After following the dusty road through a flat brown plain, in about a mile and a half they passed what Mr. Grigsby said was the famous Sutter's Fort. With its thick clay walls and square towers at the corners, pierced with loopholes, it did indeed look like a fort. Inside the walls were several clay buildings where the captain had lived and stored his goods and taught his Indians to do white man's work. He had erected his fort here in 1839, and had been given all the land about, by the Mexican government of California. But now the fort was deserted; the doors and windows had been broken in, most of the wood had been torn out and carried off, and the fields about had been used as pasturage by the gold seekers. No wonder that the captain felt aggrieved; and it was pretty hard on him, when really because of his saw-mill had gold been discovered. This was poor reward for having settled the country and built a saw-mill--and a flour mill besides. "There's the Rio Americano," spoke Mr. Grigsby, pointing ahead, after they had passed old Fort Sutter. About a quarter of a mile before on the left, a line of trees indicated the course of a river--the American. And a fine stream it proved to be, flowing clear and sparkling between wooded grassy banks. The road, still dusty, turned slightly, and ascended along the river, making toward the rolling brown foothills which shimmered in the blue distance, with the mighty snow-crests of the Sierra Nevada range glinting beyond them. In the shallows and on the bars of the American parties of miners were at work digging away with spades and picks, and squatting to wash out the gold in their pans. They all were so busy that they seemed to note nothing on either side of them or overhead. Their eyes were glued to the sand and the holes and the pans. Other parties had halted by the way, for rest in the shade of trees; and these hailed the Adams party with the usual calls: "How far to the diggin's, strangers?" "This is the American, ain't it?" "Say! How much do you s'pose a man can dig in a day, up there?" "Where you folks from, and where you bound?" "Is it always this hot in Californy?" And so forth, and so forth. Several parties on their way back to Sacramento also were met; they were brown and hairy and rough and ragged, and some of them limped weakly as if they could scarcely carry their weapons, picks, spades, crowbars and blanket-rolls. They all were received with a perfect volley of excited queries from the resting parties--to which they replied with wave of hand and sometimes with a triumphant flourish of a fat little sack. But Mr. Grigsby paused not for the gold seekers in the river, or under the trees, or on the way down. He tramped stoutly, with his long stride; Charley just as stoutly followed behind, leading the packed burro, and at the tail of the burro strode, a little unevenly, the tall and soldierly Mr. Adams.
