As he came to this conclusion he sat up, rubbed his eyes, and looked round him. It was about six o'clock, and already very dusk in the wood, though the little dancing leaves of the Leeches could not make much shadow yet, for it was only April; all round the boy rose the grey straight stems of the trees, and tufts of primroses shone out whitely here and there on the ground. It was perfectly still and silent, except that a cold little wind rustled the branches, and the birds were making a few last twittering notes before they went to sleep--"a harmony," as the country folks called it. Frank got up and hurried on, for he knew that directly mother returned search would be made for him. He must get a long way on before that, and hide somewhere for the night. That side of the wood near Green Highlands was quite familiar to him, and though there were no paths, and it all looked very much alike, he knew what direction to take for the hiding-place he had in view. A town boy would soon have become confused, and perhaps have ended in finding himself at Green Highlands again, but Frank knew better than that, and he stumbled steadily along in his heavy boots, getting gradually and surely further away from home and deeper in the wood. How quiet it was, and how fast the darkness seemed to close round him! All the birds were silent soon, except that a jay sometimes startled him with its harsh sudden cry; once a rabbit rushed so quickly across his path that he almost fell on it. On and on he went at a steady jog-trot pace, looking neither to right nor left. Now, if you have ever been in a beech wood, you must remember that winter and summer the ground is covered with the old dead brown leaves that have fallen from the trees. So thick they lie, that in some places you can stand knee-deep in them, especially if there are any hollows into which they have been drifted by the wind; this particular wood was full of such hollows, some of them wide and long enough for a tall man to lie down in, and Frank knew exactly where to find them. Turning aside, therefore, at a certain clump of bushes there was the very thing he wanted--bed and hiding-place at once. It was a broad shallow pit or hollow filled quite up to the top with the red-brown beech leaves. He scooped out a place just large enough for himself, lay down in it, and carefully replaced the leaves up to his very chin. He even put a few lightly over his face, and when that was done no one would have imagined that a boy or any other living thing was hidden there. Then the solemn hours of darkness came silently on; all the creatures in the great wood slept, and even Frank in his strange leafy bed slept also, worn out with weariness.
