"What camp's this?" he hailed, as they passed a party of miners delving and washing in a little ravine.

"This is the Shirt-tail Diggin's, stranger, where everybody's happy and the goose hangs high."

Shirt-tail Diggin's consisted of a collection of tents and of lean-to shacks made of boughs and canvas, three or four log cabins, and a store, scattered along the side of the valley, amidst great trees. To the east showed the bluish gap, of which Mr. Grigsby had spoken, in the hills, and beyond the hills was the snowy range. Through the valley coursed the river—the North Branch of the American, according to Mr. Grigsby; and in the river shallows and along the banks and in ravines and ditches on both sides, up the slopes themselves, with pick and spade and pan and cradle were working the miners.

As with his father and Mr. Grigsby and the burro he drew near, Charley was surprised to hear a cheer—and another, and another, as if in greeting. Why was that? Was it a joke? But see! Arms were pointing, hats were waving, and shout joined with shout:

"Emigrants in sight! Here they come—the overlanders! Tumble out, boys!"

ANOTHER GREAT DISCOVERY

Sure enough! Following a trail out from among the timbered slopes to the east, there emerged from the gap a white-topped wagon—and another, and a succession of dots of other vehicles and of people horseback, until a long line was winding down through the green and brown. Yes, emigrants! Charley had seen such wagons, and even such a procession, before, in Missouri; but this was different, because these wagons and people had come clear across the 2,000 miles of plain and mountain and desert, from the Missouri River! Think of that!

From their ditches and ravines out clambered the miners all, to wipe their brows and gaze and cheer. And on weaved the line, until the people afoot, also—even women, and some children—could be seen trudging beside the wagons.
