Y scented, and are generally white or pale yellow, these colours being
most visible in the twilight. Aristotle long ago noticed the curious
fact that in each journey Bees confine themselves to some particular
flower. This is an economy of labour to the Bee, because she has not to
vary her course of proceeding. It is also an advantage to the plants,
because the pollen is carried from each flower to another of the same
species, and is therefore less likely to be wasted. FRUITS AND SEEDS
After the flower comes the seed, often contained in a fruit, and which
itself encloses the future plant. Fruits and seeds are adapted for
dispersion, beautifully and in various ways: some by the wind, being
either provided with a wing, as in the fruits of many trees--Sycamores,
Ash, Elms, etc.; or with a hairy crown or covering, as with Thistles,
Dandelions, Willows, Cotton plant, etc. Some seeds are carried by
animals; either as food--such as most edible fruits and seeds, acorns,

Shamrocks, etc. Our little Herb Robert throws its seeds some 25 feet.
Some seeds force themselves into the ground, as those of certain
grasses, Cranes'-bills (Erodiums), etc. Some are buried by the p
