J. K. S., Cincinnati, writes:"Among the Germans over the Rhine, as we call their location here, there is a practice of slitting up the bark of some trees that do not grow freely. They say they are hide-bound. What is the philosophy of this practice ? It seems to me very absurd. I would as soon slit up my leg to cure the rheumatism. What does the Gardener's Monthly say?"

[Say what it has always said, that experience proves it to be an excellent practice in hidebound trees. We place our advice on the broad basis of experience, and if our correspondent really wishes to test the question in the way he himself proposes, we are ready to do it. He may take his rheumatic leg and slit it down an inch deep, if he likes, from the knee joint to the heel, and we will slit our best pear tree; and after all this has been done, and we have the effects before us, then discuss the"philosophy" of the thing. Please write us word when the comparative test is to begin, so that we may make a note thereof for the benefit of our readers. Ed. G. M].
