Yours very truly, JAMES C. JACKSON. Mr. Isaac B. Rumford, and son, hard-working farmers, of Bakersfield, Cal., have lived strictly on the “natural diet” for upwards of two years. Mr. Rumford has been a chronically-diseased man for many years; now, however, he is so far improved as to be able to do, as he says, “a good day’s work.” “It is doing for me,” he writes, “what I have been seeking and sorrowing after, vainly until now, for twenty years——giving me health. My son also finds it a perfect diet, and would not readily exchange it for any other; indeed, we both enjoy our food more than formerly on the old system. By another year,” he adds, “I shall be able to give you still more information on this subject, as others are beginning to be impressed with the advantages of this regimen.” (See Appendix.) A. R. B., of New York city, has lived chiefly on uncooked grain and fruit for upwards of a year; and his young wife, also, has tried it to a considerable extent. Two years ago Mrs. B. was threatened with consumption, and was told by her physician that unless she changed her diet (she was then beginning the vegetarian regimen) she would certainly not live a year. She “needed meat and milk in abundance,” he said. But she only lived the more abstemiously, and on coarse bread, with fruit, chiefly, and, during the past year, has eaten considerable uncooked “bread,” and all symptoms of her disease have disappeared. Mr. B. had nasal catarrh; but this has disappeared, and he now finds himself thoroughly nourished and better able than ever before to perform his duties. His diet consists of two meals,——7 A.M. and 6 P.M.,——and with but little variation, the two combined make about a half cupful each, wheat and oat groats, with five or six nice apples. His appetite has become sufficiently normal to enable him to enjoy this diet fully. This is in winter. In summer less grain and more fruit.
