Book excerpt: Excerpt from Hydraulic-Mining Debris in the Sierra Nevada The principal field work of this investigation was performed in the years 1905 to 1908. The primary motive of the study was economic, and for this reason especially a prompt report of the results should have been submitted, but the actual long delay was caused by illness. After some progress had been made in the preparation of this paper, I found great need for the results of a laboratory study which had been undertaken as ancillary to the field work, and the manuscript was laid aside until the laboratory data could be discussed.' Dur ing the period of delay some supplementary field work has been done - ln the summer of 1909 by Mr. W. D. Johnson, in 1910 by Mr. W. C. Mendenhall, in 1913 by Mr. A. M. Gilbert, and in 1913 and 1914 by me. In 1907 I was assisted in field work by Mr. George Manship and in 1908 by Mr. H. S. Pond. Mr. S. K. Baker, Mr. C. L. Nelson, Mr. E. C.
