At the late Nurserymen's Convention, at Rochester, belts for placing around apple trees were exhibited with cotton fastenings on the interior surface, soaked in some poison, probably Quassia, by which the eggs are destroyed in the cotton without the necessity of taking oft' the bands and destroying the eggs. We have since received the following from a New York correspondent. " Are you favorable towards the party who claims a patent right on the mode of taking the apple worm, such as shown at the late Convention. I think, myself, if he has procurred a patent it is simply an outrage".

We are not quite sure we take in our correspondent's meaning. We have a great admiration for the man who, when he discovers a valuable fact in horticulture, gives it freely to all for the public benefit. But if one chooses to make a profit for himself by the exclusive use of his discovery, it seems a very natural thing as the world goes. It seems that the saving of the labor and trouble of changing the bands is a novel and valuable discovery. It is certainly new to us.
