It was obvious that the sand bar where he was placering had once been the river bed, but when the mighty stream, in the course of centuries, cut into the mountain opposite it changed the channel, leaving bed rock and bowlders, which eventually were covered by sand and gravel deposited by the spring floods. In this deposit there was enough flour-gold to enable any good placer miner to make days' wages by rocking the rich streaks along the bars and banks.
This particular sand bar rose from a depth of five feet near the water's edge to a height of two hundred feet or more against the mountain at the back. There was enough of it carrying fine gold to inflame the imagination of the most conservative and set the least speculative to calculating. A dozen times a day Bruce looked at it and said to himself: "If only there was some way of getting water on it!"
For many miles on that side of the river there was no mountain stream to flume, no possibility of bringing it, even from a long distance, through a ditch, so the slow and laborious process he was employing seemed the only method of recovering the gold that was but an infinitesimal proportion of what he believed the big bar contained.
While he worked, the sun came up warm, and then grew dim with a kind of haze.
"A storm's brewing," he told himself. "The first big snow is long overdue, so we'll get it right when it comes."
His friends, the kingfishers, who had lived all summer in a hole at the top of the bank, had long since gone, and the camp-robbers, who scolded him incessantly, sat silent in the tall pine trees near the cabin. He noticed that the eagle that nested in an inaccessible peak across the river swooped for home and stayed there. The redsides and the bull trout in the river would no longer bite, and he remembered now that the coyote who denned among the rocks well up the mountain had howled last night as if possessed: all signs of storm and winter.
By noon a penetrating chill had crept into the air, and Bruce looked oftener across the river.
"It's just like him to stay out and sleep under a rock all night with a storm coming," he told himself uneasily.
This would be no new thing for Slim in one of his ugly moods, and ordinarily it did not matter, for he kept his pockets well filled with strips of jerked elk and venison, while in the rags of his heavy flannel shirt he seemed as impervious to cold as he was to heat.
