September 1.
See how artfully the seed of a cherry is placed in order that a bird may be compelled to transport it. It is placed in the very midst of a tempting pericarp, so that the creature that would devour a cherry must take a stone into its mouth. The bird is bribed with the pericarp to take the stone with it and do this little service for Nature. Thus a bird's wing is added to the cherry-stone which was wingless, and it does not wait for winds to transport it.

Cherries are especially birds' food, and the consequence is that cherries not only grow here but there. Many kinds are called birds' cherry, and unless we plant the seeds occasionally, I shall think the birds have the best right to them.
H. D. Thoreau, Journal, September 1, 1860
See The Succession of Forest Trees ("As for the heavy seeds and nuts which are not furnished with wings, the notion is still a very common one that, when the trees which bear these spring up where none of their kind were noticed before, they have come from seeds or other principles spontaneously generated there in an unusual manner, or which have lain dormant in the soil for centuries, or perhaps been called into activity by the heat of a burning. I do not believe these assertions, and I will state some of the ways in which, according to my observation, such forests are planted and raised. Every one of these seeds, too, will be found to be winged or legged in another fashion.
Surely it is not wonderful that cherry-trees of all kinds are widely dispersed, since their fruit is well known to be the favorite food of various birds. Many kinds are called bird-cherries, and they appropriate many more kinds, which are not so called. Eating cherries is a bird like employment, and unless we disperse the seeds occasionally, as they do, I shall think that the birds have the best right to them.
See how artfully the seed of a cherry is placed in order that a bird may be compelled to transport it — -in the very midst of a tempting pericarp, so that the creature that would devour this must commonly take the stone also into its mouth or bill. If you ever ate a cherry and did not make two bites of it, you must have perceived it — right in the centre of the luscious morsel, a large earthy residuum left on the tongue.
We thus take into our mouths cherry-stones as big as peas, a dozen at once, for Nature can persuade us to do almost anything when she would compass her ends. Some wild men and children instinctively swallow these, as the birds do when in a hurry, it being the shortest way to get rid of them.
Thus, though these seeds are not provided with vegetable wings, Nature has impelled the thrush tribe to take them into their bills and fly away with them; and they are winged in another sense, and more effectually than the seeds of pines, for these are carried even against the wind. The consequence is, that cherry-trees grow not only here but there. The same is true of a great many other seeds.")

See how artfully the seed of a cherry is placed . . .Thus a bird's wing is added to the cherry-stone which was wingless, and it does not wait for winds to transport it. See September 1, 1859 ("The cherry-birds and robins seem to know the locality of every wild cherry in the town."):See also July 14, 1856 ("While drinking at Assabet Spring in woods, noticed a cherry-stone on the bottom. A bird that came to drink must have brought it half a mile. So the tree gets planted!"); February 4, 1856. ("I have often wondered how red cedars could have sprung up in some pastures which I knew to be miles distant from the nearest fruit-bearing cedar, but it now occurs to me that these and barberries, etc., may be planted by the crows, and probably other birds.") see also September 21, 1860 ("I suspect that . . . those [seeds] the wind takes are less generally the food of birds and quadrupeds than the heavier and wingless seeds."); October 16, 1860 (Looking from a hilltop, I observe that pines, white birches, red maples, alders, etc., often grow in more or less regular rounded or oval or conical patches, while oaks, chestnuts, hickories, etc., simply form woods of greater or less extent, whether by themselves or mixed, and do not naturally spring up in an oval form. This is a consequence of the different manner in which trees which have winged seeds and those which have not are planted")
