Wind speed degrees of motion

The different degrees of motion of wind next excite our attention; and it seems almost superfluous to observe, that it varies in gradation from the mildest zephyr, which plays upon the leaves of plants, gently undulating them, to the furious tempest, calculated to inspire horror in the breast of the most callous. It is also a remarkable fact, that violent currents of air pass along, as it were, within a line, without sensibly agitating that beyond them. An instance of the fury of the wind being bounded 'by a line' occurs in the hurricane of America; where its devastating course is often accurately marked in the forests for a great extent in one direction.
