It was really something more than a new experience—this first mouthful of food—for it marked a turning-point in his career. Up to this time he had lived entirely on the provisions which his parents had left him, but henceforth he was independent and could take care of himself. He was no longer an embryo; he was a real fish, a genuine Salvelinus fontinalis, as carnivorous as the biggest and fiercest of all his relations. The cleft in his breast might close up now, and the last remnant of his yolk-sac vanish forever. He was done with it. He had graduated from the nursery, and had found his place on the battle-field of life.

It must be admitted, however, that he did not look much like a mature trout, even now. He was less than three-quarters of an inch long, and his big head, bulging eyes, and capacious mouth were out of all proportion to his small and feeble body. But time and food were all that was needed to set these matters right; and now that he had learned how, he set to work and did his level best. I should be afraid to guess how many tiny water-creatures, insects and larvæ and crustaceæ, found their way down his throat, but it is pretty safe to say that he often ate more than his own weight in a single day. And so he grew in size and strength and symmetry, and from being a quiet, languid baby, always hiding in dark corners, and attending strictly to his own affairs, he became one of the liveliest and most inquisitive little fishes in all the stream. To a certain extent he developed a fondness for travelling, and in company with other troutlets of his own age and size he often journeyed from place to place in search of new surroundings and new things to eat. In fly-time he found a bountiful food-supply in the mosquitoes and black-flies that swarmed over the stream, and it was fun to see him leap from the water, catch one of them in his mouth, and drop back with a triumphant little splash. It wasn't really very considerate in him to prey on those biting, stinging flies, for in after years they would be his best defenders against anglers and fishermen, but consideration doesn't seem to be one of the strong points in a brook trout's character.

It would take too long to tell of all his youthful doings during the next year, and of all his narrow escapes, and the many tight places that he got into and out of. It was a wonder that he ever pulled through at all, but I suppose it is necessary that a few trout should grow up, for, if they didn't, who would there be to eat the little ones?

Once a kingfisher dived for him, missed him by a hair's-breadth, and flew back, scolding and chattering, to his perch on an old stub that leaned far out over the water. And once he had a horrible vision of an immense loon close behind him, with long neck stretched out, and huge bill just ready to make the fatal grab. He dodged and got away, but it frightened him about as badly as anything can frighten a creature with no more nerves than a fish. And many other such adventures he had—too many to enumerate. However, I don't think they ever troubled him very much except for the moment. He grew more wary, no doubt, but he didn't do much worrying. Somehow or other he always escaped by the skin of his teeth, and the next spring he was swallowing the new crop of young fry with as little concern as his older relations had shown in trying to swallow him. So far he seemed to be one of the few who are foreordained to eat and not be eaten, though it was more than likely that in the end he, too, would die a violent death.

When he was about a year and a half old he noticed that all the larger trout in the stream were gathering in places where the water was shallow, the bottom pebbly, and the current rapid; and that they acted as if they thought they had very important business on hand. He wanted to do as the others did, and so it happened that he went back again to the gravelly shallow where the air-bubbles had first found him. By this time he was about as large as your finger, or possibly a trifle larger, and he had all the bumptiousness of youth and was somewhat given to pushing himself in where he wasn't wanted.

The male trout were the first to arrive, and they promptly set to work to prepare nests for their mates, who were expected a little later. It was a simple process. All they did was to shove the gravel aside with their noses and fins and tails, and then fan the sediment away until they had made nice, clean little hollows in the bed of the stream; but there was a good deal of excitement and jealousy over it, and every little while they had to stop and have a scrap. The biggest and strongest always wanted the best places, and if they happened to take a fancy for a location occupied by a smaller and weaker fish, they drove him out without ceremony and took possession by right of the conqueror. For the most part their fighting seemed rather tame, for they did little more than butt each other in the ribs with their noses, but once in a while they really got their dander up and bit quite savagely. And when the lady trout came to inspect the nests that had been prepared for them, then times were livelier than ever, and the jealousy and rivalry ran very high, indeed.

Of course our Trout was too young to bear a very prominent part in these proceedings, but he and some companions of about his own age skirmished around the edges of the nesting grounds, and seemed to take a wicked delight in teasing the old males and running away just in time to escape punishment. And when the nests began to be put to practical use, the yearlings were very much in evidence. Strictly fresh eggs are as good eating down under the water as they are on land, and, partly on this account, and partly because direct sunshine is considered very injurious to them, the mothers always covered them with gravel as quickly as possible. But in spite of the best of care the current was constantly catching some of them and sweeping them away, and our young friend would creep up as near as he dared, and whenever one of the yellow-brown balls came his way he would gobble it down with as little remorse as he had felt for his first larva. Now and then an irate father would turn upon him fiercely and chase him off, but in a few minutes he would be back again, watching for eggs as eagerly as ever. Once, indeed, he had a rather close call, for the biggest old male in all the stream came after him with mouth open as if he would swallow him whole, as he could very easily have done. Our friend was almost caught when the big fellow happened to glance back and saw another trout coming to visit his wife, and promptly abandoned the chase and went home to see about it.

A year later our Trout went again to the gravelly shallow, and this time, being six inches long and about thirty months old, he decided to make a nest of his own. He did so, and had just induced a most beautiful young fish of the other sex to come and examine it, with a view to matrimony, when that same big bully appeared on the scene, promptly turned him out of house and home, and began courting the beautiful young creature himself. It was very exasperating, not to say humiliating, but it was the sort of thing that one must expect when one is only a two-year-old.

The next year he had better luck. As another summer passed away, and the cooler weather came on, he arrayed himself in his wedding finery, and it almost seemed as if he had stolen some of the colors of the swamp maples, in their gay fall dress, and was using them to deck himself out and make a brave display. In later years he was larger and heavier, but I don't think he was ever much handsomer than he was in that fourth autumn of his life. His back was a dark, dusky, olive-green, with mottlings that were still darker and duskier. His sides were lighter—in some places almost golden yellow; and scattered irregularly over them were the small, bright carmine spots that gave him one of his aliases, the "Speckled Trout." Beneath he was usually of a pale cream color, but now that he had put on his best clothes his vest was bright orange, and some of his fins were variegated with red and white, while others were a fiery yellow. He was covered all over with a suit of armor made of thousands and thousands of tiny scales, so small and fine that the eye could hardly separate them, and from the bony shoulder-girdle just behind his gills a raised line, dark and slightly waving, ran back to his tail, like the sheer-line of a ship. There were other fishes that were more slender and more finely modelled than he, and possibly more graceful, but in him there was something besides beauty—something that told of power and speed and doggedness. He was like a man-o'-war dressed out in all her bunting for some great gala occasion, but still showing her grim, heavy outlines beneath her decorations. His broad mouth opened clear back under his eyes, and was armed with rows of backward-pointing teeth, so sharp and strong that when they once fastened themselves upon a smaller fish they never let him go again. The only way out from between those jaws was down his throat. His eyes were large and bright, and were set well apart; and the bulge of his forehead between them hinted at more brains than are allotted to some of the people of the stream. Altogether, he was a most gallant and knightly little fish, and it would certainly have been a pity if he hadn't found a mate.
