"Who made it?" demanded Lige, who resented any one having been ahead of them in pioneer life.

"The trail was first made in 1813 by what was known as the Astorian Expedition, which set out from St. Louis with about a hundred men, intending to cross the mountains and build a fort for the American Fur Trading Company in Oregon. You boys should read the history of that expedition; you would find it most interesting."

"Did they get there?" asked Sam, who was always interested in the result of any adventure.

His father smiled. "Yes, Sam, they got there. When I knew that a part of our journey would lead us along the old Oregon Trail I read up its history. They had a terrible journey, but after great losses and hardships seven men reached the Columbia River, where they built a fort which they called Astoria, after John Jacob Astor of New York, the president of the fur company. The Indians set upon them and stole their goods and their stock, and they returned to St. Louis with only one old horse, which they had succeeded in trading for with a friendly Indian."

"But that was so long ago, Father," put in Joe, "I should think the trail would have been lost since."

"It probably would have been," answered his father, "but that it was kept open by the Oregon emigration of 1832. But it was beaten into its present good condition and has been kept so by the gold-seekers and emigrant trains that began the rush to California in 1849. This is also sometimes called the 'Mormon Trail,' because it was over this very road that we are traveling now that the Mormons passed on their pilgrimage to Salt Lake in 1847. They, too, had great hardships and losses, and had to winter at Florence, a little trading-station on the Missouri River, which we should reach very soon now."

"Jiminy, that's interesting," cried Joe, who had been listening intently; "it makes it so much more interesting when you think of who's been over this old road before. How much easier and pleasanter it is to learn history and geography when you're right on the spot than when you are sitting on a hard bench at school!"

Toward evening the country became more rolling, and shortly before sunset they saw in the distance a blue haze and high steep bluffs.

Joe, whose eyes were always on the alert, cried, "River ahead!"

Mr. Peniman, who was studying a map spread out on his knees, looked up.
