* * * “The leaves employed by the leaf-cutter, are materials of somewhat stubborn texture, those sometimes of the mountain ash, and birch, as well as the rose, herein enhancing the skill of their employer. It would seem, however, that pliability and thinness are qualities somewhat regarded, and most wonderfully discerned by the little artist in question; for we have noticed in more than one summer, the smooth, delicate, tender leaves of a dark variety of China rose, almost scolloped by the circles and ovals of her excision, while the foliage of the “cabbage” close by, has been left untouched, as if too coarse and common for her purpose.”—_Acheta Domestica._ Reaumur relates that a gardener at Rouen, once chancing to dig up the nest of a leaf-cutter bee, was so utterly amazed with the singular skill of the contrivance that he was terrified, and hastened with it to the priest of the parish, believing it to be nothing less than the work of witchcraft. Monsieur le Curé, it appears, had something of the same suspicions; he advised the man to carry the nest to Paris; the gardener, however, took it first to a distinguished Naturalist living at Rouen, who relieved the poor fellow’s mind by opening one of the cases and showing him the grub within. We learn that there are several leaf-cutting or upholsterer bees, in the United States, although it is not probable that either is precisely similar to that alluded to by Mr. Knapp, and the author of Acheta Domestica.
