In order to make it clear I have drawn a progressive series of pictures which hardly require description. The flowers are visited by small bees, butterflies, and other insects. At the left is an insect just alighting on a clump of the blossoms of the high-anther form indicated below it. The black probe represents the insect's tongue, which, as it seeks the nectar at the bottom of the tube, gets dusted at its thickened top with the pollen from the anthers. We next see the insect flying away, the probe beneath indicating the condition of its tongue. It next alights on clump No. 2, in which the flowers happen to be of the high-stigma form, as shown below. The tongue now being inserted, brings the pollen against the high stigma, and fertilizes the flower, while at the same time its tip comes in contact with the low anthers, and gets pollen from them. We next see the insect flying to clump No. 3, the condition of its tongue being shown below. Clump No. 3 happens to be of the first low-stigma form of flowers, and as the tongue is inserted the pollen at its tip is carried directly to the low stigma, and _this_ flower is fertilized from the pollen from the anthers on the same level in the previous flower. And thus the riddle is solved by the insect. From clump to clump he flies, and through his help each one of the pale blue blooms is sure to get its food, each flower fertilized by the pollen of another. [Illustration: 1st Clump.--Flower enlarged. Insect's Tongue inserted. Pollen high on Insect's Tongue after withdrawal from Blossom. 2d Clump.--Flower enlarged. Pollen thrust against high Stigma at top and touching Pollen below. Pollen at Base of Insect's Tongue after withdrawal from Blossom. 3d Clump.--Flower enlarged. Pollen thrust against low Stigma.] Another beautiful provision is seen in the difference in size of the pollen-grain of the two flowers, those of the high anthers being much larger than those from the lower anthers. These larger grains are intended for the high stigma, which they are sure of reaching, while those of smaller size, on the top of the tongue, which should happen to be wiped off on the high stigma, are too small to be effective for fertilization. Luck In Clovers Under one guise or another the fickle goddess Fortuna would seem to have established her infallible interpreters or mediators. The lovelorn maiden with the daisy, its petals falling beneath her questioning finger-tips to the alternate refrain, "He loves me. He loves me not," is a sacrificial episode in the life of the daisy wherever it grows.
