This is an article largely used to kill the brown and white scale. The latter is much the worst to contend with. To ten gallons of water add a half pint of the oil. If the water is at a temperature of 100 degrees, so much the better. Large palms and other plants can be syringed and in half an hour be given a good syringing of clear water, when most of the scale will be destroyed. Small palms can be dipped or immersed entirely in the water, excepting, of course, the ball of earth, and shortly afterwards syringed with clear water. That is doing it most effectually.

Palms received from Europe are often infested with this white scale and should be thoroughly cleaned before placing among your other stock.
