these trees. Do they produce regularly? Do the nuts fill well each
year? Are the trees young or old? On what kind of soil are they located?
Just what are the factors that cause them to produce such superior nuts?

In order to try to answer some of this type of questions each of the ten
trees was visited in 1947 and a careful survey of each was made. This
was done in August, at which time the crop prospects for 1947 could be
noted. Mimeographed blanks such as the following were used to record the
desired data.
