t. In a longer season, farther south, there might be
more than one, although my experience in Mississippi was that there was
only one brood.

A word regarding methods of control. You can readily see that there is
no way of getting at the beetle with insecticides after they have gotten
under the bark. Doctor Pelt mentions the value of spraying the trees in
summer to kill adults when they are feeding on the petioles and probably
the terminal buds and younger twigs. It is rather doubtful whether it
would pay to spray hickory trees at that time, although the expense of
spraying large trees is not so great as you might think. We have had
experiences here, because it fell to my lot to spray all the elm trees
on the Campus last year. I kept very careful account of this. We sprayed
between five and six hundred trees. About one hundred are scattered over
the hillsides west of the buildings, some a mile from the water supply.
We did the work for about eighty-eight cents apiece, each tree having a
thorough spray. The largest trees on each side of the street we gave two
sprayings for a little less than forty cents apiece.

The real method of getting at this hickory bark borer is for everybody
to cooperate and cut those trees out, or at least the affected parts of
the tree, before the first of May. I know of no other effective method
of getting them. Cut them out and burn them. Some say, peel off the bark
and destroy that; but if you do that, you have got to cut off the
smallest branches and burn those, and I am afraid you would not get all
of the grubs. But it is better, if you can, to actually dispose of the
whole tree in some way.

There were three trees on the lawn infested and dying. I cut those out
in February, and that evidently stopped the ravages of the beetle. That
was carried on over the whole Campus, and it must have stopped the
injuries, because during the three or four years I was there after that,
we had no dead hickories from that cause.

That is evidently the only method of getting at them. It has been
wondered if we might not go to the Commissioner of Agriculture, and ask
him to take this matter in hand and force people to cooperate, because
it has become a rather serious problem. It is evident from a perusal of
the law that he has power to do that, and perhaps if this Nut Growers'
Association wishes to pass resolutions to bring before Commissioner
Pearson, they might induce him to take some steps to control thi
