The latest, and in some ways the most striking, instance of the peril of making a redistribution of the world’s fauna, is supplied by the beautiful tropical isle of Jamaica, home of the Demon Rum. It appears that someone in Jamaica was imperfectly enamored of the native rats, which are creatures of eminent predacity, intrepid to a degree that is most disquieting. This person introduced from a foreign land the mongoose—an animal whose name it seems prudent to give in the singular number. The mongoose, as is well known, is affected with an objection to rats compared with which the natural animosity of a dog to another dog is a mild passion indeed, and that of a collector of customs to holy water seems hardly more than a slight coolness. Jamaica is now ratless, but, alas, surpassingly tickful. The ticks have so multiplied upon the face of the earth that man and beast are in equal danger of extinction. The people hardly dare venture out-of-doors to plant the rum vine and help the north-bound steamers to take on monkeys. The mongoose alone is immune to ticks.

It appears that when this creature had effaced the rats it was itself threatened with effacement from lack of comestible suited to its tooth; but instead of wasting its life in repinings and unavailing regrets—instead of yielding to the insidious importunities of nostalgia, it fell upon the lizards and banqueted royally if roughly; and soon the lizards had gone to join the rats in the Unknown. Now, the Jamaica lizard had for countless ages “wittled free” upon ticks, maintaining among them a high death-rate with which, apparently, their own dietetic excesses (for ticks are greatly addicted to the pleasures of the table) had nothing to do. The lizard abating his ravages, through being himself abated by the mongoose, the tick holds dominion by the unchallenged authority of numbers. Man, the whilom tyrant, flees to his mountain fastnesses, the rum vine withers in the fields and the north-bound steamer sails monkeyless away. Jamaica’s last state is worse than her first and almost as bad as ours. She is as yet, however, spared the last and lowest humiliation that a brave and generous people can experience; her parasites do not pose as patriots, nor tickle the vanity of those whom they bleed.
