Excerpt from An Ecological Survey of Isle Royale, Lake SuperiorGentlemen - I beg to present herewith for printing, a report by Dr. Chas. C. Adams on the ecology, that is the natural history, of Isle Royale. This comes to us with the approval of Dr. A. G. Ruthven, our Chief Field Naturalist, and our Board of Scientific Advisers, and is a continuation of. The work published in our annual report for 1905.This contribution to the Biological Survey of the State, which the legislature authorized me to supervise by Act No. 250 of the session of 1905, comes from the University Museum. The explorations were made without expense to the State Survey by means of contributions from friends of the Museum. As this work is in harmony with the aims oi' the Biological Survey we are fortunate in securing such cooperation. The reports on the Porcupine Mountains and Isle Royale at the north end of the state complement the work on Walnut Lake, Oakland county, and that in Huron and Tuscola counties.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
