The Apple Maggot and Potato-Rot. By F. L. Harvey. Pp. 8. This pest, of comparatively recent introduction into orchards, has been studied during two years, and Professor Harvey recommends the following means of keeping it in check, "1. Thoroughly and promptly destroy all refuse from infested fruits, apple pomace, waste about the house, etc. 2. Promptly destroy windfall apples and infested fruit. 3. Destruction should be immediate after the first of Angust, and nothing short of deep burying, burning or feeding to swine or cattle will be effective. 4. These precautions should be universally adopted. 5. The sale or importation of infested fruit should be prohibited".

In Maine the flies appear early in July and "continue to emerge from the ground for about six weeks or two months. They soon begin to deposit eggs in the early apples, which are at that time from one-half to two-thirds grown." Each female is capable of laying over 300 eggs. There is no evidence of more than one brood.
