Useful as a rule, but some- 
times doing harm are : Moles, 
thrushes, blackbirds, starlings, 
chaffinches. 
We extract a few notes 
on cuckoos, wireworms, and 
eelworms as examples of the 
class of instruction the work 
affords. 
The Cuckoo. — This, one 
of the most familiar of our 
summer visitors, is particularly 
useful in devouring hairy 
caterpillars, such as those of 
the bufftip moth, which feed 
on the leaves of lime, oak, 
elm, and other trees. Looper 
caterpillars, as well as the 
full-legged larvsc of other 
moths, are equally consumed 
by the cuckoo. As the summer 
advances this bird destroys 
immense quantities of the 
grubs which prey upon the 
leaves of cruciferous crops, 
notably the larvse of the 
turnip sawfly. 
The Wireworm. — Pota- 
toes may be successfully em- 
ployed as baits or traps to free 
land from wireworms. On 
some of the famous flower 
farms of Holland it pays to 
resort to this method of keep- 
ing in check the destructive 
larvjfi of the click-beetle. 
Ilerr Jongkindt Corinck, of 
Dedemsvaart, Overyssel, has 
the potatoes cut into two, or, 
if the tubers are very large, 
into four pieces, and strewn 
upon the infested garden 
ground. On the following 
morning they are collected,
