finished in the report for 1908. Of these, one, on the "Rise and dedine of 

 the wheat-growing industry in Wisconsin," by J. G. Thompson, has been pub- 

 Hshed during the past year. During the same period a paper on "Agriculture 

 in New England" has been presented by J. C. Marquis. The following are

 L. C. Gray. 



Dr. E. D. Jones, of Ann Arbor, who is dealing with the agricultural 

 geography of the United States and the development of the agricultural 

 market, reports progress. 



Prof. F. W. Blackmar, of the University of Kansas, has completed and 

 presented his study of "The irrigation and cultivation of arid America." 

 This is an elaborate work of 376 typewritten pages, illustrated by 171 photo- 

 graphs and 30 maps. No arrangements have been made for its publication, 

 because of certain questions which still have to be settled regarding the 

 publication policy of this Department. 



Division III.— MINING. 



Mr. Edward W. Parker states that the original plan was to subdivide the 

 work according to subjects, placing the preparation of the report on each 

 important mineral product in the hands of an expert. Three such reports 

 have been received and published privately, of which Professor Ries's 

 "History of the clay-working industry," announced as received a year ago, 

 has been published within the year by John Wiley & Sons. Four other 

 manuscripts, as mentioned in the last report, are in hand but not yet pub- 

 lished. The condition of the unfinished chapters is as follows : 



"Iron ore" is in charge of Prof. C. K. Leith, of the University of Wis- 

 consin, but as he has been absent all summer in the Hudson Bay region no 

 recent report has been received from him. 



"The history of the copper industry" is being treated by Mr. L. C. Graton, 

 formerly in charge of the subject of copper for the United States Geological 

 Survey, and now secretary of the Copper Producers' Association. This 

 work is not yet finished. 



"The history of the building-stone industry" is in charge of Dr. F. B. 

 Laney, formerly of the University of North Carolina, now with the United 

 States National Museum. Mr. Laney reports that he is making considerable 

 progress and hopes to have his manuscript completed during the coming fall. 



"The history of precious stones, abrasive materials, mica, and rare earths" 

 is being studied by Dr. Joseph Hyde Piatt, of the University of North 

 Carolina. This work is well advanced and Dr. Piatt hopes to complete the 

 chapters before the end of the present calendar year.
