Our friend then takes a higher flight, and discusses, with equal fervor and more notes of admiration, the question whether--on theological grounds--man has a right to kill these creatures, even though they be rats. But he soars into such altitudes of rhetorical theology, that we dare not follow him. He dismisses, in the same paragraph, several remedies for rats, with a brevity almost savoring of contempt; gliding gracefully from theology to arsenic and other poisons, he returns, with a gush of enthusiasm, to his old refrain, "Tiny." The breed of small terriers of the Tiny breed must be increased. "I do not mean," he says, "the little pigmy dwarf terrier; they are tantamount to useless, even where they are well-bred, not having strength enough for hunting. A dog, to be of sound service, ought to be from six to sixteen pounds weight; I would not recommend them over that, as they become too large and unwieldy for the purpose, and too expensive keeping: besides, little dogs will kill mice as well as rats, and that is a great recommendation. I would also recommend, above all others, the London rat-killing terrier; he is as hard as steel, courageous as a lion, and as handsome as a racehorse: the village dogs, on the other hand, are, generally speaking, too large, too coarse, and too soft. You ought to be as particular about breeding terriers as they are with racehorses." The writer suggests the abolition of the duty upon rat-catching terriers of the "Tiny" family; that associations should be encouraged in the rural parts of England for the promotion of rat-catching in all its branches; that the bodies of the vermin be sold for manure; and lastly, that rewards be given to the greatest killers. Literature has, from first to last, been strengthened by recruits from nearly every class; but till now we know of no volunteer who has enlisted under her banner from the ranks of rat-catching. We know not if the publication that has afforded a text for this article will effectually augment the exterminators of the rat-tribe; but this is certain, that, rat-killer though its writer be, he has produced between forty and fifty pages, in which, though there may be much comical exaggeration, there are, nevertheless, many curious facts and suggestions for abating one of the greatest animal nuisances that have infested our homes and fields, since the days when an English king levied tribute of wolves' heads upon our brethren of Wales.
