regular in taking their meals, in the middle of the forenoon and
afternoon, that they should be destroyed only in the morning or
evening, when all are in the tent.

Another remedy is to shower the trees with Paris green in water, in
the proportion of one pound to one hundred and fifty gallons of water.
