Under the willow shade, and from one of the branches, I had hung a miniature "belfry," containing a tiny brass bell, and had led the string into the water, letting it go down to a considerable depth. At first, I tied a bait at intervals upon the line, and the sticklebacks, of course, seized upon it, and thus rang the bell. Generally the ringing was done in a very grave and proper way, although sometimes, when the bait was too tightly tied, the quick peals sounded like a call to a fire. I kept up this system of baiting the string for about a week, until I thought they understood it, and then replaced the worms by bits of stone. As I expected, the next morning, as I looked through the grass and down into the water, tinkle! tinkle! rang the bell, and I knew my little friends were saying, "Good-morning!" and expected a breakfast. You may be sure they got it. I put my hand down, and up they came, and got one worm apiece; and as I raised my hand, down they rushed, and away went the bell, in an uproarious peal, that must have startled the whole neighborhood. I was quick to respond, and they soon learned to ring the bell before coming to the surface; in fact, if they saw me pass, I always heard their welcome greeting. But to return to the minnows. I generally fed them first, about twenty feet up the bank; but one morning I found one or two had followed me down to the residence of the stickleback family. They met with a rude reception, however, and, to avoid making trouble, the next day I went to the willow first. But no sooner had the bell begun to ring, than I saw a lot of ripples coming down, and in a second the two factions were in mortal combat. The sticklebacks were fighting not only for breakfast, but for their nests, which were near by; and they made sad work of the poor minnows, who, though smart in some things, did not know when they were whipped, and so kept up the fight, though losing one of their number nearly every morning. The bell now and then rang violently, but I fear it was only sounding an appeal from a voracious stickleback whose appetite had got the better of his rage.
