apping in the wind. If they are to be used they must be
fastened so as not to move with the wind. Mr. Bixby has an excellent
label made on an aluminum strip printing machine. It has a hole in each
end and is fastened with a heavy copper wire. He uses two of these
labels on each tree. Dr. Morris sometimes uses a heavy wire stake to
which he fastens the labels. A good method of attaching labels, and one
that does away with the risk of girdling the graft or tree, is to fasten
the label to a staple driven into the tree. The matter of labels is a
troublesome one for they will get lost no matter what you do.

Other conveniences of equipment are a small whetstone, a small hammer,
matches, and some volatile oil, like citronella, lavender, wintergreen,
or other black fly and mosquito repellant. It is almost suicidal to slap
a mosquito on the back of your neck with a keen grafting knife in your
hand. A supply of parowax and alcohol for the lantern's sake should be
remembered.

_Technique_

If the stocks are vigorous and active, and the scions full of vitality,
I doubt if the technique is of chief importance, provided it is
ordinarily good. However, a good technique will increase the percentage
of success. One should have a variety of methods at command for varying
conditions of stocks and scions.

One may come as near 100% success in grafting hickories as one is able
and willing to observe all the known factors of success. I think that we
can say now that the factors of success in hickory grafting are known.
They are a vigorous and active stock, a scion of abundant vitality,
coaptation of the freshly cut cambium layers and prevention of
desiccation.

The stock and scion have already been considered. How is coadaptation
best obtained? One of the best methods, one that can be used in all
seasons and in most conditions of stock and scion, is the side graft,
the one that Mr. Jones uses in his nursery work. That is the best
argument for this graft. It is, perhaps, the simplest, and at the same
time one of the most difficult, of all grafts. The scion is cut wedge
shaped and pushed into a slanting incision in the side of the stock. Mr.
Jones's modified cleft graft is only a side graft made in the top of the
stock after cutting it off. The difficulty lies chiefly in cutting the
scion and the incision in the stock so that the fit will be perfectly
true. This requires practice.

The bark slot graft, as Dr. Morris calls it, I have
