Parties were sent up both branches to reconnoitre. Lewis and Clark ascended the high ground in the fork and looked toward the sunset. Innumerable herds of buffalo, elk, and antelope were browsing as far as the eye could reach, until the rivers were lost in the plain.
Back came the canoes undecided. Then the Captains set out. Clark took the crystal pebbly southern route. Lewis went up the turbid northern branch fifty-nine miles.
"This leads too far north, almost to the Saskatchewan," he concluded, and turned back. In the summer sunshine robins sang, turtle doves, linnets, the brown thrush, the goldfinch, and the wren, filled the air with melody.
"I will call it Maria's River, for my beautiful and amiable cousin, Maria Wood of Charlottesville," thought Lewis, with a memory of other Junes in old Virginia.
When Lewis drew up at camp, Clark was already there, anxious for his safety. The main party, occupied in dressing skins and resting their lame and swollen feet, looked eagerly for the decision. To their surprise both Captains agreed on the southern route.
"But Cruzatte," exclaimed the men, "he thinks the north stream is the true river, and Cruzatte is an experienced waterman. We may be lost in the mountains far from the Columbia."
"True. Everything depends on a right decision. Captain Clark, if you will stay here and direct the deposit of whatever we can spare, I will go ahead until I know absolutely."
At dawn Lewis set out with Drouillard, Gibson, Goodrich, and Joe Fields.
Under Captain Clark's direction, Bratton, the blacksmith, set up his forge at the mouth of Maria's River and Shields mended all the broken guns. The rest dug a cache, a kettle-shaped cellar, on a dry spot safe from water. The floor was covered with dry sticks and a robe. Then in went the blacksmith's heavy tools, canisters of powder, bags of flour and baggage,—whatever could be spared. On top was thrown another robe, and then the earth packed in tight and the sod refitted so that no eye could detect the spot.
The red pirogue was drawn up into the middle of a small island at the mouth of Maria's River and secured in a copse.
