When the aphis is located on the stalk or leaf of a plant it is furnished with means to pierce the surface and extract the juices essential to the formation of the plant, thereby preventing vigorous growth and a full development. This idea is too apt to be associated with the bee when she visits the flower, as if she was armed with a spear, to pierce bark or stem and rob it of its nourishment. Her real structure is lost sight of, or perhaps never known; her slender brush-like tongue folded closely under her neck, and seldom seen except when in use, is not fitted to pierce the most delicate substance; all that it can be used for is to sweep or lick up the nectar as it exudes from the pores of the flower, secreted, it would seem, for no other purpose but to attract her--while there she obtains nothing but what nature has provided for her and given her the means of obtaining, and the most delicate petal receives no injury. During an excursion the bee seldom visits more than a single species of flower; were it otherwise, and all kinds of flowers were visited promiscuously, by fertilizing one species with the pollen from another, the vegetable kingdom would be very likely to get into confusion. Writers, when noticing the peculiarity of instinct governing the bee here, cannot be content always, but must add other marvels. They follow this trait into the hive, and make her store every kind by itself there. Relative to honey it is not an easy matter to be positive; but pollen is of a variety of colors, generally yellow, yet sometimes pale-green, and reddish or dark-brown. Now I think a little patient inspection would have satisfied any one that two kinds _are_ sometimes packed in one cell, and prevented the assertion to the contrary. I will admit that two colors are seldom found packed together, but sometimes will be. I have thus found it, and it has entirely ruined that theory for me. A TEST FOR THE PRESENCE OF QUEEN DOUBTED.
