[THE RAT.]
I.—THE RAT FAMILY AND ITS VARIETIES.
The cynical, and, as he is generally acknowledged, villainous old rat, is a near kinsman of as innocent and peaceful a community as the squirrels, rabbits, and hares are, at least the natural histories unite in telling us that they all belong to the Rodentia or gnawing animal family. The three great subdivisions of rat are the Black, Brown and Water varieties. With the latter we have nothing to do, as it is an innocent field animal that never goes near man or his works, and is not properly one of the "whiskered vermin race" or rat breed. The dock rats belong to the Brown brigade.
II.—RAT HISTORY.
Regarding the rat's history and antecedents we are informed in some books on this subject, very positively, that the common or Brown rat was brought from Norway, while other naturalists insist with a pertinacity peculiar to the tribe that the animal originally comes from Persia and India. We feel justified in believing with the majority that this kind of vermin has its origin in Asia, that venerable continent of cholera, Heathen-Chinee, and Old Testament. But again, whatsoever the different opinions may be, it is certainly found that this species of rodent is distributed over every country on the face of the earth in a very near equal way, because every ship that leaves port takes in its cargo of rats just as regularly as it does its cargo of provisions and merchandise, and thus it can be readily seen how this delicate tender blossom is carefully though unwittingly transplanted. In this way the Brown rat, which is now the strongly predominant rat party, was brought to New York and America in 1775 from England, which would doubtless give great pleasure to that part of the population with an Anglo-maniac tendency and would probably reconcile them much more to this sect of vermin. In Europe the latter made their appearance in 1730, and then spread out to every inhabitable country. "For men may come and men may go, but I go on forever" would at the first glance seem to be the case with the rat tribe as well as with the musical brooklet of Tennyson, yet the history of the rat nations is like unto the history of man—one clan waging a long and bitter war of conquest and extermination against the other until hardly any trace of the conquered but once mighty and ambitious race remains. The Black or Indigenous rat had things all its own way in North America as well as through the rest of the civilized earth, before the Brown species' sweeping invasion, the former having been entirely subdued and are now very scarce. It was easy enough for the brown rats to do this, because they were bigger, bolder, and more ferocious. Their multiplying powers, too, were sixteen times greater than the vanquished nation whose origin is shrouded in the darkest and most complete mystery.
The writer has on several occasions observed a dark colored rat on vessels coming from Brazil and other States of South and Central America that was unlike any specimen of this animal he had remembered ever seeing before. It was of a deep bluish tint, had an abnormally long tail, very large ears, and sharp, fiery, bead-like eyes, that looked in the dark like small electric lamps. Its agility and desperate nervousness was something marvelous, and its bump of destructiveness was largely developed also. This is probably a stray representative from some struggling colony of the dethroned black rat nation. Small numbers of them are occasionally brought to our own shores by these vessels. The rats generally escape from the ships, whereupon, as soon as the vessel is about to sail away again, their places are promptly filled by their brown brethren. Then the desolate black rats stray to the sewers of the city, where they are speedily overwhelmed and dispatched by members of the other faction, their inveterate foes and conquerors.
III.—THE KING'S OWN RAT CATCHER.
Although this black rat is inferior to the brown tribe in strength, size, and breeding powers, yet it must have been formidable also, for it was formerly thought necessary in England to institute the queer court position of rat catcher to the King. This was probably the case in other countries, too, but no records of it have been kept. According to an old historian this English rat catcher was a very dignified and mysterious individual, generally with gypsy blood in his veins, as it was thought necessary for him to know something of the Dark Science to properly perform his duties. He was attired in a rich manner, wearing a scarlet coat embroidered with yellow worsted on which were designed figures of rats and mice destroying wheatsheaves. He was looked at with much awe by the populace, as he turned out with a stately tread and great pomp, carrying a heavy staff with the insignia of his exalted office, whenever he took part in the royal pageants. This he did regularly, and it is also stated that he had an attendant, who never took part in the processions but who did the main part of the work, always with as much mystery as possible, upon the munificent stipend of tuppence a month, while the gentleman in the red coat superintended the job and received the glory—differing radically in this respect from the rat catchers of the present day.
IV.—RAT SOCIETY, CANNIBALISM, AND FRIENDSHIP.
Animals of nearly all kinds are fond of each other's society, and in their natural wild state are always found in herds. The city rats live in tribes or colonies of from twenty-five to sixty individuals, in the winter more and in the summer less. In the cold weather, when they are idle or at rest, they lie in one heap for the purpose of mutually heating each other. They change from the bottom to the top and alternate their positions very frequently, so as to give each one an opportunity to enjoy the warmer place at the bottom. The warmer the locality the less individuals there are in a heap. These rats live peacefully enough amongst themselves when they have enough to eat, but the minute they are apprised of a slightly vacant feeling in the region of the stomach they become the most savage of animals.
