this case, too, lost in power,--that is, in the vigor of the tree.
This is their pyramidal state.

The cows continue to browse them thus for twenty years or more,
keeping them down and compelling them to spread, until at last they
are so broad that they become their own fence, when some interior
shoot, which their foes cannot reach, darts upward with joy: for it
has not forgotten its high calling, and bears its own peculiar fruit
in triumph.

Such are the tactics by which it finally defeats its bovine foes.
Now, if you have watched the progress of a particular shrub, you
will see that it is no longer a simple pyramid or cone, but out of
its apex there rises a sprig or two, growing more lustily perchance
than an orchard-tree, since the plant now devotes the whole of its
repressed energy to these upright parts. In a short time these
become a small tree, an inverted pyramid resting on the apex of the
other, so that the whole has now the form of a vast hour-glass. The
spreading bottom, having served its purpose, finally disappears, and
the generous tree permits the now harmless cows to come in and stand
in its shade, and rub against and redden its trunk, which has grown
in spite of them, and even to taste a part of its fruit, and so
disperse the seed.

Thus the cows create their own shade and food; and the tree, its
hour-glass being inverted, lives a second life, as it were.

It is an important question with some nowadays, whether you should
trim young apple-trees as high as your nose or as high as your eyes.
The ox trims them up as high as he can reach, and that is about the
