important to collect the entire crop each year from a given tree, taking
pains to destroy all nuts which contain weevil larvae. These may be
selected in a general way by dumping the freshly gathered nuts into a
tub of water. Nuts containing weevil larvae will float for the most
part, and in order to make sure of the destruction of larvae in the
remaining nuts they may be placed in a closed receptacle, and carbon
bisulphide poured over them.

One of the bud worms is sometimes very destructive to individual hickory
trees which have developed colonies, the larvae destroying the axillary
buds, and burrowing into the base of the petioles of leaves.

A new enemy which I found this year for the first time is the
_Conotrachelus juglandis_. This beetle ordinarily lays its eggs in the
involucre of the butternut. With the introduction of exotic walnuts, the
beetle has changed its habits, and lays its eggs in the herbaceous
shoots of walnuts and hickories. The larvae tunnel into the center of a
shoot, and destroy it, or seriously interfere with its nutrition.

Among the enemies of the hickory we must not forget the common field
mouse, and the pine mouse, which burrow beneath the surface of the
ground, and in winter feed freely upon the bark of the roots of the
hickories. They have destroyed many thousands of young hickories of
various kinds in my nursery, and in digging up roots of old hickories
for experimental root grafting I find that mice have been living freely
for years upon the bark of some roots.

RANDOM NOTES

Aside from the facts which have been grouped together in this paper,
certain notes may be of interest, as introducing questions for
speculation.

Are we likely to find more species among the hickories than the ones
already described? If so well described a species as the H. Buckleyi has
almost escaped observation, and if H. Mexicana is confined, as it seems
to be, to a very limited area, and if most of the hickories grow in
regions where few botanists are at work, it seems to me probable that
several species remain as yet undiscovered. These are likely to be
species which lack means of defence, and which are restricted to certain
small areas. If we make a parallel with other observations of recent
discoveries, one thinks, for instance, in Ichthyology of the Marston's
trout, the Sunapee sabling, Ausable greyling, and the Kern River trout,
confined almost to a certain stream or lake, and remaining undiscovered
