I have several Chinese chestnut seedlings which are making a fairly good growth and in time may become productive trees.
We have one hybrid white oak which has an edible kernel but out of about one hundred nuts you might get one wholesome one free from weevils. The tree is very old and is rapidly declining. The nut is small but the tree is quite prolific. I merely mention it to show that there are possibilities in developing the oak. I think our mutual friend, J. Russell Smith, would probably like to hear this as he advocates the use of oaks, and I agree with him that there are possibilities for human food to be used first-hand. I am all out of sympathy with second-hand food production as pork or beef or any meat products, as you know. One reason is that it is economically wrong as it takes many times more acreage to produce meat than vegetables for the same amount of food energy to be derived. My authority, the Encyclopedia Brittanica, which says it takes 64 pounds of dry fodder to produce 1 pound of dry beef, and 32 pounds of dry fodder to produce 1 pound of dry mutton, etc., etc.
There has been too much accent put on the profit to be made on nut production. No matter how much income a man may receive, if he has not learned to save out of that income he will never be better off for having received it. Now, nut trees offer a particularly practical way of saving out of income. If one has a large family to feed the saving may amount to a hundred dollars or more a year. When this fine food, contained in the kernels of nuts, is used right in your own family, and supplies the family's entire requirements of nuts, you will find that you have made very substantial savings in your family food budget.
First of all, it is different from income from the sale of nuts because when you sell nuts they must be sold in the competitive market, and usually to the wholesaler if you have a considerable amount to dispose of. Therefore you save the profit made by the wholesaler and the retailer by using your nut crop rather than selling it. This is really being thrifty. If you have a large crop of nuts you will find that you can easily increase the uses in combination with other foods so that less other food has to be purchased in order to meet the family needs. And with the higher prices of ordinary foods you can easily visualize what a tremendous saving this might be.
