All the branches of trees at every stage of their height, united to-gether, are equal to the thickness of their trunk.

The thickness of a branch is never diminished in the space there is between one leaf and another except by as much as the thickness of the eye that is above the leaf, and this thickness is lacking in the branch up to the next leaf.

The beginning of the branch will always have the central line of its thickness taking its direction by the central line of the plant.

Fancy cutting down all those beautiful trees...to make pulp for those bloody newspapers, and calling it civilisation.

There's whistling coming out of a forest somehow; there's an entire dead species of tree right there in front of you, and not just a few trees, it goes for miles and miles. So, with that background, and then knowing what's going on in the world . . . I don't like to dwell on it much, but I think everybody's terrified.

This old world keeps spinnin' round; It's a wonder tall trees ain't layin' down.
