Driscol & Co. are cutting a tail-race and tunnel into good diggings. Adjoining, southeast of Fourth Crossing district, are the cement-gravel tunnel claims of Dogtown.

The Hammerschmidt & Hensel tunnel has been yielding very well; they intend to build a mill for the extraction of the gold held by the cement, which slakes hard. The Barney Hurle tunnel is going further into good ground.

The Bully Tunnel Company have struck rich pay-$200 on '75 superficial feet-but water interferes badly.

Angel's Camp and Carson Hill. - These two places have been the scene of extensive and profitable quartz-mining on the great Mother lode, and the first-named town now possesses several of the best mines found on the lode. In 1851, Carson Hill was the scene of one of the great "rushes" which then periodically occurred throughout the State. Rumor said that a mountain of quartz had been discovered, with gold enough visible for the coinage of a nation. Companies were formed, claims taken up, and hundreds of men were soon at work. Disputes as to boundaries arose, and much bloodshed followed. Most of the claims were thrown in litigation, and the rich yield of the surface was wasted in the expenses incident to protracted lawsuits. Many years elapsed before decisions were had, and in the mean time the character of the quartz changed, as the water-level was reached, and the owners, impoverished by litigation, were not able to open their mines systematically. At the present time (December, 1871) no work is being done on Carson Hill, though there are several fine mines which will be opened next year. The principal mines here are the Finnegan, or New York, the Reserve, or Stevenot, the Morgan Ground, which is said to have yielded nearly $3,000,000, the Union, and the Kentucky-all closed. Proceeding in a northwesterly direction from Carson Hill, and following the outcrop of the Mother lode, which was here very prominent, we find the following claims: Two claims at Albany Flat, name unknown, Cogswell's, Cameron's, and the Raspberry. We are now at Angel's, where we find
