Thus it was that he learned that there were two ways of flying, one without noise and the other with the thunder of whirring wings. Also he learned that there was a time for each. When he knew himself to be alone and suddenly detected the approach of an enemy, he often would launch himself into the air on silent wings before his presence had been discovered. But when others of his family were near, he would burst into the air with all the noise he could make as a warning to others. Also, it sometimes startled and confused the enemy.

Thunderer had taught him the trick one day when Reddy Fox had stolen, unseen by Tommy, almost within jumping distance. Thunderer had seen him, and purposely had waited until Reddy was just gathering himself to spring on the unsuspecting Tommy. Then with a splendid roar of his stout wings Thunderer had risen just to one side of the fox, so startling him and distracting his attention that Tommy had had ample time to whir up in his turn, to the discomfiture of Reddy Fox.

So, when the fall came, Tommy was big from good living, and filled with the knowledge that makes for long life among grouse. He knew the best scratching-grounds, the choicest feeding-places according to the month, every bramble-tangle and every brush-pile, the place for the warmest sun-bath, and the trees which afforded the safest and most comfortable roosting places at night.

He knew the ways and the favorite hunting-grounds of every fox, and weasel, and skunk, and coon of the neighborhood, and how to avoid them. He knew when it was safest to lie low and trust to the protective coloring of his feathers, and when it was best to roar away on thundering wings.

The days grew crisp and shorter. The maples turned red and yellow, and soon the woods were filled with fluttering leaves and the trees began to grow bare. It was then that old Thunderer warned Tommy that the season of greatest danger was at hand. Somehow, in the confidence of his strength and the joy of the splendid tide of life surging through him, he didn’t fear this unknown danger as he had when as a little fellow he had first heard of it. Then one day, quite unexpectedly, he faced it.

He and Thunderer had been resting quietly in a bramble-tangle on the very edge of the Green Forest, when suddenly there was the rustle of padded feet in the leaves just outside the brambles. Looking out, Tommy saw what at first he took to be a strange and very large kind of fox, and he prepared to fly.

“Not yet! Not yet!” warned Thunderer. “That is a dog and he will not harm us. But to fly now might be to go straight into that greatest danger, of which I had told you. That is the mistake young grouse often make, flying before they know just where the danger is. Watch until you see the two-legged creature with the fire-stick, then follow me and do just as I do.”

The dog was very near now. In fact, he had his nose in the brambles and was standing as still as if turned to stone, one of his fore feet lifted and pointing straight at them. No one moved. Presently Tommy heard heavy steps, and, looking through the brambles, saw the great two-legged creature of whom Thunderer had told him.

“Now!” cried Thunderer. “Do as I do!” With a great roar of wings he burst out of the tangle on the opposite side from where the hunter was, and flying low, so as to keep the brambles between himself and the hunter, swerved sharply to the left to put a tree between them, and then flew like a bullet straight into the Green Forest where the trees were thickest, skillfully dodging the great trunks, and at last at a safe distance sailing up over the tops to take to the ground on the other side of a hill and there run swiftly for a way.

Tommy followed closely, doing exactly as Thunderer did. Even as he swerved behind the first tree, he heard a terrible double roar behind him and the sharp whistle of things which cut through the leaves around him and struck the tree behind him. One even nipped a brown feather from his back. He was terribly frightened, but he was unhurt as he joined Thunderer behind the hill.
