From Preface: "The following paper on miner's nystagmus in the United States, Mr. Hoffman has reviewed the results of investigations in Europe and has drawn some tentative conclusions as to the possible frequency of the disease in this country. Whatever may be the prevalence of nystagmus in the United States, its seriousness as a disease and the need of national and State agencies cooperating in endeavors to obtain exact information regarding it are deemed sufficient reasons for the publication of Mr. Hoffman's interesting and suggestive paper.

From Introduction: "Technical Paper 66 deals with the mud-laden fluid process in general and No. 68 with its application in Oklahoma. Rather than reprint these publications, it has been considered advisable to replace them with the present report, which includes the results of more recent investigations. The methods of using mud-laden fluid are an outgrowth of the rotary drilling system, which was developed in Texas and later employed in Louisiana and California."

From Introduction: "During the early years of these plants little success was anticipated from the use of bituminous coals and lignites, but in 1904 and 1905 it was fully demonstrated at Government testing station at St. Louis that these fuels could be utilized to excellent advantage. However, although many producer-gas plants in daily operation are still skeptical regarding the successful commercial use of these fuels."
