4 BIBLIOGRAPHY OF TENNESSEE GEOLOGY. 



who has gone through all of the geological library of Vanderbilt University, 

 including Professor Safford's books, so that including a large number of 

 titles from the reports of the Chief of Engineers, State Board of Health, 

 and similar publications, he added nearly a thousand titles to those pre- 

 viously obtained. Mr. Nelson has aided in preparing the index and in the 

 proof reading. 



The government reports are usually to be obtained by request from the 

 heads of the several bureaus, thus letters for such reports should be ad- 

 dressed to: The Director, U. S. Geological Survey, Washington, D. C.; The 

 Superintendent of the Coast and Geodetic Survey, Washington, D. C.; The 

 Director, Office of Public Roads, Agricultural Department, Washington, D. 

 C.; Chief of Bureau of Soils, Department of Agriculture, Washington, D. C.; 

 Chief Forester, Forest Service, Washington, D. C., etc. A few of the pub- 

 lications are sale publications, such as the topographic atlas sheets and the 

 folios of the U. S. Geological Survey. In these cases, the charges made are 

 simply to cover the cost of printing and binding. The topographic atlas 

 sheets can be obtained at a cost of five cents each, and the folios for twenty- 

 five cents each (stamps not accepted). In some cases the supply of these 

 publications for distribution for the several bureaus will be found to have 

 been exhausted. Application shcmld then be made to the Superintendent 

 of Documents, Washington, D. C., from whom they may be purchased at 

 the cost of publication. If the supply of that official is exhausted, they can 

 only be obtained from second hand book dealers, or from people to whom 

 they were previously sent. Many of these publications can be consulted at 

 the libraries, as most of the libraries receive full sets of the government 

 publications.
