Acknowledgments. — This research had its beginning in a 

 small study made for and with Professor N. S. Shaler of Harvard 

 University ; and throughout the continuance of this and of other 

 studies arising from it, he has aided it in every way, so that my 

 indebtedness to him is greater than to anyone else. 



The help derived from Mr. Faribault's map has been men- 

 tioned. Thanks are due also to Mr. B. F. Pearson and Mr. J. K. 

 Pearson, upon whose property much of the detailed work was 

 done, and who gave every facility for it ; and to owners and 

 workers of the other properties in the district.
