homas, already cited, both Paris green and tobacco water are said 
> be ineffectual; and here, for the first time, a remedy is suggested 
liicli has pioven to be an easy and perfect method of controlling 
le ravages of this insect. “Where it will not pay,” he says, “to 
dopt this method, and the patch is badly infested, I am inclined 
> the opinion that burning will be the most effective remedy 
over the plants with straw after the worms enter the pupa state 
l the fall and burn over thoroughly. It is possible that rolling 
vice or thrice with a heavy roller may destroy most of them but 
is somewhat doubtful.” 
In the following year this method was tried at Normal, with the 
aprovement of first mowing and then burning the field soon after 
fiffit was gathered. Phis procedure was completely success- 
il. The plants were not injured, but speedily sent up new, strong 
aves, which made a dense growth by fall; and the plants the 
lloving year weie but slightly injured by the insect. A repetition 
this treatment for two more years in succession reduced the leaf¬ 
ier to complete insignificance, and it has not since appeared in 
lat region in injurious numbers. This remedy has also been else- 
bere extensively employed, and it is now the standard method of 
i j m g ^ ie l ea f _ro ^ er - Mr. H. K. Yickroy, who has burned his 
fids over five or six times, informs me that his plants have never 
;en damaged in the least by the process. He first mows the whole 
)ld over as close to the ground as he can cut with a mower, and 
aves the cut weeds and foliage to dry a few days, so that it’may 
lrn readily. He then loosens and rakes up the straw mulching 
metimes spreading it lightly over the rows, and fires the field in a 
ntle breeze. If he had no mulching on the field, he would sprinkle 
raw lightly over it. To test the endurance of the plants, he has 
led straw a foot high on the rows, and burned it without the 
ightest injury to the strawberry plant. It is possible, however that 
ther during or immediately before a very dry time, the plants 
lght be damaged by burning. In the first instance, they might 
irn too deeply; and in the second, the new leaves might be too 
iw to start. For Southern Illinois, until the life history of the 
sect in that latitude is complete, w^e can only say that the fields 
ould be mowed and burned late in June or early in July. 
If there are any instances in which this remedy is not applicable, 
where strawberries are raised upon the same ground with plants 
lich would be injured by burning, no _ method of destroying this 
st is known, unless it be by giving chickens access to the field in 
idsurumer. Of this, Mr. Gibbs, of Minnesota, says: “My only 
'Pe of saving my crop next summer is in the. services of numerous 
oods of chickens that I intend to scatter in coops set here and 
ere about the fields; and I indulge in this hope confidently, for 
e leason that a neighbor of mine across the road from my place 
d quite a large patch entirely free from the insects last summer, 
'-hough his vines were grown from plants taken the previous year 
im my infested field. The only difference between his patch and 
Y field was that he had a hundred or so of young chickens among 
? vines all the spring, while I had no feathered protection except 
»m a few bircis that had escaped ‘the slings and arrows of out- 
?eous fortune' at the hands of our village boys.”
