they reached the Illinois, which they
followed to the point where Peoria now stands.

Here La Salle's troubles began in abundance. The Indians endeavored
to dissuade him from leading the expedition farther, and even the
explorer's own followers began to desert. Chagrinned at these untoward
circumstances and on his guard lest the Indians prove openly hostile,
La Salle proceeded to secure his position by the erection of a fort
to which he gave the name Crevecoeur. Here he left Tonty with the
majority of the party, while he himself started with five men back to
Niagara. His object was in part to get supplies for building a vessel
at Fort Crevecoeur, and in part to learn what had become of the
_Griffin_, for since that vessel had sailed homeward he had heard no
word from her crew. Proceeding across what is now southern Michigan,
La Salle emerged on the shores of the Detroit River. From this point
he pushed across the neck of land to Lake Erie, where he built a canoe
which brought him to Niagara at Eastertide, 1680. His fears for the
fate of the _Griffin_ were now confirmed: the vessel had been lost,
and with her a fortune in furs. Nothing daunted, however, La Salle
hurried on to Fort Frontenac and thence with such speed to Montreal
that he accomplished the trip from the Illinois to the Ottawa in
less than three months--a feat hitherto unsurpassed in the annals of
American exploration.

At Montreal the explorer, who once more sought the favor of Frontenac,
was provided with equipment at the King's expense. Within a few
months he was again at Fort Frontenac and ready to rejoin Tonty at
Crevecoeur. Just as he was about to depart, however, word came that
the Crevecoeur garrison had mutinied and had destroyed the post. La
Salle's one hope now was that his faithful lieutenant had held on
doggedly and had saved the vessel he had been building. But Tonty in
the meantime had made his way with a few followers to Green Bay,
so that when La Salle reached the Illinois he found everyone gone.
Undismayed by this climax to his misfortunes, La Salle nevertheless
pushed on down the Illinois, and early in December reached its
confluence with the Mississippi.

To follow the course of this great stream with the small party which
accompanied him seemed, however, too hazardous an undertaking. La
Salle, therefore, retraced his steps once more and spent the next
winter at Fort Miami on the St. Joseph to the southeast of Lake
Michigan. In the s
