Did you ever go out on a summer morning, when there had been a heavy dew the night before and see an entire field literally covered with a wonderful fine mesh, that sparkled and glistened in the sunlight until it looked like fairy-land? Many of the tops of the taller grasses were bound together, ever so delicately, by a wonderful shimmering something, which you children called cobwebs. In the summer-time you will see these delicate shimmering garments on the tall weeds, and on the walls along the roadside.
Did you ever stop to think that this is all the work of the spiders and the fields are beautiful this morning because a million spiders wanted to travel, catch flies, or amuse themselves?
Yet this is the case. The spider is the original balloonist. He also knows the use of the parachute and he can disport himself in the air more gracefully than any bird, and as airily as thistle-down. In fact his ballooning is a sort of thistle-down performance. For he has discovered the secret of all the lighter than air flying machines.
