He reached his decision to remain over night at The Place while he and the Mistress and the Master were sitting on the vine-hung west veranda after dinner, watching the flood of sunset change the lake to molten gold and the sky to pink fire. It would be pleasant to steal another few hours at this back-country House of Peace before returning to the humdrum duties of camp. And the guest yielded to the temptation. "I'm mighty glad you can stay over till morning," said the Master. "I'll send word to Roberts not to bring up the car." As he spoke, he scrawled a penciled line on an envelope-back; then he whistled. From a cool lounging-place beneath the wistaria-vines arose a huge collie--stately of form, dark brown and white of coat, deep-set of eye and with a head that somehow reminded one of a Landseer engraving. The collie trotted up the steps of the veranda and stood expectant before the Master. The latter had been folding the envelope lengthwise. Now he slipped it through the ring in the dog's collar. "Give it to Roberts," he said. The big collie turned and set off at a hand-gallop. "Good!" approved the guest. "Bruce didn't seem to be in any doubt as to what you wanted him to do. He knows where Roberts is likely to be?" "No," said the Master. "But he can track him and find him, if Roberts is anywhere within a mile or so from here. That was one of the first things we taught him--to carry messages. All we do is to slip the paper into his collar-ring and tell him the name of the person to take it to. Naturally, he knows us all by name. So it is easy enough for him to do it. We look on the trick as tremendously clever. But that's because we love Bruce. Almost any dog can be taught to do it, I suppose. We--" "You're mistaken!" corrected the guest. "Almost any dog CAN'T be taught to. Some dogs can, of course; but they are the exception. I ought to know, for I've been where dog-couriers are a decidedly important feature of trench-warfare. I stopped at one of the dog-training schools in England, too, on my way back from Picardy, and watched the teaching of the dogs that are sent to France and Flanders. Not one in ten can be trained to carry messages; and not one in thirty can be counted on to do it reliably. You ought to be proud of Bruce." "We are," replied the Mistress. "He is one of the family. We think everything of him. He was such a stupid and awkward puppy, too! Then, in just a few months, he shaped up, as he is now. And his brain woke." Bruce interrupted the talk by reappearing on the veranda. The folded envelope was still in the ring on his collar. The guest glanced furtively at the Master, expecting some sign of chagrin at the collie's failure. Instead, the Master took the envelope, unfolded it and glanced at a word or two that had been written beneath his own scrawl; then he made another penciled addition to the envelope's writing, stuck the twisted paper back into the ring and said-- "Roberts."
