Pre- ventive measures are decidedly the best. Dissolve one-half ounce sulphide of potassium and an ounce of shavings of pure soap in two gallons of hot water, strain and use with an auto spray. Pure soap is used because it will not hurt the foliage, and because it will discourage any acti^'ity of aphis as well as cause the sulphide of potass'um to stick better. This spray should be used about twice during the growing season; the first time after the leaves are well unfolded in the spring and the second time after the first blooming senson. It will do much to prevent mildew and aphis. After mil- dew appears there is little that can be done. The best plan is to cut off every diseased leaf and branch and burn them. Never under any circumstances allow the cuttings from a rose bush to lie on the ground—and this whether mildew is. CORNER OF ROSE SHOW, ROSE FESTIVAL PORTLAND, OREGON, imo present or not. Burn up all cuttings. The application by the use of a good powder bellows of a powder made by mixing one-third soot and two-thirds flour of sulphur to the rose bush is the best remedy after the mildew appears. But the preventive spraying with the potassium and soap solution; the pres- ence of plenty of both sunshine and air, both of which may be aided by proper pruning; the avoidance of sprinkling- roses in the evening—which, outside of mulching with reeking, fresh manure, is the most prolific cause of mildew—and the frequent and proper cultivation of the ground, so that no hard, baked crust excludes the air and sunshine from the roots, will be the best that can be done to prevent mildew. Of course, if you grow Ki
