disturb the root. The effect is that with the same
amount of pushing power from the root, we have a decreased area over
which that energy is spread, and it results in apparently increased
growth. I am not quite sure if we were to measure it up in a scientific
way, we would actually find it was increased growth. There are fewer
branches, but they have made greater length. In the case of grafting our
pecans, we cut off our tops, set a two-bud scion in the root, and
usually but one starts and receives all the vigor from the established
root, instead of the vigor being distributed over several buds on the
original seedling top. We have as a result of that concentration of
vitality increased growth. I think that theoretical explanation will
stand fairly well, because it seems to be directly in line with the
effect of winter pruning.

Mr. Reed: I would like to ask Professor Craig to what extent he would
select seed for nursery purposes? What influence would the characters of
the parent tree from which the seed came have on the grafted tree?

Professor Craig: I don't believe that we can expect the characters of
our stock to affect the scion to any extent. I think what the nurserymen
should have in mind and keep in mind is a good, vigorous stock, and as
many stocks as possible,--as he can get out of a pound of nuts.
Otherwise, I don't think it cuts much figure. In that connection there
is a principle which I have discovered by experience, namely, that if
you are growing stocks it is wise to get your nuts as near your own
locality as possible. My experience last year in planting five hundred
pounds of northern grown nuts in a southern locality, and five hundred
pounds of southern grown nuts in the same locality, gathered in that
locality, is that I got fifty per cent more trees from my southern grown
nuts than northern, and trees that were fully thirty per cent better.

Mr. Littlepage: Where were your northern grown nuts stratified?

Professor Craig: They were not stratified. They were planted as soon as
they were received, and they were received within two weeks from the
time they were taken from the trees.

Mr. Littlepage: I am inclined to believe that if your northern grown
nuts had been stratified in the North, and undergone the customary
freezing and thawing, then had been taken up in the spring, you wouldn't
have seen that difference.

Professor Craig: I think that point is well taken.

President Morris: There is no
