"In three days the web was, with incredible diligence, completed; nor could I avoid thinking that the insect seemed to exult in its new abode. It frequently traversed it round, examined the strength of every part of it, retired into its hole, and came out very frequently. The first enemy, however, it had to encounter was another and a much larger spider, which, having no web of its own, and having probably exhausted all its stock in former labors of this kind, came to invade the property of its neighbor. Soon, then, a terrible encounter ensued, in which the invader seemed to have the victory, and the laborious spider was obliged to take refuge in its hole. Upon this I perceived the victor using every art to draw the enemy from its stronghold. He seemed to go off, but quickly returned; and when he found all arts in vain, began to demolish the new web without mercy. This brought on another battle, and, contrary to my expectations, the laborious spider became conqueror, and fairly killed his antagonist. "Now, then, in peaceable possession of what was justly its own, it waited three days with the utmost patience, repairing the breaches of its web, and taking no sustenance that I could perceive. At last, however, a large blue fly fell into the snare, and struggled hard to get loose. The spider gave it leave to entangle itself as much as possible, but it seemed to be too strong for the cobweb. I must own I was greatly surprised when I saw the spider immediately sally out, and in less than a minute weave a new net round its captive, by which the motion of its wings was stopped; and when it was fairly hampered in this manner it was seized and dragged into the hole. "In this manner it lived, in a precarious state; and nature seemed to have fitted it for such a life, for upon a single fly it subsisted for more than a week. I once put a wasp into the net; but when the spider came out in order to seize it, as usual, upon perceiving what kind of an enemy it had to deal with, it instantly broke all the bands that held it fast, and contributed all that lay in its power to disengage so formidable an antagonist. When the wasp was set at liberty, I expected the spider would have set about repairing the breaches that were made in its net; but those, it seems, were irreparable; wherefore the cobweb was now entirely forsaken, and a new one begun, which was completed in the usual time. "I had now a mind to try how many cobwebs a single spider could furnish; wherefore I destroyed this, and the insect set about another. When I destroyed the other also, its whole stock seemed entirely exhausted, and it could spin no more. The arts it made use of to support itself, now deprived of its great means of subsistence, were indeed surprising. I have seen it roll up its legs like a ball, and lie motionless for hours together, but cautiously watching all the time; when a fly happened to approach sufficiently near, it would dart out all at once, and often seize its prey.
