But when nurse got back to Firgrove, Darby and Joan were still absent; so, giving Eric in charge to Mary the cook, she sped up the hill again herself, flying as fast as fear and excitement could urge her, and reached the farm, panting and breathless, just when Mr. Grey and his head man, Tom Brook, were putting on their coats and preparing to leave the barn for the night.

Until almost midnight the two men tramped hither and thither through the labyrinths of Copsley Wood, carrying the stable lantern to give them light, armed with stout sticks with which to poke among the dense undergrowth of laurel, holly, and hazel that formed such a close cover for the game of various sorts with which the wood was so thickly populated. Now and then from her form amid the withered fern a frightened hare leaped among their very feet. Startled rabbits scurried here and there over the soft moss and rustling leaves. The cry of a night-bird from time to time broke the intense stillness of the lonesome place, while more than once they were alarmed by a soft something that brushed their face, as a big, downy white owl passed them by in search of its prey. In a dell hidden in the very heart of the wood they came upon what apparently had been the camping-ground of some wanderers—the gipsies probably, concerning whom the tales and rumours were so rife and so exaggerated of late. It must have been used quite recently, for where the fire had been built the wood ash was white and undisturbed; while the crusts, bones, and fragments of a rough-and-ready meal still littered the green turf that spread in such a fresh, delicious carpet all around the spot. But now the dell was deserted. The feeling of desolation always conveyed by the sight of a burned-out fire, a forsaken hearth, struck chilly on Mr. Grey's senses, and he turned away in disappointment from the tenantless place. Then the two men gazed blankly into each other's eyes. The children could not be found; not a trace of them was to be seen, except a small battered shoe—the shoe that Joan had left behind the preceding Friday.

By this time they were so tired out that they were reluctantly obliged to give over their search for the night; so, feeling footsore, and disheartened by their want of success, they went each his own way homewards.

Mr. Grey was now thoroughly alarmed for the safety of his wife's little favourites, not knowing what mishap might have overtaken them. As for nurse, her state of mind was pitiable. She alone had been left in charge of the children, and she only was responsible to the Misses Turner for their safety. And what would Captain Dene say—her master, whom she had solemnly promised to take good care of his motherless children? She had done her best, poor Perry; for although often impatient and unsympathetic with the little ones, she loved them devotedly, and would now willingly have imperilled her own safety to secure theirs. Oh, how earnestly she wished that Miss Turner and Miss Alice were home again, or rather that they had not gone away! It was, of course, too late to communicate with them that night, but it must be done first thing next morning—as soon as the telegraph office should be open.

"How shall I face them?" cried nurse wildly, pushing cook and baby away in her impatience.

Cook looked hurt. She had good-naturedly taken care of Eric all evening, and been much diverted by his funny ways. She had offered the little fellow to nurse with the best intentions in the world, thinking that attending to his wants might distract her attention from her trouble. But nurse was not to be consoled thus. She could think of nothing except the calamity which had befallen the household in general, herself in particular, and for the time being baby was of no importance in her eyes; even the adoring Jenkins was forgotten! Nothing remained but her own nervous terror and distress.

Next morning, as soon as it was daylight, Mr. Grey hastened down to Firgrove to inquire if Perry had heard anything of the missing children. She had not, and was in a most miserable frame of mind after an anxious, sleepless night.

While she and Mr. Grey stood talking together, Tom Brook passed by on his way to work at the farm, and seeing the two in conversation, joined them. But he brought no comfort to their council with the tidings he had to tell—not much at most, yet important as furnishing a possible clue to the fate of the lost ones.

The previous forenoon some of his children at play beside the lock had noticed Master Darby and Miss Joan down along the tow-path; but as they were accustomed seeing the pair trotting about by themselves continually, here, there, and everywhere, they paid no particular attention to their movements.

"They didn't go to Copsley Wood after all, then," said Mr. Grey, looking very grave, for his fears had been directed into a fresh channel.
