Mike Sullivan, a very intelligent bar clerk at Johnsonburg, Elk County, called the writer’s attention to the length of the tail of a mounted cat in the hotel at that prosperous lumber town. “A great many wild cat hides, taken in Elk, McKean, and Forest Counties are shipped to a fur dealer in town,” said Sullivan, “and I have been struck by the length of their tails. I put a foot rule on this one, and it measured exactly twelve inches. That cat, I am told, weighed forty-one pounds. We have quite a few varieties of cats in these parts. First of all, there is the Canada Lynx, grey in color, with tabs on his ears and hair on the soles of his feet; a big, fierce fellow, often weighing fifty pounds. He has always been a scarce cat, even the Indians say he was never plentiful. Secondly, there is the true wild cat, or ‘Bob’ cat, reddish in color, mottled like a fawn, smaller than the Canadian Lynx, but with a longer tail. Thirdly, there is the tame cat gone wild—escaped from lumber camps and the like. Some of these grow very big, and in one or two generations are brindled and bushy tailed. Many people call them ‘coon cats.’ Then we have the fourth kind, the mixture, hybrid or mongrel, whatever you call it, between the Canada Lynx and the Wild Cat, or Bay Lynx. In my opinion, that cat on yonder shelf is a cross between a lynx and a Bob Cat. Old hunters tell me that the product of that cross has a longer tail than either lynx or Bob Cat—a throw back to the type of long ago. There may also be crosses between lynxes and Bob Cats and tame cats gone wild; it happened in the old country, why not here?” The above observations, which have also been advanced by C. W. Dickinson, of Smethport, have a considerable element of common-sense to them. In deer breeding there is a tendency to throw back to good-headed, or poor headed ancestors, as the case may be. In South Carolina there are frequent cases of palmation in the deer, due to some English fallow bucks liberated by planters in the Eighteenth Century. A cross between two varieties of short-tailed lynxes might provide a longer tailed type. In other respects the cat in the Johnsonburg house showed an accentuation of characters. Its hind legs were apparently twice the thickness of the front legs, and very much longer. It was an unsymmetrical animal. Perhaps much of this was due to faulty taxidermy, but that would not account for the length of the tail. Its color, a darker grey than the true lynx, was almost of a drab hue. It was darker about the head, but there were no regular spots. The Canada Lynx early succumbed to changed conditions in his faunal zone, the forest fire, the clearing, the drained swamp, the passing of the northern hare, but for a time his blood will live on in the crossbreed with the more adaptable Bay Lynx. As these long tailed cats are said to be plentiful in the wilder sections of Northwestern Pennsylvania, it may be that this new race will possess the power to best endure existing conditions—though S. N. Rhoads says that such a cross would be infertile.
