sun, in ambush till a dark lady should come. The yellow tulip was a perfect weather-meter; if there was the least bit of harshness in the air, the least relic of the east wind, it remained folded. Sunshine alone was not sufficient to tempt it, but the instant there was any softness in the atmosphere open came the bell, and as if by a magic key all the bees and humble-bees of the place were unlocked, and forth they came with joyous note--not to visit the tulip, which is said to be a fatal cup of poison to them. Any one delicate would do well to have a few such flowers in spring under observation, and to go out of doors or stop in according to their indications. I think there were four species of wild bee at these early flowers, including the great bombus and the small prosopis with orange-yellow head. It is difficult to scientifically identify small insects hastily flitting without capturing them, which I object to doing, for I dislike to interfere with their harmless liberty. They have all been named and classified, and I consider it a great cruelty to destroy them again without special purpose. The pleasure is to see them alive and busy with their works, and not to keep them in a cabinet. These wild bees, particularly the smaller ones, greatly resented my watching them, just the same as birds do. If I walked by they took no heed; if I stopped or stooped to get a better view they were off instantly. Without doubt they see you, and have some idea of the meaning of your various motions. The wild bees are a constant source of interest, much more so than the hive bee, which is so extremely regular in its ways. With an explosion almost like a little bomb shot out of a flower; with an immense hum, almost startling, boom! the great bombus hurls himself up in the air from under foot; well named--boom--bombus. Is it correct or is it only a generalisation, that insects like ants and hive bees, who live in great and well-organised societies, are more free from the attacks of parasites than the comparatively solitary wild bees? Ants are, indeed, troubled with some parasites, but these do not seem to multiply very greatly, and do not seriously injure the populousness of the nest. They have enemies which seize them, but an enemy is not a parasite. On the other hand, too, they have mastered a variety of insects, and use them for their delectation and profit. Hive bees are likewise fairly free from parasites, unless, indeed, their so-called dysentery is caused by some minute microbe. These epidemics, however, are rare. Take it altogether, the hive bee appears comparatively free of parasites. Enemies they have, but that is another matter.
