That the scab starts early is also wellknown, and fruits may be attacked before the blossom stageis past. The sprayings with Bordeaux or cupram should begin earlyand be timed as for the leaf blight above mentioned. Somevarieties are more susceptible than others, and in the settingof orchards the selection should be made with this in mind. There are several other fungous diseases, as an anthracnose{Colletotrichum sp.), but they need the same treatment as men-tioned above. The Quince.—Rust {Gynmosporangium sp.) of the quince isquite destructive in some places. It infests chiefly the stems. Fig. 284.—Two rusted young Quince fruits. The left-hand one is attacked atthe blossom end and the other at the stem end. (From Bailey.) and fruit, upon the latter producing contorted forms with anorange fringe-like coating (see Fig. 284). It is a close relativeof the apple rust, and like it has its corresponding winter formalso upon the cedar trees. Practically all that has been said re-garding the life cycle of the apple rust applies with equal force. 2 24 THE DISEASES OF FRUITS. Remedies.—It goes without further writing that the cedartrees need to be removed from quince trees that are sufferingfrom the rust. As the quince twigs may become infested andit is possible that the rust will live over winter, then it be-comes essential that the diseased stems are destroyed. Inorchards where spraying has been carried out for other dis-eases it is observed that the rust is less abundant, and it there-fore seems probable that with the Bordeaux mixture the ru
