The rushes grew thickly along the sides, but the water was clear, and we could plainly see the black bugs she pointed out to us crawling, slowly and clumsily, over the muddy bottom.
“Those things!” said John, not a little disgusted. “I don’t think they are much. Are they tadpoles?”
“Tadpoles!” I echoed. “Why, whoever saw tadpoles with six legs and no tail?”
“The absence of a tail is very convincing,” laughed Aunt Bessie. “They are certainly not tadpoles. Now watch them closely, please, and tell me all about them.”
“They are abominably ugly. That is one thing,” broke in John. “They look black, and have six legs. But how funny their skin is. More like a crust, or lots of crusts laid one on the other. They are about the stupidest things I ever saw. They seem to do nothing but crawl over that mud and—Hello! they aren’t so stupid, after all. Did you see that fellow snatch a poor fly and gobble him up quicker than you could say Jack Robinson? And there’s another taken a mosquito just as quick. I’ll take back what I said about the slow business. But really, Auntie, do you think them very interesting?”
“I’ll ask you that question when you have learned something more about them,” was her answer. “Tell me now what you think of that Dragon-fly darting over the water?”
“Oh, he is a beauty,” we answered in a breath. “But please let us hear something about those things down there.”
“Not to-day, boys. I wish you to see something for yourselves first. Watch here for a few days and your patience will be rewarded, I promise you. Then I will have a story to tell you.”
I knew that Auntie never spoke without reason, so John and I kept a close watch on those bugs. For two days nothing happened. The old things just crawled over the mud or ate flies and mosquitoes, as usual.
But the third day one big fellow decided to try something new. It was nothing less than to creep up the stem of one of the rushes. I suppose it was hard work, for he took a long time to get to the surface of the water. Here he stopped a while and then seemed to make up his mind to go further. Soon he was quite out of the water and could breathe all the air and sunshine he wished. I believe he did not like it very well. He seemed so restless and uneasy. I was expecting to see him go back, when I heard John cry out:
