The spirit of perversity entered into Ted, and merely because he was told not to tease Don he went on doing it, pretending that it was for the dog's good. Don took no heed of his pats, commands, reproaches, or insults, till Ted's patience gave out; and seeing a convenient switch near by he could not resist the temptation to conquer the great hound by force, since gentleness failed to win obedience. He had the wisdom to chain Don up first; for a blow from any hand but his master's made him savage, and Ted had more than once tried the experiment, as the dog remembered. This indignity roused Don and he sat up with a growl. Rob heard it, and seeing Ted raise the switch, ran to interfere, exclaiming: 'Don't touch him! Dan forbade it! Leave the poor thing in peace; I won't allow it.' Rob seldom commanded, but when he did Master Ted had to give in. His temper was up, and Rob's masterful tone made it impossible to resist one cut at the rebellious dog before he submitted. Only a single blow, but it was a costly one; for as it fell, the dog sprang at Ted with a snarl, and Rob, rushing between the two, felt the sharp teeth pierce his leg. A word made Don let go and drop remorsefully at Rob's feet, for he loved him and was evidently sorry to have hurt his friend by mistake. With a forgiving pat Rob left him, to limp to the barn followed by Ted, whose wrath was changed to shame and sorrow when he saw the red drops on Rob's sock and the little wounds in his leg. 'I'm awfully sorry. Why did you get in the way? Here, wash it up, and I'll get a rag to tie on it,' he said quickly filling a sponge with water and pulling out a very demoralized handkerchief. Rob usually made light of his own mishaps and was over ready to forgive if others were to blame; but now he sat quite still, looking at the purple marks with such a strange expression on his white face that Ted was troubled, though he added with a laugh: 'Why, you're not afraid of a little dig like that, are you, Bobby?' 'I am afraid of hydrophobia. But if Don is mad I'd rather be the one to have it,' answered Rob, with a smile and a shiver. At that dreadful word Ted turned whiter than his brother, and, dropping sponge and handkerchief, stared at him with a frightened face, whispering in a tone of despair: 'Oh, Rob, don't say it! What shall we do, what shall we do?' 'Call Nan; she will know. Don't scare Aunty, or tell a soul but Nan; she's on the back piazza; get her out here as quick as you can. I'll wash it till she comes. Maybe it's nothing; don't look so staggered, Ted. I only thought it might be, as Don is queer.' Rob tried to speak bravely; but Ted's long legs felt strangely weak as he hurried away, and it was lucky he met no one, for his face would have betrayed him. Nan was swinging luxuriously in a hammock, amusing herself with a lively treatise on croup, when an agitated boy suddenly clutched her, whispering, as he nearly pulled her overboard:
