. Handbook of nature-study for teachers and parents, based on the Cornell nature-study leaflets. Nature study. Wild-Flower Study 541 pairs; if one pair points east and west, the pair above and the pair below point north and south. The leaf is beautiful in every particular; it has a dark green upper surface, diversified with veins that join in scallops near the border; it is soft to the touch on the upper surface, and is velvety below. The lens reveals that the white under surface, or the nap of the velvet, is a cover of fine white hairs. The flower of the milkweed is too complicated for little folks even to try to understand; but for the pupils of the seventh and eighth grades it will prove an interesting subject for investigation, if they study it with the help of a lens. In examining the globular bud, we see the five hairy sepals, which are later hidden by the five long, pinkish green petals which bend back around the stem. When we look into the flower, we see five little cornucopias—which are really horns of plenty, since they are filled with nectar; from the center of each is a little, fleshy tongue, with its curved point resting on the disk at the center of the flower. Between each two of these nectar-horns can be seen the white bordered opening of a long pocket—like a dress-pocket—at the upper end of the opening of which is a black dot. Slip a needle into the pocket opening until it pushes against the black dot, and out pops a pair of yellow saddle-bags, each attached to the black dot which joins them. These are the pollen-bags, and each was borne in a sac, shaped like a vest-pocket, one lying either side of the upper end of the long pocket. These pollen-bags are sticky, and they contract so as to close over the feet of the visiting bee. Since the stem of the flower cluster droops and each flower pedicel droops, the bee is obliged to cling, hanging back down, while get- ting the nectar, and has to turn about as if on a pivot in order to thrust her tongue
