February 15 to April 4, which were planted in nursery
rows very soon after being made. Only 40 of these were alive in October,
the best results being obtained with San Jose on black walnut stocks.
Sixty-four walnut grafts were placed in decayed sawdust in the
greenhouse in February and March and of these 22 were alive early in May
when they were taken out.
PECANS.
The pecan grafts, set in nursery rows as soon as made, numbered 474 and
consisted of the following varieties: Mantura, Appomattox, Frotscher,
Moneymaker, Van Deman, Stuart, and Pabst. Only one of these, a Pabst on
a piece root, lived during the season.
The grafts which were placed in the greenhouse gave pretty good results
as shown by the following data given respectively under the headings
"Earth Bed" and "Decayed Sawdust."

These figures show that 61 per cent of those in the earth bed and 65 per
cent of those in the decayed sawdust, were alive when they were taken up
early in May. Some had made a growth of from two to eight inches and
were fine little trees. Most of these transplanted grafts were set in
nursery rows and nearly all succumbed to the extreme drought of the
season.
CONCLUSIONS.
The season was so extremely dry that the practice of planting root
grafts as soon as made did not prove successful. However, work done in
other years indicated that in normal seasons this may be done with
considerable success. Placing the grafts in a greenhouse either in earth
or decayed sawdust gave encouraging results, but when transplanted in
the nursery th
