A correspondent says : "Will the editor of the Gardeners' Monthly, please help a reader who somehow cannot make out what he means to say on page 20 of the January number. A cut used in Dr. Houghs' "Elements of Forestry," represented the porous part of the annual layers of oak wood, as the inner part of the layer, that is, as the first formed portion of the annual growth. I understood the editor to say, two or three months ago, that the cut was wrong in this respect, and that this porous part, consisting largely of ducts, really belongs to the outer or latest part of each layer, Now, on reading the editorial notes on page 20 of the January number, I can't make out whether the editor means to tell us that the cut was right or wrong in this particular. It must be either one way or the other, and I presume the editor is clear in his own mind about it. But either he has not expressed his mind altogether or else the writer of this inquiry must subscribe himself A Dull Reader."
