Nobody can truthfully say that the Sticklebacks are not good fathers. There are no other fish fathers who work so hard for their children as the Sticklebacks do. As to the Stickleback Mothers—well, that is different.
This particular Stickleback Father had lived, ever since he had left the nest, with a little company of his friends in a quiet place near the edge of the pond. Sometimes, when they tired of staying quietly at home, they had made short journeys up a brook that emptied into the pond. It was a brook that flowed gently over an even bed, else they would never have gone there, for Sticklebacks like quiet waters. When they swam in this little stream, they met the Brook Trout, who were much larger than they, and who were the most important people there.
Now this Stickleback was a year old and knew much more than he did the summer before. When the alder tassels and pussy willows hung over the edge of the pond in the spring-time, he began to think seriously of life. He was no longer really young, and the days were past in which he was contented to just swim and eat and sleep. It was time he should build a home and raise a family if he wanted to ever be a grandfather. He had a few relatives who were great-grandfathers, and one who was a great-great-grandfather. That does not often happen, because to be a Stickleback Great-great-grandfather, one must be four years old, and few Sticklebacks live to that age.
As he began to think about these things, he left the company of his friends and went to live by himself. He chose a place near the edge of the pond to be his home; and he brushed the pond-bottom there with his tail until he had swept away all the loose sticks and broken shells. He told some Pond Snails, who were there, that they must move away because he wanted the place. At first they didn't want to go, but when they saw how fierce he looked, they thought about it again and decided that perhaps there were other places which would suit them quite as well—indeed, they might find one that they liked even better. Besides, as one of them said to his brother, they had to remember that in ponds it is always right for the weak people to give up to the strong people.
"It will take us quite a while to move," they said to him, "for you know we cannot hurry, but we will begin at once."
All the rest of that day each Snail was lengthening and shortening his one foot, which was his only way of walking. You can see how slow that must be, for a Snail cannot lift his foot from one place and put it down in another, or he would have nothing to stand on while he was lifting it. This was a very hard day for them, yet they were cheerful and made the best of it.
"Well," said one, as he stopped to rest his foot, "I'm glad we don't have to build a home when we do find the right place. How I pity people who have to do that!"
"Yes," said his brother. "There are not many so sure of their homes as we. And what people want of so much room, I can't understand! A Muskrat told me he wanted room to turn around in his house. I don't see what use there is in turning round, do you?"
"No," answered the other Snail, beginning to walk again. "It is just one of his silly ideas. My shell is big enough to let me draw in my whole body, and that is house room enough for any person!"
The Stickleback had not meant to look fierce at the Pond Snails. He had done so because he couldn't help it. All his fins were bristling with sharp points of bone, and he had extra bone-points sticking out of his back, besides wearing a great many of his flat bones on the outside. All his family had these extra bones, and that was why they were called Sticklebacks. They were a brave family and not afraid of many things, although they were so small. There came a time when the Stickleback Father wanted to look fierce, but that was later. Now he went to work to build his nest.
