tirred and to increase the area of cultivation as the rootspread
increases.

5. Rootstocks. For the present the plants chosen for stocks have come
from nigra, the only one that has proved itself in the matter of "take".
It does well in moist soils.

Mr. Treyves has personally tried to graft Mayette and Franquette on
_Torreyi_. He has found the "take" and the union perfect. But even
though vegetation is promising we must wait 22 years for a full test.

He proposes to lest all the "rootstocks placed at his disposal in order
to acclimatize the good French varieties to all the soils which suit
these stocks. Grafting on _J. Torreyi_ will be useful to a [_sera utile
a un_] stock that grows in dry soil, like _nigra_.

"But that is a matter we shall have to examine again in ten years, first
as regards vegetation and then in 20 years as concerns fruit
production."

Since these experiments date from '36 at the time of the Grenoble
Congress we have only 13 years to wait to learn what sort of fruit these
trees will bear and only 5 to see how they behave vegetatively.

It remains, then, only to wish "good luck" to our kind and devoted
correspondent and to thank him for his valuable documentation.

Pictorial Record of Grafting at Climax, Michigan

W. M. BECKERT, _Jackson, Mich._

Top-working black walnuts to Persian Walnuts has long been practiced by
various members of this organization. It is hoped by this series of
Kodachrome slides that a record of such top-working by one of our
members would be of interest and also show the details of just how the
work is done under actual field conditions.

Mr. Gilbert Becker, of Climax, Michigan, has been quite successful in
top-working black walnuts. Needless to say, these pictures were taken to
show how an expert goes about grafting black walnuts. Mr. Becker was
contacted as to when he would do his grafting and he mentioned that on
May 80, 1953, he would be top-working his stock. Plans were made to be
present on that date and we were fortunate in having bright weather for
taking the pictures.

The first two slides show Mr. Becker removing the scionwood from his
storage pit, selecting the scions and preparing to go out to do the
grafting. On the way to the trees that were to be grafted, the pictures
for the next two slides were taken to show the stage of leaf development
and the length of the catkins of the Thomas Black Walnut, so members in
other sections of the country c
