After the walnuts are gathered, washed, dried and stored for a week or
so to test the correctness of their drying, they are ready to be graded
by passing over a sized screen. The choicest ones will sell at top
market prices, and the culls a little under. The Prince grove harvest is
never graded, as he finds ready sale at highest prices for the entire
output just as it runs after sorting out the few imperfect nuts.
