"By jove!" he murmured, reminiscently. "It seems twenty or thirty years ago since . . . that affair. To tell the truth, I can't recollect much about the brute. Was it very ferocious?"

I remembered how it had torn at the bars of its cage in a mad endeavor to get at Gran'pa, and how it had nearly removed a handful of his beard.

"It is not seemly that we should speak ill of the departed," I said, "but Alfred was the most vindictive-looking and malicious-minded beast I've ever seen."

"It's like making brothers of our first cousins," I observed.

For a long time I thus ruminated on the past. And then I suddenly turned to the future.
