In addition to walnuts as nuts, they pay handsomely as pickles. For this
purpose they must be picked green. This could be made a most profitable
side industry in connection with large groves.
One grower had an inquiry for two carloads of green
walnuts to be used
for this purpose. Large quantities are imported annually and they sell
at very high prices.
They are also used for dyeing purposes, giving a beautiful brown shade
difficult to obtain except with walnut hulls.
Oil which is often substituted for olive oil is manufactured from
walnuts, thus suggesting another commercial avenue. One hundred pounds
of walnuts produce eighteen pounds of oil.
