extent by the same methods used for
killing phylloxera in vineyards, by

The method is very simple. A la.
borer armed with an iron rod, or ar.
iron tipped stake makes hoe in the
dirt next an infested plant, pours in
an ounce or so of carbon bisulphide
covers the hole with scrape, Of his
heel, and passes on to the next plant
