tree will grow well; and we must have
nurserymen draw our attention to this difference, when they are sending
trees out to us for northern planting. That is a thing that may not be
determined right now, but nurserymen must be able to report upon
comparative ripening times of various kinds of pecans to be sent north.

We will have the report of the Committee on Nominations.

[The report was accepted and the nominees elected.]

President Morris: We have with us Professor Herrick, who will present
his paper on the subject of the scolytus beetle. Professor Herrick has
prepared his paper at our request since we came here.

THE SCOLYTUS BEETLE.

PROF. A. W. HERRICK, ITHACA, N. Y.

With a residence of a little over a decade in the South, I became more
or less intimately connected with a good many of the nut growers of the
section, especially the pecan growers. I found them there an intelligent
body of men.

The President has asked me to talk just a little on the hickory bark
borer. While in Mississippi, I first came into contact with the hickory
bark borer by its work on the hickories on the lawn in front of my house
and on the Campus. It began killing the trees. I had ten or a dozen
trees on the lawn that were from six to eight inches through, and they
had made a fine growth but they began suddenly to die. First, I noticed
the leaves falling in the summer time, then later in the winter the
branches began to die at the top. On investigation, I found that it was
this little hickory bark borer. We carried out, as a result of that
investigation, a few experiments, and extended them over the Campus,
following the recommendations of Doctor Hopkins of the Department of
Agriculture, Washington. The results were pretty gratifying. I was able
to save those trees on the lawn, and during three or four years
succeeding the time we got these experiments into practice, no more had
died, and they had kept on making a good growth; and I believe the
ravages of the beetle had been checked.

The little beetle belongs to a family called the _Scolytidae_--very
small beetles that burrow through the bark of trees, and between the
bark and the wood, partly in the bark and partly in the wood. These
beetles are interesting in their life history. The female bores through
the bark, and then she builds a channel partly in the wood and partly in
the bark. She goes along and digs out little niches all along, and in
each one of these, depos
