Usage examples
I sent my second son, Fred Meeker, to London to learn the English methods of fighting the pest and to import some spraying machinery.
We found to our cost, however, in the course of time, that the English methods did not suit our different conditions; for while we could kill the lice, we had to use so much spraying material on the dense foliage that, in killing them, we virtually destroyed the hops.
