n cold weather. Cohesiveness of molecules of the mixture is such that
remelting in the hot sun may not destroy the effectiveness of this
protective coating in hot weather.

Since the author has depended upon this mixture he has grafted peaches,
apples, hazels and hickories successfully in midwinter as well as in
midsummer. Many other kinds of trees have been grafted successfully out
of the so-called grafting season but these four kinds which represent
two of the "easiest grafters" and two of the "hardest grafters" will
suffice for purposes of illustration.

According to old-established idea trees may be grafted successfully only
from scions that have been cut when dormant and stored in proper
receptacles. This is what we may term "mediate grafting," a considerable
length of time intervening between cutting the scions and inserting the
grafts. On the other hand what we may call "immediate grafting" is the
taking of a scion from one tree and grafting it at once in a tree that
is to receive it. Mediate or immediate grafting may both be done at
almost any time of the year, winter or summer, spring or autumn.

When preparing the scion for immediate grafting in the spring or early
summer it is best to cut off all the leaves and herbaceous growth of the
year. We then depend upon latent buds situated in the older wood of the
scion. The latter may be one year or several years of age.

In midsummer when top buds have formed we may remove only the leaves,
allowing the growth of the year to remain and to serve for grafting
material.

In experiments with the apple for example it was found that mediate
grafts inserted on July 10th in the latitude of Stamford, Conn., began
to burst their buds five or six days later. Immediate grafts inserted at
the same time began to burst their buds about fifteen days later from
buds of the year and about twenty days later from latent buds in older
scion wood.

New shoots from these mediate apple grafts continued to grow as they do
in Spring grafting. Immediate apple grafts on the other hand put out
about six leaves from each bud and then came to a state of rest with the
formation of a new top bud. After about ten days of resting these new
top buds again burst forth and grew shoots like those of the mediate
grafts.

The philosophy of these phenomena would seem to include the idea that
the mediate summer grafts had contained a full supply of pabulum stored
up in the cambium layer. The immediat
