The important question remains to be considered ; how can we 
most successfully combat this new enemy and rescue our cabbage 
crop from the destruction which appears to be impending over ii ' 
And the thought which first occurs in connection with this inquiry is, 
that having received this evil from Europe we can from thence he 
informed of its best remedies, aware that during the centuries of 
experience they have there had with this enemy every measure for its 
destruction which promises to be of value will no doubt have been 
fully tested, and those which are most efficacious will have been con¬ 
clusively ascertained. 
And we find that about the only measure recommended by Euro¬ 
pean writers is, searching out, capturing and destroying the insect 
in all the different stages of its growth. Kollar says: “ The best way 
to destroy them is picking off and killing the caterpillars, as well as 
the pupae, the latter being found attached to adjacent trees, hedges 
and walls.” Duponchel, in his Iconograph of Caterpillars, vol. l^p. 
50, says the most efficacious measure for destroying them will be for 
the gardeners to employ their idle children in capturing for the 
slaughter all the white butterflies which are flying around their cab¬ 
bages, as these are mostly females seeking places to lay their eggs; 
and slaying one female before she begins to lay, we destroy one entire 
generation of caterpillars, composed perhaps of a hundred to a hundred 
and fifty individuals. lie also recommends searching for and destroy¬ 
ing the eggs and the pupae. 
Setting children to capturing all the butterflies that come around 
the plat of cabbages, stimulating them to increased diligence by a 
trifling reward for a certain number caught, I regard as the most effec¬ 
tual mode of keeping the crop free from this enemy. They should be 
furnished with a net, a bag made of musquito netting or some similar 
fabric, about three feet long and eighteen inches diameter, its mouth 
sewed to a hoop of stout wire with the ends securely fastened to a 
handle some four feet long. With such a net the butterflies will be 
leadily caught, as they are commonly slow in their flight. 
Many of the pupae may be entrapped by placing pieces of boards 
between the rows of cabbages, elevated two or three inches above the 
ground, to the under side of which numbers will resort to pass this 
stage of their lives. A half dozen boxes open at the bottom and top, 
used for protecting hills of cucumbers from the striped yellow beetle, 
having been left lying upon their sides three yards distant from a row 
of ruta-bagas, were found with fifteen pupae in them, showing that
