Then the interrupted activity of the swamp is resumed, scolding mother ducks reading the riot act to young teals, old geese coming craning and craning their long necks to drink at the water's edge, lizards and water-snakes splashing down the banks, midgets and gnats sunning themselves in clouds during the warmth of the short autumn days, with a feel in the air as of crisp ripeness, drying fruit, the harvest-home of the year. In all the prairie region north and west of Minnesota—the Indian land of "sky-coloured water"—the sloughs lie on the prairie under a crystal sky that turns pools to silver. On this almost motionless surface are mirrored as if by an etcher's needle the sky above, feathered wind clouds, flag stems, surrounding cliffs, even the flight of birds on wing. As the mountains stand for majesty, the prairies for infinity, so the marsh lands are types of repose.
But it is not a lifeless repose. Barely has the trapper settled himself when a little sharp black nose pokes up through the water at the fore end of the wriggling trail. A round rat-shaped head follows this twitching proboscis. Then a brownish earth-coloured body swims with a wriggling sidelong movement for the log, where roosts the blinking owlet. A little noiseless leap! and a dripping musk-rat with long flat tail and webbed feet scrabbles up the moss-covered tree towards the stupid bird. Another moment, and the owl would have toppled into the water with a pair of sharp teeth clutched to its throat. Then the man shies a well-aimed stone!
Splash! Flop! The owl is flapping blindly through the flags to another hiding-place, while the wriggle-wriggle of the waters tells where the marsh-rat has darted away under the tangled growth. From other idle days like these, the trapper has learned that musk-rats are not solitary but always to be found in colonies. Now if the musk-rat were as wise as the beaver to whom the Indians say he is closely akin, that alarmed marauder would carry the news of the man-intruder to the whole swamp. Perhaps if the others remembered from the prod of a spear or the flash of a gun what man's coming meant, that news would cause terrified flight of every musk-rat from the marsh. But musquash—little beaver, as the Indians call him—is not so wise, not so timid, not so easily frightened from his home as amisk,[44] the beaver. In fact, nature's provision for the musk-rat's protection seems to have emboldened the little rodent almost to the point of stupidity. His skin is of that burnt umber shade hardly to be distinguished from the earth. At one moment his sharp nose cuts the water, at the next he is completely hidden in the soft clay of the under-tangle; and while you are straining for a sight of him through the pool, he has scurried across a mud bank to his burrow.
Hunt him as they may, men and boys and ragged squaws wading through swamps knee-high, yet after a century of hunting from the Chesapeake and the Hackensack to the swamps of "sky-coloured water" on the far prairie, little musquash still yields 6,000,000 pelts a year with never a sign of diminishing. A hundred years ago, in 1788, so little was musk-rat held in esteem as a fur, the great North-West Company of Canada sent out only 17,000 or 20,000 skins a year. So rapidly did musk-rat grow in favour as a lining and imitation fur that in 1888 it was no unusual thing for 200,000 musk-rat-skins to be brought to a single Hudson's Bay Company fort. In Canada the climate compels the use of heavier furs than in the United States, so that the all-fur coat is in greater demand than the fur-lined; but in Canada, not less than 2,000,000 musk-rat furs are taken every year. In the United States the total is close on 4,000,000. In one city alone, St. Paul, 50,000 musk-rat-skins are cured every year. A single stretch of good marsh ground has yielded that number of skins year after year without a sign of the hunt telling on the prolific little musquash. Multiply 50,000 by prices varying from 7 cents to 75 cents and the value of the musk-rat-hunt becomes apparent.
What is the secret of the musk-rat's survival while the strong creatures of the chase like buffalo and timber-wolf have been almost exterminated? In the first place, settlers can't farm swamps; so the musk-rat thrives just as well in the swamps of New Jersey to-day as when the first white hunter set foot in America. Then musquash lives as heartily on owls and frogs and snakes as on water mussels and lily-pads. If one sort of food fails, the musk-rat has as omnivorous powers of digestion as the bear and changes his diet. Then he can hide as well in water as on land. And most important of all, musk-rat's family is as numerous as a cat's, five to nine rats in a litter, and two or three litters a year. These are the points that make for little musquash's continuance in spite of all that shot and trap can do.
Having discovered what the dank whiff, half animal, half vegetable, signified, the trapper sets about finding the colony. He knows there is no risk of the little still-hunter carrying alarm to the other musk-rats. If he waits, it is altogether probable that the fleeing musk-rat will come up and swim straight for the colony. On the other hand, the musk-rat may have scurried overland through the rushes. Besides, the trapper observed tracks, tiny leaf-like tracks as of little webbed feet, over the soft clay of the marsh bank. These will lead to the colony, so the trapper rises and parting the rushes not too noisily, follows the little footprint along the margin of the swamp.
Fort MacPherson, now the most northerly post of the Hudson's Bay Company, beyond tree line; hence the houses are built of imported timber, with thatch roofs.
Here the track is lost at the narrow ford of an inflowing stream, but across the creek lies a fallen poplar littered with—what? The feathers and bones of a dead owlet. Balancing himself—how much better the moccasins cling than boots!—the trapper crosses the log and takes up the trail through the rushes. But here musquash has dived off into the water for the express purpose of throwing a possible pursuer off the scent. But the tracks betrayed which way musquash was travelling; so the trapper goes on, knowing if he does not find the little haycock houses on this side, he can cross to the other.
Presently, he almost stumbles over what sent the musk-rat diving just at this place. It is the wreck of a wolverine's ravage—a little wattled dome-shaped house exposed to that arch-destroyer by the shrinking of the swamp. So shallow has the water become, that a wolverine has easily waded and leaped clear across to the roof of the musk-rat's house. A beaver-dam two feet thick cannot resist the onslaught of the wolverine's claws; how much less will this round nest of reeds and grass and mosses cemented together with soft clay? The roof has been torn from the domed house, leaving the inside bare and showing plainly the domestic economy of the musk-rat home, smooth round walls inside, a floor or gallery of sticks and grasses, where the family had lived in an air chamber above the water, rough walls below the water-line and two or three little openings that must have been safely under water before the swamp receded. Perhaps a mussel or lily bulb has been left in the deserted larder. From the oozy slime below the mid-floor to the topmost wall will not measure more than two or three feet. If the swamp had not dried here, the stupid little musk-rats that escaped the ravager's claws would probably have come back to the wrecked house, built up the torn roof, and gone on living in danger till another wolverine came. But a water doorway the musk-rat must have. That he has learned by countless assaults on his house-top, so when the marsh retreated the musk-rats abandoned their house.
