Agricultural Experiment Station; Agriculture -- New York (State). Fire Blight of Pears, Apples, Quinces, Etc. 165 these spurs as soon as they show the disease will prevent the bacteria from getting into the limbs (See Fig. 6). In tall trees use a ladder and also a hook on the end of a long handle. (b) Rub off with the hands, from the trunks and main limbs, all shoots and watersprouts as fast as they start. This will remove the possibility of the formation of limb and body cankers and save much work in cutting out cankers the fol- lowing season. It will not be necessary to disinfect such wounds. (c) Cut out all blighted twigs, shoots and watersprouts (Fig. 22). As indicated above, dis- infect the cut with corrosive sublimate. If a long-handled pruner is used the sponge may be attached as shown in Fig. 21, simply touching the cut surface with it as soon as the twig is removed. Remove and destroy all prunings. Always disinfect the cut or wound not the tools. If all cut surfaces are disinfected any bacteria left on them by the tools or any brought to them subsequently by insects will be destroyed. Cutting out the Blight once or twice during the season, when it has become sufficiently serious to frighten the grower, is a waste of time and an in- jury to the orchard. If it is.

One tab- let to quart of water makes a i-iooo solu- tion. To clean out cankers the wooden bucket and the can with the sponge will be found satisfactory. Wet tJie sponge in the bucket and place it in the can, which is carried at the waist by passing the wires about the body and hooking behind. The bottle tied at the belt or to a strap over the shoulder is
