LETTER OF TRANSMITTAL 



OFFICE OF THE STATE GEOLOGIST, 

 LANSING, MICH., Oct. 30, 1905. 



To the Honorable, the Board of Geological Survey of the State of Mich- 

 igan: 



Hon. Fred M. Warner, President. 



Hon. L. L. Wright. 



Hon. Patrick H. Kelley, Secretary. 



Gentlemen: I herewith transmit for publication, in the Annual Report 

 of the Board for 1905, the following report. This is a contribution to the 

 Biological Survey of the State, which the Legislature authorized you to 

 supervise and execute by Act No. 250 of the Session of 1905. The follow- 

 ing report is the result of a natural history survey made in the Porcupine 

 Mountains and on Isle Royale by a party from the University Museum, 

 University of Michigan. It is not a mere list of plants and animals, but a 

 study of these forms in relation to their surroundings. It is thus a con- 

 tribution to the natural history of the Upper Peninsula, and in addition 

 to its scientific value will, I trust, be of use to teachers in all parts of this 

 region and stimulate them in the study of the forms of life about them. 



Very respectfully, 



ALFRED C. LANE.
