San Francisco Paper - Present-Day Problems in California Gold-Dredging

The first successful bucket-elevator dredge to operate in California was put in comnlisvion wt Oroville in March, 1898. There had been numerous previous attempts at dredging, but noue of the earlier boats proved a success. The gold-miners in California earl3 conceived the idea of a machine to dig gravel from the beds and bars of auriferous streams that were inaccessible by the methods then employed, and it was only a few months after the discovery of gold in California that such a machine was Shipped around Cape Horn from New York to San Francisco. Thij was, however, but the forerunner of many failures in gold-dredging, and was soon at the bottoni of the Sacramento river. During succeeding years many other unsuccessful attempts mere made, and it was not until 1897 that a dredge of the single-lift bucket-elevator type mas floated on the Yuba river. This dredge was built by the Risdon Iron Works for 12. H. Postlethwaite, and would probably have been a success if it had been operated on some of the rich Ororille ground
