Five days ago, just after Old Joe's last visit, Pine Heglin's cherished mongrel had gone strolling past a limpid pond on Pine's farm. He'd looked into the water, seen his own reflection, decided that he was being challenged by a big and rather ugly dog, and promptly jumped in to give battle. The reflection disappeared as soon as he was in the water, but reflections were too complex for one of his mental capacity. All he knew was that he had seen another dog. He was sure that it must be lurking in the pond, and though he never got many ideas, he stuck by those he did get. Presently, still looking determinedly for the other dog, he sank and did not come up.

Though Pine could have borrowed any hound that any of his neighbors owned, he remained loyal to his conviction that mongrels are superior. He dickered with Sad Hawkins, an itinerant peddler who'd sell or swap anything at any time, and in exchange for six chickens and a shoat Pine got another mongrel.

It was a smaller dog than his former prize, but so tightly packed and heavily muscled that it weighed nearly as much. With a generous portion of pit bull among his assorted ancestors, the dog feared nothing. He differed from Pine's former mongrel insofar as he had some sense.

Knowing as well as Old Joe where his guinea hens roosted, and aware of the fact that they were being raided, Pine left this dog in the grove with them. Thus came Old Joe's second shock of the night.

The dog, who wouldn't waste time barking or growling if he could fight, achieved complete surprise and attacked before Old Joe even knew he was about. Since he couldn't run, he had to fight.

The weight was nearly even, with the dog having perhaps a five-pound advantage. In addition, before he came into the possession of Sad Hawkins, he'd made the rounds of behind-the-barn dog-fights and he had never lost one. He could win over most coons.

The dog was a slugger. But Old Joe was a scientific boxer who knew better than to stand toe-to-toe and trade punches. He yielded to the dog's rushes even while he inflicted as much punishment of his own as possible. However, the battle might have been in doubt had it not been for one unforseen circumstance.

Hard-pressed by a determined and fearless enemy, Old Joe reached deep into his bag of tricks. He knew the terrain, and some fifteen feet away was a steep little knoll. It was elemental battle tactics that whatever might be in possession of any height had an advantage over whatever might attack it. At the first breathing spell, Old Joe scurried to the knoll, climbed it, and waited.

He was more than mildly astonished when the dog did not rush immediately. But the dog hadn't had a keen sense of smell to begin with. The numerous fights in which he'd engaged wherein his hold on a vanquished enemy was broken with a liberal application of ammonia, had ruined the little he did have. The dog was now unable to smell a dish of limburger cheese on the upwind side if it was more than three feet away, and he could not renew the battle simply because he couldn't find his enemy.
