I had a dog once. I thought so much of him that when he died I couldn't bear the thought of getting another in his place. He was a FRIEND—you understand, Mistress Blythe? Matey's only a pal. I'm fond of Matey—all the fonder on account of the spice of devilment that's in him—like there is in all cats. But I LOVED my dog. I always had a sneaking sympathy for Alexander Elliott about HIS dog. There isn't any devil in a good dog. That's why they're more lovable than cats, I reckon.
