PROTECTING PLANTS 181 certain galls that often appear on the limbs of large apple-trees, are also known to be caused by this same bacterium. The disease seems to be most serious and destructive on the raspberry, par- ticularly the Cuthbert variety. The best thing to be done when the rasp- berry patch becomes in- fested is to root out the plants and destroy them, planting a new patch with clean stock on land that has not grown ber- ries for some time. Not- withstanding the laws that have been made against the distribution of root-gall from nurs- eries, the evidence seems to show that it is not a serious disease of apples or peaches, at least not in the northeastern United States. It is not determined how far it may injure such trees. Of obvious insect injuries, there are two general types, — those wrought by insects that bite or chew their food, as the ordinary beetles and worms, and those wrought by insects that puncture the surface of the plant and derive their food by sucking the juices, as scale-insects and plant-lice.
