If Stirmingham objects to owe its origin to a water-rat, it may at least congratulate itself upon the fact that it was a good old English rat—none of your modern parvenu, grey Hanoverian rascals. It was, in fact, before the Norwegian rat, which had been imported in the holds of vessels, had obtained undisputed sway over the country. It had, however, already driven the darker aboriginal inhabitants away from the cultivated places to take refuge in the woods and streams. It is odd that in the animal kingdom also, even in the rat economy, the darker hued race should give way to the lighter. However, as in Stirmingham the smoke is so great that the ladies when they walk abroad carry parasols up to keep the blacks from falling on and disfiguring their complexion, there can after all be no disgrace in the water-rat ancestry.
This dark coloured water-rat, finding his position less and less secure at the adjacent barn on account of the attacks of the grey invaders, one fine day migrated, with Mrs. Rat and all the Master and Missy rats, down to the stream. Peeping and sniffing about for a pleasant retreat, he chose the neighbourhood of the willow tree. I cannot stay here to discuss whether or no he was led to the tree by some mystic beckoning hand—some supernatural presentiment; but to the tree he went, and Stirmingham was founded. Two or three burrows—small round holes—sufficed to house Mr. Rat and his family, but these ran right under the willow, and of course still further weakened it.
In course of time the family flourished exceedingly, and Mr. Rat became a great-great-great-grandpapa to ever so many minor Frisky Tails. These Frisky Tails finding the ancient quarter too much straightened for comfort, began to scratch further tunnels, and succeeded pretty well in opening additional honeycombs, till presently progress was stayed by a root of the tree. Now they had gnawed through and scratched away half a dozen other roots, and never paused to sniff more particularly at this than the others. But it so happened that this root was the one which supplied the green streak up the trunk of the tree with the golden sap of life drawn by mysterious chemical processes from the earth. Frisky Tails gnawed this root asunder, and cut off the supply of sap. The green streak up the trunk withered and died, and the last stay of the willow was gone. It only remained for the first savage southwester of winter to finish the mischief.
The southwester came, and over went the trunk, crash across the brook. At first this was very awkward for the rats, as thereby most of their subterranean dwellings became torn up and exposed. But very soon a geological change occurred.
The tree had fallen obliquely across the stream, and its ponderous head, or top, choked up the bed, or very nearly. The sand and small sticks, leaves, and so on, brought down by the current, filled up the crevices left by the tree, and a perfect dam was formed.
Now, as stated before, the ground thereabout was nearly level, and so worthless in character that no man ever troubled his head about it. No one came to see the dam or remove it. The result was the brook overflowed, and then finding this level plateau, instead of eating out a new channel, it spread abroad, and formed first a good-sized puddle, then a pond, then something like a flood, and, as time went by, a marsh. This marsh extended over a space of ground fully a mile long, and altogether covered some nine hundred acres.
The rats, sagacious creatures, instead of deserting their colony, showed that they possessed that species of wisdom which the Greek sage said was superior to all other knowledge—namely, the knowledge how to turn an evil to a good. Exploring this shallow lake which their carelessness had caused, they found several places still unsubmerged—islands, in fact. To one of these they swam, dug out new catacombs, and being now quite safe from interruption, and protected upon all sides, the Malthusian laws of population had full play, and soon proved its force, for the whole place swarmed with them. The axiom, however, that at the very point when empires are apparently most prosperous, their destruction is near at hand, to some extent applied even to the dominion of the water-rat. They were no longer to be the sole undisturbed possessors.
Arguing a priori, one would have concluded that if this waste land was worthless before, now it was a marsh, and miasmatic vapours arose from it, it would be still more avoided. But the facts were exactly opposite. So soon as ever the water had spread over the level plain, and had well soaked into the sterile soil, there began to spring up tough aquatic grasses, commonly called bull-polls, from a supposed resemblance between their tangled appearance and the rough hair that hangs over the poll of a bull.
These grasses are gregarious—that is to say, they prefer to grow in huge bunches. Each bunch increasing year after year, forms in time a small hillock or tuft, and, the roots spreading and spreading, these hillocks of grass almost covered the lake, leaving only narrow channels of water between. Upon these innumerable frogs and toads crawled up out of the water, and they were the chosen resorts of newts.
In summer time the blue dragonfly wheeled in mazes over them, or, while settled on the stiff blades of grass, looked like a species of blossom. The current of the brook brought down seeds, and soon the tall reed began to rear its slender stem, and rustle its feathery head in the breeze. The sedges came also, and fringed the marsh
