"Feyther," said she, "ah'll sleep i' the kitchen the night. If Wully 'as ae way of gettin' oot ah'll see it, an' if he's no oot an' sheep's killed on the country-side, we'll ha' proof it's na Wully." That night Huldah stretched herself on the settee and Wully slept as usual underneath the table. As night wore on the dog became restless. He turned on his bed and once or twice got up, stretched, looked at Huldah and lay down again. About two o'clock he seemed no longer able to resist some strange impulse. He arose quietly, looked toward the low window, then at the motionless girl. Huldah lay still and breathed as though sleeping. Wully slowly came near and sniffed and breathed his doggy breath in her face. She made no move. He nudged her gently with his nose. Then, with his sharp ears forward and his head on one side he studied her calm face. Still no sign. He walked quietly to the window, mounted the table without noise, placed his nose under the sash-bar and raised the light frame until he could put one paw underneath. Then changing, he put his nose under the sash and raised it high enough to slip out, easing down the frame finally on his rump and tail with an adroitness that told of long practice. Then he disappeared into the darkness. From her couch Huldah watched in amazement. After waiting for some time to make sure that he was gone, she arose, intending to call her father at once, but on second thought she decided to await more conclusive proof. She peered into the darkness, but no sign of Wully was to be seen. She put more wood on the fire, and lay down again. For over an hour she lay wide awake listening to the kitchen clock, and starting at each trifling sound, and wondering what the dog was doing. Could it be possible that he had really killed the widow's sheep? Then the recollection of his gentleness to their own sheep came, and completed her perplexity. Another hour slowly tick-tocked. She heard a slight sound at the window that made her heart jump. The scratching sound was soon followed by the lifting of the sash, and in a short time Wully was back in the kitchen with the window closed behind him. By the flickering fire-light Huldah could see a strange, wild gleam in his eye, and his jaws and snowy breast were dashed with fresh blood. The dog ceased his slight panting as he scrutinized the girl. Then, as she did not move, he lay down, and began to lick his paws and muzzle, growling lowly once or twice as though at the remembrance of some recent occurrence. Huldah had seen enough. There could no longer be any doubt that Jo was right and more--a new thought flashed into her quick brain, she realized that the weird fox of Monsal was before her. Raising herself, she looked straight at Wully, and exclaimed: "Wully! Wully! so it's a' true--oh, Wully, ye terrible brute."
