Doctoring Trees

Russian Entomologist's Novel Method of Developing Them.

A new method of feeding trees and plants without the agency of the roots has been discovered by the well known Russian entomologist, M. S. A. Mokrshezki, who has explained his discovery in a lecture before the Imperial Botanical society of St. Petersburg, says the New York Commercial Advertiser. He has invented apparatus by which he can introduce into the stems of apple and pear trees salts of iron either in the form of a solid or in solution. The effect of the chemicals is, on the one hand, completely to cure the tree of chlorose, and on the other to stimulate its growth in an important degree.

Among other extensive researches the scientist has applied his theory to 800 fruit trees growing on the southern shore of the Crimea. By introducing dry sulphate of copper into the stems he produced an unusual development of the trees, as many photographs testified. M. Mokrshezki considers that in this way the size of a fruit tree can be increased, its color improved and varied and its diseases removed.
