The the study of the apple worm. egg-laying habits of the moths were studied with great care the past season, and will be observed again next summer. Among other methods used for securing an exact knowledge concerning them, was that of erecting a large cage cov- ered with cheese cloth over a ten-year- old apple tree and introducing in it a single pair of the codling moths. Be- fore doing so every leaf on the tree was carefully examined to bo sure that no eggs had already been laid.
