THE ANCIENT LAKE AGASSIZ.

The Minnesota River, rising on the western boundary of the State,

flows nearly five hundred miles in a deeply carved valley through the

"Big Woods" to the Mississippi. Its source is in the Big Stone Lake,

which, with Lake Traverse to the northward, forms part of the Dakota

boundary. The Red River of the North, rising in Lake Traverse and

gathering together the streams on the western slope of the Itascan

plateau, flows northward between Minnesota and North Dakota, and into

Manitoba, two hundred and fifty miles to Lake Winnipeg. This river has

cut its channel in a nearly level plain, and it is curious that in

times of freshet its waters connect, through Lakes Traverse and the

Big Stone, with the Minnesota, so that steamboats of light draught can

then occasionally pass from the Mississippi waters north to Lake

Winnipeg. It was this rich and level plain of the valley of the Red

River that in the glacial epoch formed the bed of a vast lake which

scientists have named Lake Agassiz. Its area, as indicated by

well-marked shore-lines and deltas, was a hundred miles wide and over

four hundred miles long, stretching far into Manitoba, and the waters

were two to four hundred feet deep. It was held up on the north by the

retreating ice-sheet of the great glacier, the outlet being southward,

where a channel fifty feet deep, fifty miles long and over a mile

wide can now be distinctly traced leading its outflow into the

Minnesota River, whose valley its floods then greatly enlarged on the

way to the Mississippi. The plain of this lake bed is almost level,

descending towards the northward about a foot to the mile, and here

the ancient lake deposited the thick, rich, black soils which have

made the greatest wheat-growing region of North America.

The first settlement of Dakota was on the Big Sioux River at Sioux

Falls, where flour-mills and other manufacturing establishments have

gathered around a fine water-power, and there are nearly fifty

thousand people in the two towns of Sioux Falls in South Dakota and

Sioux City in Iowa. The whole region to the northward and far over the

Canadian boundary is a land of wheat-fields, with grain elevators

dotting the flat prairie at the railway stations, for all the roads

have lines to tap the lucrative trade of this prolific region. The

Northern Pacific Railway crosses Red River at Fargo, which, with the

town of Moorhead, both being wheat and flour centres, has a population

of fifteen thousand. To the westward are the vast "Bonanza" wheat

farms of Dakota, of which the best known is the Dalrymple farm,

covering forty-five thousand acres. Steam-ploughs make continuous

furrows for many miles in the cultivation, and in the spring the

seeding is done. The whole country is covered with a vast expanse of

waving, yellow grain in the summer, and the harvest comes in August.

To the westward flows James River through a similar district, and the

country beyond rises into the higher plateau stretching to the

Missouri. This fertile wheat-growing region extends far northward over

the Canadian border forming the Province of Manitoba, the name coming

from Lake Manitoba, which in the Cree Indian dialect means the "home

of Manitou, the Great Spirit." Its enormous wheat product makes the

business of the flouring-mills of Minneapolis, Duluth and many other

cities, and furnishes a vast stream of grain to go through the Soo

Canal down the lakes and St. Lawrence, much being exported to Europe.

The Canadian Pacific Railway, which provides the traffic outlet for

Manitoba, comes from the northern shore of Lake Superior at Port

Arthur northwestward up the valley of the Kaministiquia River, and its

tributary the Wabigoon, the Indian "Stream of the Lilies." This was

the ancient portage, and by this trail and Winnipeg River, the canoe

route of the Hudson Bay Company voyageurs, Lord Wolseley led the

British army in 1870 to Fort Garry (Winnipeg) that suppressed Louis

Riel's French-Indian half-breed rebellion, which had possession of the

post. The railway route is through an extensive forest, and leads near

the northern shore of the Lake of the Woods, crossing its outlet

stream at Rat Portage, so named from the numerous colonies of

muskrats, a town of sawmills standing at the rocky rim of the lake,

where its waters break through and down rapids of twenty feet fall to

seek Winnipeg River, the Ounipigon or "muddy water" of the Crees.

Here, and at Keewatin beyond, are grand water-powers, the latter

having mammoth mills that grind the Manitoba wheat and send the flour

to England. Then, emerging from the forests, the railway crosses the

rich black soils of the Red River Valley, and beyond that river enters

Winnipeg, the "Prairie City" and commercial metropolis of the Canadian

Northwest. For nearly eight hundred miles this alluvial region spreads

west and northwest of Winnipeg, with varying degrees of fertility, to

the Rocky Mountains. Here, at the junction of the Assiniboine River,

coming from the remote northwest, with Red River, has grown a Canadian

Chicago of fifty thousand people, developed almost as if by magic,

from the little settlement of two hundred and forty souls, whom

Wolseley found in 1870, around what was then regarded as the distant

Hudson Bay Company frontier post of Fort Garry. Its original name when

first established was Fort Gibraltar. The two rivers wander crookedly

over the flat land, and between them the city covers an extensive

surface. A half-dozen railways radiate in various directions, and

there are spacious car-yards and stations. Winnipeg has an energetic

population, largely Scotch and Americans, but with picturesque touches

given by the copper-colored Indians and French half-breeds, who wander

about in their native costumes, though most of these have gone away

from Red River Valley to the far Northwest. The city has good streets,

many fine buildings and attractive stores. The Manitoba Government

Buildings adjoin the Assiniboine River, and the military barracks of

Fort Osborne are alongside. Near the junction of the rivers is the

little stone gateway left standing, which is almost all that remains

of the original trading-post buildings of Fort Garry, representing the

venerable Hudson Bay Company, chartered by King Charles II. in 1670,

that controlled the whole vast empire of the Canadian Northwest. This

Company was a grant by the king originally to Prince Rupert and a few

associates of a monopoly of the fur trade over a vast territory in

North America, extending from Lake Superior to Hudson Bay and the

Pacific Ocean. In this way that portion of British America came to be

popularly known in England as "Prince Rupert's Land." The great

Company existed for nearly two hundred years, had one hundred and

fifty-two trading-posts, and employed three thousand traders, agents

and voyageurs, and many thousands of Indians. In the bartering with

the red men, the unit of account was the beaver skin, which was the

equivalent of two martens or twenty muskrats, while the pelt of a

silver fox was five times as valuable as a beaver. In 1869, when the

Dominion of Canada was formed, England bought the sovereignty of the

Company for $1,500,000 and transferred its territory to Canada. The

Company still retains its posts and stores, however, and conducts

throughout the Northwest a mercantile business. Far to the westward of

Winnipeg spread the fertile prairies of Manitoba and Assiniboia

Provinces, until they gradually blend into the rounded and

grass-covered foothills making the grazing ranges of Alberta that

finally rise into the snow-capped peaks of the Rockies.
