In comparing walnut culture with fruit, one must take into consideration the fact that distance from transportation facilities is not a detriment; that there is very little expense in putting out or maintaining a walnut grove; that insects, blight and disease are unknown to walnut groves of Oregon, thus obviating the cost of spraying; that the expense of harvesting is exceedingly light; that no nut-fruit perishes—that it does not need to be sold at once, but will keep indefinitely, making a lost crop practically impossible.

It is estimated by experienced walnut growers that the annual cost of cultivation and pruning should not exceed $10 an acre, while harvesting should not exceed 20 cents per hundred pounds. It is a simple matter to figure the profits.

The original investment in a walnut grove may be made a comparatively small amount; thus it appeals particularly to those of limited means.
