Brand New Book ***** Print on Demand *****.Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, 1878 Boring] of Cowl/as from the Outside by Iloncy-liees. - i ir. l iiomas referred to the practice of the humble-bee in boring the corolla instead of entering by the mouth, eten when there might he no great difficulty in doing so. A few years ago it was not noticed that any flowers were despoiled of their sweets in this extraneous way, but it was now known that the list of plants so treated was very large, and the humble-bee in America had already lost considerable of its reputation as an agent in the cross fertilization of owers. He had carefully watched the honey-bee for some years, but could never feel sure that it also bored the corollas in the same way, for though he had often seen them working from the outside, he suspected that they used the holes made by the humble-bee. Mr. Ryder, at one of our meet ings, had insisted that the honeybee did actually work occasion ally ih this way, and Mr. Meehan said he was thus led to go over the subject again, proving Mr. {yder to be right. Late in the autumn, long after most other owers were gone, and with no humble-bees about, scarlet sages, Saluta splendens, for neatly a week together, received the sole attention of the honey-bees, which worked among the owers in great numbers, in all boring the corollas near the base from the outside. In connection with this fact, he said that among the scarlet sages were a large number of the pure white variety, but the bees visited them precisely as they did the scarlets, going to either indiscriminately. As bees usually contrive to work on one kind of ower only so long as there were plenty of that one kind, the fact of their working on these two colors at once showed that they did not make use of color only as a guide to the owers, but that they had intelligence enough to know the Saleia splemlens as well as we would, by experience, no matter under what color the species might be represented; and the experiments we read of, in which the bees failed to make use of a fresh ower when its corolla was taken away, merely showed that the bee was not act ing from an instinctive attraction by color, but had been deceived into the idea that the ower had faded away. Insects had evi dently not only instinct, but were able to exercise a judgment created by experience. In a recent number of Nature, he said it was on record that a day moth, a Macroglossum, made an attempt to extract honey from the artificial owers on a lady s bonnet, but it was so well able to profit by experience as not to make the attempt a second time.
