ven root, and then digs up and destroys those first set. His new 
Id is then stocked with fresh plants, which have never been in 
i! ltac ^ with seriously infested crowns. Too much care can not be 
cen to free the plants from dirt, in which the beetle might pos- 
>ly he hibernating, and to shake and search them for specimens 
ling in the foliage and the rubbish about the crowns. It is a 
T unusual thing to find a borer in any of these plants during 
i first or second year; not one in fifty thousand plants, accord- 
to Mr. Endicott’s estimate. 
_t is a general practice throughout the strawberry region to plow 
a field after two crops have been taken from it, planting the 
)und for a season to some other crop, usually to corn. These 
? methods will probably serve to keep the crown-borer well in 
nd. I do not think the process of ridging or hilling up the plants 
s been tried in Southern Illinois, although I have been told that 
is a favorite practice east. There, however, the crown-borer is 
t yet known to occur. 
itn short, unless experiments should prove the worth of poisons, 
plied in fall or early spring, the main reliance must be placed 
on occasional rotation, and the planting of new fields at a little 
tance from the old, under conditions to make the transfer of the 
>t impossible. 
perhaps the plan of ridging or hilling up the plants will be found 
iful in some instances. 
n conclusion, I will only add that we should bear in mind the 
t that the injuries done by the crown-borer are really much less 
ious than has been generally supposed, for the reason that it 
3 been confounded by horticulturists with other equally destruc- 
S e but very different insects, the strawberry root-worms. 
?rom these, however, it may be easily distinguished, notwith- 
nding its close superficial resemblance, by the fact that it is 
together footless, while the root-worms all have three pairs of 
tinct jointed legs on the segments next following the head.
