open its mouth and feel its jaw, and the pup would wriggle and squeak, and back away, opening and shutting its mouth to see if its works had been damaged. “All right!” Brownlee would say. “You wait a year or two and you'll see!” About three months later the pup was as big as an ordinary full-grown dog, and his coat looked like a compromise between a calfskin and one of these hairbrush door mats you use to wipe your feet on in muddy weather. He did not look like the same pup. He was long limbed and awkward and useless, and homely as a shopworn fifty-cent yellow plush manicure set. Murchison began to feel that he didn't really need a dog, but Brownlee was as enthusiastic as ever. He would go over to Murchison's fairly oozing dog knowledge. “I'll tell you what that dog is,” he would say. “That dog is a cross between a Great Dane and an English Deerhound. You've got a very valuable dog there, Murchison, a very valuable dog. He comes of fine stock on both sides, and it is a cross you don't often see. I never saw it, and I've seen all kinds of crossed dogs.” Then Massett would drop in and walk around the dog admiringly for a few minutes and absorb his beauties. “Murchison,” he would say, “do you know what that dog is? That dog is a pure cross between a Siberian wolfhound and a Newfoundland. You treat that dog right and you'll have a fortune in him. Why, a pure Siberian wolfhound is worth a thousand dollars, and a good—a really good Newfoundland, mind you—is worth two thousand, and you've got both in one dog. That's three thousand dollars' worth of dog!” In the next six months Fluff grew. He broadened out and lengthened and heightened, and every day or two Brownlee or Massett would discover a new strain of dog in him. They pointed out to Murchison all the marks by which he could tell the different kinds of dog that were combined in Fluff, and every time they discovered a new one they held a sort of jubilee, and bragged and swelled their chests. They seemed to spend all their time thinking up odd and strange kinds of dog that Fluff had in him. Brownlee discovered the traces of Cuban bloodhound, Kamtchatka hound, beagle, Brague de Bengale, and Thibet mastiff, but Massett first traced the stag-hound, Turkoman watchdog, Dachshund,
