bers, of whom a very satisfactory percentage responded with reports
which usually were as complete as the age of the planted trees made
possible. Our thanks are due to all who had the patience to reply to so
searching a questionnaire. Their reward, we hope, will be increased by
nuggets of information from others. The survey committee is indebted to
the officers of the Association, to Mr. Slate particularly, who took
care of the multigraphing and mailing drudgery, and to the experienced
men who lent invaluable aid in formulating and revising the exhaustive
and detailed questions.

The results are here set forth in three sections: Northern United
States, Southern United States and Canadian. It is evident that trees
which do well in the south may act very differently in the north; yet,
to a certain and very important extent, the experience of the south has
a bearing upon conditions in the north. For example, the pawpaw, though
not a nut tree, has seemed to edge itself into the affections and
interest of many nut tree men. It is in reality a tropical fruit which
has adapted itself to northern latitudes. The pecan seems to be trying
to do the same thing. Both illustrate a way of working that nature
practices more or less with all species. By cross pollination and
selection, human hands are having a part in speeding up this process of
adaptation in pecans, Persian walnuts and other tender species. In fact,
this is one of the jobs to which the Association is dedicated.

We wish here to pay tribute to the nurserymen of this Association. Most
nurserymen are intelligent and honest but sometimes they have a tough
time of it. Their worst competitor is a nurseryman who sells seedlings
for named varieties, who advertises widely and prospers upon the work of
others. When we think of the painstaking care of the honest nurseryman,
of his days of drudgery, of the thousands of failed experimental trees
and plants that he destroys, of the service he renders his fellows, we
know that we should make slow progress without his help.

The conscientious worker in the experiment stations is in the same
category. He does his best work largely for love of it.

In addition to many letters and other valuable sources of information
this survey covers reports from more than 150 planters of named
varieties of nut trees. Many are also planters of seedlings from
selected and named varieties with which they are experimenting and from
which they are maki
