These arc abundant enough, as every one who has tried to cultivate roses knows, unless the experiment has been made in some region exceptionally free from the ills to which these shrubs are heir. Bugs and worms, and flies, too, often cover the bushes, and it is impossible to give infallible directions for their extermination. One cultivator uses carbolic soap with success, while another does better with whale oil soap, and still another accomplishes wonders with tobacco smoke. All the dealers in seeds and horticultural supplies keep the soap and the oil on hand, and tobacco can be had in large quantities at a cheap rate. Perhaps as effectual a method as any is found in the combination of tobacco smoke with either of the other two agents, the washing being done either before or after the smoking. Now, the smoking, although it is very easy to talk about, has its drawbacks. If, however, it must be done, it is well to do it effectually.

We have seen a device which, so far as the production of smoke goes, is very satisfactory. A common tin box, such as dry mustard is sold in, is taken to the tinman, who cuts a hole about half an inch across in the bottom, and solders on a tapering tube, something like the nozzle of an oil can. In the cover of the box he cuts another hole, and solders on a tube flaring slightly outward, of a size to fit over the nozzle of a pair of bellows. The whole machine looks like one of the affairs which dealers in magic cockroach powders sell for the purpose of blowing the powder into cracks and crannies. The box is filled with tobacco, and a live coal inserted just under the cover. The tube is then placed on the bellows, and the latter put in operation. The result will be a smoke such as no respectable insect will endure for a moment.

It is quite practicable to smoke plants, both in-doors and out, by using a light frame covered with glazed cloth, or other reasonably smoke-proof material. This is made large enough to put bodily over the bush. The nozzle of the smoke bellows may then be introduced through a suitable aperture, and in a few minutes, or sec* onds, the smoke inside will be almost thick enough to cut with a knife. - Ex.
