 tendency to mildew, and this may be avoided by giv-

 to insure free circulation of air, and watering early 

 that the foliage may dry before the chill of night. 

 The remedy is flowers of sulphur dusted over the

Rose-slugs are small green worms that feed on the 

 foliage, lying on the under side of the leaves, which 

 they roll around them or draw together with a slight 

 web. The remedy is to spray the under side of the 

 foliage with kerosene emulsion, or with hot water 

 heated to 140, being careful to reach every part, or 

 to go over the plant leaf by leaf, pinching the leaves 

 between the fingers and crushing them. The rose 

 hopper, or thrip, is a small, yellowish-white insect 

 feeding on the under side of the leaves, sucking their 

 juice and causing them to turn yellow. The best 

 remedy is the whale-oil solution sprayed on the under 

 side. For rose bugs, or beetles, spraying with Paris 

 green is quite effective, but it must be used promptly, 

 as the amount of injury they can do in a short time 

 is remarkable. After using an insecticide, the plants 

 should be thoroughly sprayed with clear water, and 

 if treated with Paris green label them, that no one 

 may be poisoned by eating the rose-leaves. Roses for 

 pillows should not be gathered from plants that have 

 had any kind of poison used on them. 



Roses kept in the house during winter are some-
