planted deep enough to bring the point of union two or three inches 

 below the surface. Tliis is desirable for several reasons, but especially 

 that in case the plant is killed back by Tinusually severe frosts quite to 

 the ground the tree might not be wholly lost, wJiich would be the case 

 if the point of union with the stock be above the ground; for though 

 sprouts miglit come up from the stock, the roses that would appear 

 would not be the roses desired; whereas, if the union be a few inches 

 below the surface, tliere is a possibility that a sprout may be thrown up 

 from the part above the union, and thus the desired variety preserved. 



In pruning roses, attention must be given to the habit of the variety. 

 Those of a very vigorous hal>it should be moderately pruned, for if they 

 are severely cut back they will make a large growth of wood, and give 

 but little bloom. But those which naturally grow feebly should be 

 cut back more severely, so tliat the supply of sap may be sufficient to 

 make the flower-buds that are left grow vigorously, and the roses to 

 be fully developed. The form best suited to our climate is that of a low 

 bush, for the cold of our winters and the heat of our summers bear very 

 injuriously upon tall standards or tree roses. For this reason it is a 

 waste of money to buy these tree roses and weeping roses which are 

 sold through the country at from three to five dollars each. They are 

 produced liy grafting upon tall stems of the Dog-rose, but in two or 

 three years, at best, they succumb to the peculiar extremes of our 

 climate. The so-called Weeping roses, are made by grafting some 

 slender growing variety, sometimes two or three sorts of different 

 .colors, upon tall Dog-roses, and frequently the sorts that are grafted 

 upon them are tender varieties, wholly unable to endure our winters; 

 and if they live through the first summer are sure to perish during the 

 first winter, unless carefully housed on the approach of winter. 



The rose has also some insect enemies that will require to be 

 watched and treated according to their works. One of the most 

 annoying and injurious is the Rose-slug. It is a small light-green 

 shiny creature that eats the soft green portions of the leaves, so that 

 they have almost the appearance of having been skeletonized, making 

 the rose-bush look brown and very unsightly. The Slug usually 

 makes it appearance as the roses are beginning to bloom, preying first 

 upon the more concealed leaves near the ground, and ascending as its 

 food is exhausted to the higher branches; and as the number is usually 

 very great, in a short time the leaves are all destroyetl The writer
