"Why, Tod, what are you doing?" called Mr. Hobbs through the open window; "you will surely be bitten."

Instead of replying or heeding the words, the lad turned his pale face toward his friend and shook his head, as a warning for him to make no noise. Then he resumed his advance to the open outer door, doing so with great care and stealth, as if afraid of being heard by the brute.

The entrance to the old Woodvale school building was reached by two steps, consisting of the same number of broad high stones worn smooth by the feet of the hundreds of children that had trod them times without number. To make his way into the entry where the pupils hung their hats and bonnets on the double rows of pegs, Tod had to move slowly and carefully use his crutches. Being tipped with iron he could not set them down on the smooth stones without causing noise.

But he acted without hesitation. The teacher read his purpose and knew it was useless to try to check him. He leaned his head out of the window and held his breath, while he watched him.

Tod never faltered, though none could have understood the danger he ran better than he. He had a brother and sister among the children that had scattered in such haste before the snapping cur, and who were gathering again around the building despite the warning gesture of the teacher.

He could not know whether they had all escaped or not, but he was sure that if the dog came forth again, more than one of them must suffer, and in those days there was no Pasteur with his wonderful cure to whom the afflicted ones could be taken.

Tod did not tremble, though it seemed to him the brute must hear the tumultuous throbbing of his heart and rush forth. Puny as was his strength, he meant that, if he did so, he would steady himself on his one support, and grasping the other with both hands, strike the dog with might and main. It is doubtful whether the blow would have stunned the dog, for the little fellow's confidence in himself was greater than his bodily powers warranted.

At the moment he rested the end of the crutch on the smooth surface of the second stone, it slipped, and only by a strong wrench did he save himself from falling. The noise was heard by the animal, who was not six feet distant, and he emitted another moan, which can never be forgotten by those that have heard it.

Certain that the cur was about to rush forth, Tod steadied himself on the single crutch, and, reversing the other, held it firmly in his weak hands. He knew the shuffling sound was caused by the animal moving: uneasily about the entry, and it was strange he did not burst through the open door. But he did not do so, and, like a flash, the cripple shifted his weapon in place under his shoulder. Then, with the same coolness he had shown from the first, he reached his hand forward and grasped the latch.

The smart pull he gave, however, did not stir it. It resisted the effort, as though it was fastened in position. If such were the fact, his scheme was futile.
