Mr. Edward W. Parker, in submitting his report of progress on the history 

 of mining industry, states that during the year actual progress has been made 

 by the different experts to whom the preparation of the histories of the dif- 

 ferent subjects had been committed. At the time of making the last annual 

 report manuscripts had been completed as follows : 



Cement, g>'psum, and magnetite, by Mr. Edwin C. Eckel, of the U. S. Geological Survey. 

 Petroleum and natural gas, by Prof. George P. Grimsley, of the Geological Survey of 



West Virginia. 

 Bituminous coal, by Prof. W. S. Landis, of Lehigh University. 

 Anthracite coal, by \lx. Henry H. Stock, of Scranton, Pennsylvania. 



Recently Mr. Walter R. Ingalls has completed his histories on lead and 

 zinc, and these have been published as a separate volume. Prior to this Mr. 

 Ingalls had published, in the Transactions of the American Institute of Min- 

 ing Engineers, a chronology of lead mining (vol. xxxviii, 1907). 



A history of gold and silver, by Prof. Walter R. Crane, of the Columbia 

 University School of Mines, New York, has been completed and published as 

 a separate volume. This private and advance publication of Professor Crane 

 contains some material which it will be necessary to eliminate for the Car- 

 negie Institution publications, but other portions of it will appear in such pub- 

 lications in a condensed form. 



The history of the clay-working industry, by Prof. Heinrich Ries, of Cor- 

 nell University, has been received, but is not yet published. 



The history of the copper-mining industry was originally confided to Dr. 

 M. M. Bolles, of Columbia University. Dr. Bolles was obliged to withdraw 

 from this work, and it was then confided to Mr. L. C. Graton, of the U. S. 

 Geological Survey. Mr. Graton has already collected and assembled much 

 material for the complete manuscript. The material already collected relates 

 principally to the history of production and producing sources and to the de- 

 velopment of methods of production. Mr. Graton has procured some impor- 

 tant original data concerning attempts to form copper monopolies, such as the 

 Scranton "corner" ; also a considerable amount of new information about 

 prices and uses. 



Prof. Charles E. Munroe, of the George Washington University, having 

 charge of the work on chemical mineral industries, will be able to present his 

 complete manuscript by the end of the present calendar year.
