PURSUING THE PARASITE
A strange way of dealing with the parasites of fruit trees has been found by the U.S. Board of Agriculture. It recommends shooting them. A gun has been invented to shoot at a parasite-infected tree with a wad of cotton. The cotton is saturated with an insect, or parasite-killing, powder. On its path the wad breaks up at the right moment, scattering its poison in a cloud on the tree, its twigs and leaves. * The advantage of the invention is that the marksman can bombard the tree, but is himself well removed from the dangerous dust he spreads.
