Here then stands the beech-tree, in all its dignity and fair proportions, its firm trunk based in the earth, but with no knarled roots upheaving the soil around, and making it unsightly. When the celebrated Smeaton pondered within himself concerning the possibility of constructing a building on the Eddystone rock, which might resist the tremendous violence of contending seas, which had swept away the previous erections of Winstanley and Rudyerd, and left not a stone remaining; seas which dash at least two hundred feet above the rock, and the sound of whose deafening surges resemble the continuous roar of thunder, his thoughts involuntarily turned towards the oak. He considered its large swelling base, which becomes reduced to one third, occasionally to one half of its original dimensions, by a gradual and upward tapering of the living shaft, and it appeared to him that a building might be erected on the model of the oak, that would be fully able to resist the action of external violence. Thus thinking, he projected the light-house of Eddystone, which soon proved, amid the tremendous fury of contending elements, that he had not erred in taking nature for his guide. A beech or elm might have suggested the same thought, for in the trunk of every forest-tree the material is so disposed that the greater portion pertains to the base of the column; that part, especially, which rises from the root is thickest, and why is this? not only because a tapering column is far more beautiful than one of equal girth, but because the disturbing force at the top, acts more powerfully on the lower sections, than on the higher. It is needful that the base of the column should be strengthened, and it is equally unnecessary that the top should be of the same thickness as the base. Two purposes are consequently answered. The tree is rendered stronger and more elegant, and a certain portion of material is given to one part, without weakening the other. A tree is, therefore, equally adapted by its construction to resist the fury of the tempest, of that unseen, yet mighty force which comes against it, when the fierce northern blast howls through the forest; as also the load of snow which often presses heavily upon its topmost branches.
