“You see, there’s getting to be a shorter crop of the best skins every year to meet a growing demand,” he proceeded, after the manner of one who had the points at his fingers’ ends from constant study. “That means commoner pelts have to take the place of those that are falling off. Many of these are muskrat and skunk skins, and even the common house tabby is called on to help tide over the shortage. What with a skillful use of dyes, and even the sewing of white hairs in black skins, they manage to deceive the public.”

He showed them how he could feed some of his queer pets. Tubby at a distance was holding his hands together, and looking very much distressed when he saw a dozen of the striped animals all around Ralph, and acting like chickens on the farm when grain was being thrown to them.

Later on, when the boys were thinking of turning away and continuing their investigations further, they heard a great outcry from near at hand.

“Hey! Ralph, everybody come quick, and chase this skunk away! He’s bent on making up to me, and I can see from the way he looks that he just knows I’m a hater of his species. Oh! please hurry and save me!”

Laughing at the frantic appeal in Tubby’s voice, they hastened toward him, to find that the fat boy in desperation had actually climbed a tree, while a very small specimen of the inmates of the corral was moving about below, now and then looking upward, as if wondering why he was not given something to eat, as usual.

They rescued Tubby by Ralph coaxing the “terrible beast” to move away. Tubby looked red in the face, and also seemed to be a little ashamed at having shown the white feather.

“Well, I admit it was a bad case of rattles with me,” he said, with a grimace; “but, then, there’s a reason. I’ve been there before, and I know that the smaller they are the more likely you may be to get them angry. But all’s well that ends well. I’m glad you’re done with this particular pen. Now show us your mink and otter, won’t you, Ralph?”

“I can show you where I keep them, and what I’ve done to induce them to feel at home and multiply,” replied the other, “but I doubt whether we catch sight of a single member of the community. They are that shy they seldom come out in the daytime. As to feeding them, all we have to do is to see that there are plenty of fish in the brook that runs through the lot.”

“But if that brook comes and goes, what’s to prevent your high-priced mink and otter from following it out?” inquired Andy, who never liked to puzzle over anything unnecessarily when the answer could be obtained simply by asking.

“Oh! we’ve fixed that by a regular barred gate at either end,” explained Ralph. “The water can escape, ditto very small fish; but we keep larger ones stocked in the stream; and those fur-coated fishers can always get a mess.”
