A quarter of a mile higher up a ledge of rock ran across the valley, and over it in the old time the Yuba had poured in a cascade seventy feet deep into the ravine. But the rock now was level with the gravel, only showing its jagged points here and there above it. This ledge had been invaluable to the diggers: without it they could only have sunk their shafts with the greatest difficulty, for the gravel would have been full of water, and even with the greatest pains in puddling and timber work the pumps would scarcely have sufficed to keep it down as it rose in the bottom of the shafts. But the miners had made common cause together, and giving each so many ounces of gold or so many days' work had erected a dam thirty feet high along the ledge of rock, and had cut a channel for the Yuba along the lower slopes of the valley. Of course, when the rain set in, as everybody knew, the dam would go, and the river diggings must be abandoned till the water subsided and a fresh dam was made; but there were two months before them yet, and everyone hoped to be down to the bedrock before the water interrupted their work. The hillside, both in the Yuba Valley and for some distance along Pine Tree Gulch, was dotted by shanties and tents; the former constructed for the most part of logs roughly squared, the walls being some three feet in height, on which the sharp sloping roof was placed, thatched in the first place with boughs, and made all snug, perhaps, with an old sail stretched over all. The camp was quiet enough during the day. The few women were away with their washing at the pools, a quarter of a mile up the Gulch, and the only persons to be seen about were the men told off for cooking for their respective parties. But in the evening the camp was lively. Groups of men in red shirts and corded trousers tied at the knee, in high boots, sat round blazing fires, and talked of their prospects or discussed the news of the luck at other camps. The sound of music came from two or three plank erections which rose conspicuously above the huts of the diggers, and were bright externally with the glories of white and colored paints. To and from these men were always sauntering, and it needed not the clink of glasses and the sound of music to tell that they were the bars of the camp. Here, standing at the counter, or seated at numerous small tables, men were drinking villainous liquor, smoking and talking, and paying but scant attention to the strains of the fiddle or the accordion, save when some well known air was played, when all would join in a boisterous chorus. Some were always passing in or out of a door which led into a room behind. Here there was comparative quiet, for men were gambling, and gambling high. Going backwards and forwards with liquors into the gambling room of the Imperial Saloon, which stood just where Pine Tree Gulch opened into Yuba Valley, was a lad, whose appearance had earned for him the name of White Faced Dick.
