During the last days of August, Dr. Kellicott and myself, in studying the Squash borer, Melittia ceto, transplanted to a large breeding cage a number of roots and portions of the stems of Squash vines, on one of which was a leaf or two. The cage was filled with earth, dug up in the field, and when the vines were properly transplanted, the cage was covered with fine Swiss muslin, and placed in the Insectary. I soon noticed Siphonophora on the stumps of the vines, and before long there sprung up, from the soil in the cage, numbers of plants of Capsella bursapastoris and Nepta glechoma.
