Insects on Hot-House Plants, as Destroyed in Paris, France.
Baron Rothschild's gardener, at Paris, France, says he destroys all the troublesome insects that may be in the hot-house, by vaporizing 2 qts. of •tobacco juice in the hot-house; and he considers the remedy infallible, and also says it rarely injures the tenderest plants.
Remarks. —He does not give the strength, but I should say 4 ozs. of tobacco would be plenty for the 2 qts. of the juice, as he calls it; and I should expect the doors ought to be closed also while being done. The vaporizing being done by setting the dish over a charcoal fire, on the plan of a tinman's heater used for heating his soldering irons.
