Insects — The little dark green caterpillar that destroyed the foliage of Roses to such an 

 extent last summer, is raised from eggs laid in layers on the under side of the leaves about 

 mid-summer. I suspect the female moth or fly, like the wasp, hybernates in some hole or 

 corner in an old wall for instance, and therefore it is next to impossible to discover and 

 destroy it. 



All lovers of Roses should not forget to plead the cause of the true Aphis Vastator — the larva 

 of the hawk-fly — that it may escape the general massacre. It devotes its whole time and 

 attention to sucking aphides. Truly it has a wonderful appetite. I watched one suck for a 

 whole hour without a check, and a glorious heap of slain it left. It seemed by no means par- 

 ticular as to whether they were old or young, tender or tough, winged or not winged. 



As a check to insects, some recommended washing the Rose-stocks with soap and water ; 

 others tie some cotton-wool tightly round the stock, with the view of checking the upward 

 march of the invaders. — R. A. 



To destroy the Aphis on Rose-trees out of doors — In the " Ladies' Companion to the 

 Flower Garden," under the article Aphis, Mrs. Loudon advises to make a decoction of quassia, 

 in the proportion of an ounce of chips to a quart of water, and dip the infested branches of Roses 

 into it. This cannot be so done upon a large scale, but I have found the use of the decoction so 

 valuable that it ought to be more generally known. My mode of using it is as follows. 

 Having made in the outset a small quantity in the above proportions, and tested it as a guide 

 for my future use, I now make from two to three gallons at a time in a large iron boiler. When 

 cold, on a fine day throw it on your Rose bushes by means of a garden syringe, taking care to 

 wet the under as well as the upper surface of the leaves. In two days' time you will see thou- 

 sands of the insects adhering to the leaves, but quite dead. Then syringe the bushes with plain 

 water, using considerable force, to wash off the dead aphides. You will no doubt observe many 

 still living, as it is almost impossible to wet them all at one operation. Repeat the syringing 

 with the decoction, and afterwards with the water.
