There were also com- paratively few moths to be found later, and the egg masses of the next year's brood are correspond- ingly reduced in numbers, al- though there are still enough of these eggs upon the trees to yield a goodly crop of caterpillars next season. We tried many experiments with remedies for the American Tent Caterpillar, although but lit- tle new information was brought out. The careful use of a small amount of kerosene, a teaspoonful to a nest, in wetting the silk of the tent, was found a satisfactory way of killing the partially grown caterpillars. But great care is necessary, as, if sufficient kerosene is added to saturate the bark, the tree is injured. If the web away from the bark is lightly dampened the caterpillars come in contact with it as they pass in and out of the nest and are killed. One of the most satisfactory remedial measures for these tent caterpillars that has come to my notice related to the removal of the egg masses. In Xewfields, N. H., the Village Improvement Society offered the children in the' schools ten cents a hundred for all the egg masses or.
