beneficial result. We noted also that the application of tobacco, 
whether in the form of a decoction or the cut leaves, seemed to 
stimulate the growth of the plants. 
Air-slacked lime dusted over the plants while wet proved unques- 
tionably beneficial, and in dry weather its effects are quite lasting. 
Among the applications that proved valueless, we mention kerosene 
mixed with sand at the rate of an ounce of the former to a pound of 
the latter; Buhach powder mixed with alcohol, diluted with differ- 
ent proportions of water and soluble phenyle, dissolved in variou 
proportions of water. 
We have frequently noted that plants of cabbage, radish, etc., 
grown in the cold frame are scarcely injured by the flea beetle: As 
an experiment we planted a small plat of radishes in a frame made 
of boards a foot wide. The plants were very little injured by the 
beetle. We noted that in one case, where the leaves of a plant 
reached over the edge of the frame, this plant had many beetles upon 
it, while the others were almost entirely free from them. This leads 
us to recommend, growing so far as practicable, all plants injured by — 
this pest in a frame made of wide boards. It appears that this in- 
sect, though very agile, does not jump very high, and hence may be 
kept away from plants in this manner. | 
The Radish Fly. 
The larva of the radish fly, Anthomyia radicum, proves very in- 
jurious to the roots of radishes when grown on the heavy soil of our 
garden. None of the applications used for the flea beetle had any 
perceptible effect in preventing its injuries. We found that bisul 
phide of carbon applied to the soil about the roots of the plants de- 
stroyed the maggots that had not yet entered the roots, but it had 
no perceptible effect upon those within. The use of this liquid as 
an insecticide is accompanied by so many disadvantages that we 
must at present consider it of little value. 
We obtained very satisfactory results with the use of coal ashes as 
a preventive of injury from the radish fly, which are noted in detail 
in treating of the radish. 
Tue Srrreep CucumBER BEETLE. 
But one application seemed beneficial in preventing the ‘njuries 
of the striped cucumber beetle, Diabrotica vittata. This was Paris 
green mixed with water at the rate of half a tea-spoonful to two gal- 
lons, and the mixture applied with care to both sides of the leaves. 
When applied only to the upper sides of the leaves it proved less 
efficacious, as the beetles remain much of the time during sunny 
weather upon the lower sides of the leaves and upon the stems. 
Our efforts to repel this insect by powerful odors proved useless. 
We dipped corn cobs in coal tar, and placed them among the plants 
of a hill of squashes. Wethen covered the hill with a plant protector, 
formed of mosquito netting tacked upon a frame, beneath which we
