[1] 2 trees missing.

Data on the diameters of the tree trunks and yields of nuts at the end
of the third year in the orchard are given in table 1. It should be
pointed out first that these grafted trees produced some nuts the third
growing season they were in the orchard. This is very much earlier than
seedling trees ordinarily could be expected to bear nuts. It will be
noted that trees of Number 7916 developed a somewhat smaller trunk on
the average than the other varieties did, but Number 7916 outyielded
them about two to one, both in weight and in number of nuts produced.
The tendency of Number 7916 to bear nuts earlier and on smaller trees
than other varieties may prove to be a valuable characteristic that will
justify naming and releasing this clone as a new variety. The fact that
it matures its nuts early may also make it suitable for growing in more
northerly areas than other varieties, because the length of season
required for maturing the crop presumably is shorter than for other
varieties. However, this cannot be determined without extensive tes
