in its course logs,
branches, and uprooted trees.' This was the mouth of the Missouri, 'that
savage river,' which 'descending from its mad career through a vast
unknown of barbarism, poured its turbid floods into the bosom of its
gentle sister.'

By and by they passed the mouth of the Ohio; they passed cane-brakes;
they fought mosquitoes; they floated along, day after day, through the
deep silence and loneliness of the river, drowsing in the scant shade of
makeshift awnings, and broiling with the heat; they encountered and
exchanged civilities with another party of Indians; and at last they
reached the mouth of the Arkansas (about a month out from their
starting-point), where a tribe of war-whooping savages swarmed out to
meet and murder them; but they appealed to the Virgin for help; so in
place of a fight there was a feast, and plenty of pleasant palaver and
fol-de-rol.

They had proved to their satisfaction, that the Mississippi did not
empty into the Gulf of California, or into the Atlantic. They believed
it emptied into the Gulf of Mexico. They turned back, now, and carried
their great news to Canada.

But belief is not proof. It was reserved for La Salle to furnish the
proof. He was provokingly delayed, by one misfortune after another, but
at last got his expedition under way at the end of the year 1681. In
the dead of winter he and Henri de Tonty, son of Lorenzo Tonty, who
invented the tontine, his lieutenant, started down the Illinois, with a
following of eighteen Indians brought from New England, and twenty-three
Frenchmen. They moved in procession down the surface of the frozen
river, on foot, and dragging their canoes after them on sledges.

At Peoria Lake they struck open water, and paddled thence to the
Mississippi and turned their prows southward. They plowed through the
fields of floating ice, past the mouth of the Missouri; past the mouth
of the Ohio, by-and-by; 'and, gliding by the wastes of bordering swamp,
landed on the 24th of February near the Third Chickasaw Bluffs,' where
they halted and built Fort Prudhomme.

'Again,' says Mr. Parkman, 'they embarked; and with every stage of their
adventurous progress, the mystery of this vast new world was more and
more unveiled. More and more they entered the realms of spring. The
hazy sunlight, the warm and drowsy air, the tender foliage, the opening
flowers, betokened the reviving life of nature.'

Day by day they floated down the great bends, in t
