proA^e bene¬ 
ficial. SoAving the fields Avith wood ashes, in the propor¬ 
tion of tAvo bushels to an acre, in the autumn, and again 
in the first and last weeks in April, and as late in the 
month of jMay as -the sower can pass over the Avheat AAuth- 
out injury to it, has been found useful.j FaA'orable re¬ 
ports have been made upon the practice of alloAving sheep
