Objects in Motion.-A scene, however beautiful in itself, will soon lose its interest, unless it is enlivened by moving objects; and, from the shape of the ground near most houses, there is another material use in having cattle to feed the lawn in view of the windows. The eye forms a very inaccurate judgment of extent, especially in looking down a hill, unless there be some standard by which it can be measured; bushes and trees are of such various sizes, that it is impossible to use them as a measure of distance; but the size of a horse, a sheep, or a cow, varies so little, and is so familiar to us, that we immediately judge of their distance from their apparent diminution, according to the distance at which they are placed; and as they occasionally change their situation, they break that surface over which the eye passes, without observing it, to the first object it meets to rest upon.
