This treatment ease, for it is local in its destruction but other attacks may occur. Gr- ease is not serious if it is carefully this way, but in occasional years prevalent as to overcome all obsta- large blocks in the orchard, insects are troublesome to quince growers in western New York, the borer, codlin moth, and quince curculio. These are well known invaders and it is not necessary to make any lengthy account of them here. The borer,—-which is particularly partial to the quince—should be dug out. If the trunks and crowns are examined in May or June and again in September or October of each year, all serious trouble may be averted. It is doubtful if the many strong smelling and caustic washes which are recommended are really efficient. Some growers recommend tarred paper tied tightly about the crowns of the trees for the purpose of keeping away the borers*. The following experience * Serious results often follow the use of tarred paper tied about trees, for the bark is likely to die underneath the paper. This is especially true if the paper is left on during the growing season, and the trouble seems to be. 12.—Quince knot caused by the rust fungus. An infrequent in- jury of quince s/iools, in app
