plicate samples higher than that obtained by
operator 3 and higher than the scores of operator 2 in 9 out of 12
comparisons.

The scores of the different samples are apparently mainly determined by
the per cent recovered at first crack and the number of quarters, at
least the only cases where the scores of operator 2 exceed those of
operator 1 are where the per cent first crack and the number of quarters
are greater for operator 2. This is related to the presence of empty
nuts.

The data obtained for the variety Thomas by operator 1 and 2 show for
the most part the same relative scoring of samples from different
sources. For example with both operators the score of the samples from
the Weber orchard was lower than that from the Jones and Baum orchards
and the sample from the Jones orchard scored higher than that from the
Baum orchard. In the samples from the Worton orchard the relative scores
are reversed. The scores oL operator 3 are quite out of line. With the
variety Ten Eyck the differences between scores of samples from
different sources are not consistent. Operator 2 obtained scores that
were essentially alike for all four samples whereas the scores of
operator 1 show differences of more than 10 points. This is related to
empty nuts in the sample. With the variety Ohio there is reasonable
uniformity in the scores obtained by all operators. This was the only
variety with well filled nuts and for that reason alone the score would
be less variable.
