We believe the Gardeners' Monthly was the first to show that one of the cheapest and best modes of destroying insects on pot plants was to invert the pot and dip the plant for a few seconds in water warmed to 130.

It is, after all these many years, the best plan for destroying insects, unless we have to deal with plants on a very large scale. We notice that the Garten Zeitung in referring to the plan, says that the azalea will stand 133° without injury. We usually heat the water pretty well and pour in cold till 130 is reached.
