A California correspondent writes : "Although a stranger to you, I take the liberty to ask your assistance to determine the disease or malady affecting the peach roots, samples of which I send you. The nursery has been affected in a like manner for several years past; but the climax appears to have been reached with all the peach stocks grown last season, for now over one-half are either dead or dying. In many instances the bud refuses to start when the top is removed in the spring, but the tree soon dies instead. I have made only one or two observations in regard to it, and that is, that only peach roots are attacked by it, and that moisture of soil appears to be favorable to it. The smaller sample sent you has already been killed by it; the other sample, together with a section of the top, were taken from a tree in a fair way to die soon. I notice in the Gardeners' Monthly, which I take, there is a considerable discussion about the 'yellows.' Has this any connection with the ' yellows '? Can you suggest any remedy for this disease? If so, please inform us."

[This disease is produced by one of the small fungi, known as carbon molds; and is so very small that even good microscopists have failed to make out its exact character.

The disease known as the " yellows " is different from this; though that also is brought about by a parasitic root fungus. There is no cure for " yellows," because it has done its work before the grower is conscious of it. The rule is, to get rid of the trees, and plant others. - Ed. G. M.]
