THE GEOLOGY OP MINNESOTA. 



LETTER OF N. H. WINCHELL, STATE GEOLOGIST. 



UNIVERSITY OF MINNESOTA, 

 MINNEAPOLIS, September 1, 1899. 







Hon. John S. Pillsbury, President of the Board of Regents: 



MY DEAR SIR: The last volume of the final report of the Geological and Natural 

 History Survey of the state, which is herewith tendered for publication, contains 

 the results of long-continued investigation of the mineralogy and petrology of the 

 state. A large portion of this volume was already prepared when volume iv was 

 presented, indeed, the conclusions given in that volume were based on the investi- 

 gations which are given in more detail in this. It is hoped that this volume will 

 add something to the science of the crystalline rocks. 



Respectfully submitted, 



N. H. WINCHELL, 



State Geologist.
