know of some who have but a few plants, that destroy this insect with Persian 

 insect powder. 



Rose Bug. — Fortunately this terrible scourge does not flourish on soils of 

 a heavy nature, where roses succeed the best. The bug loves a light, warm, 

 sandy soil. The coal oil emulsion is the best remedy that we know of, with the 

 addition of carbolic acid. No insect can relish the flavor that pervades the 

 plant after a mixture containing ever so little of the acid has been applied. As 

 rain removes all traces of the insecticides, they must be applied more frequently 

 during rainy weather. 



Rose Slug. — This insert is about half an inch long; they are semi-trans- 

 parent and have a slimy appearance- They are easily destroyed with hellebore 

 powder, finely sifted coal ashes, or even road dust, if dusted over the foliage often. 



Mildew. — This fungous disease is often caused by sudden changes in the 

 temperature. It is most troublesome where the roses have not sufficient exposure 

 to the light and air. We use, with success, soot and sulphur mixed, frequently 

 dusted over the foliage from a muslin bag, until the disease disappears. 



Coal Oil Emulsion — Soft soap, one quart, add two quarts of water and 

 bring to a boil. While boiling, add gradually one pint of coal oil, stirring 

 vigorously for several minutes. To use, add fourteen parts water to one of the 

 emulsion. Mix thoroughly and apply with hand syringe or hand whisk. 



A Word for the Ever Blooming Roses. — For planting out for summer 

 bloom, we consider these roses to be indispensable. They bloom without 

 ceasing from June till frost. They can be had in so many colors and shades 

 not attainable in the hybrid perpetual class. They possess a fragrance peculiar 

 to themselves. We find them less liable to insect pests than the hybrid per- 

 petuals, and lastly, they can now be had as cheaply as ordinary bedding plants. 

 Two-year-old plants, while costing more than younger ones, are sure to grow and 

 bloom at once, and are preferred by many.

 without protection," read with protection, and the rest the same. 



Never use big rough grasses like timothy on the lawn ; stick to the fine var- 

 ieties as Kentucky blue-grass, red top, and Rhode Island bent grass. These fine 

 grasses form a large proportion of the mixed lawn grasses you buy at the seed 

 stores, and any one of them, especially the Kentucky blue or red top, used alone 

 will make a capital lawn. You may also include, or sow separately all over, a 

 little white clover ; never, though, sow either yellow or red clover on the lawn.
