SHORE OF LAKE HURON 17 



Scarcely any attempt had yet been made to rebuild except here and 

 there a small structure. These two villages were completely swept out 

 of existence. Sawmills, piles of lumber, stores, residences, bridges, 

 and even street shade trees were consumed. No substantial business 

 had yet returned. It is a remarkable example of the sudden and com- 

 plete blotting out of villages and business by fire. 



Limitation of Species North and South Near and Along Lake 



Huron Shore 



In the following annotated list of plants the limitation of any species 

 north or south in the region visited is noted, but it seemed that several 

 plants were worthy of special mention. The last individual specimen 

 of shellbark hickory was noticed in the northern part of Arenac County, 

 last yellow barked oak near Oscoda in Iosco County, white oak near 

 Cedar Lake in Alcona County, Nyssa sylvatica near Omer in Arenac 

 County. Acer pennsylvanicum was observed first about two miles north 

 of Harris ville in Alcona County, and it was common from there north- 

 ward. The white flowering raspberry, Rubus parviflorus, was first seen 

 a few miles northwest of Rogers in Presque Isle County, and was abun- 

 dant from that point northward, while the last of the purple flowering 

 raspberry, Rubus odoratus, was noted there and not again observed 

 northward. 



Beach Plants 



Particular attention was paid to characteristic beach plants. For the 

 whole distance there was not much variation. The following appeared 

 throughout: Beach pea, Pitcher's thistle, tall wormwood, sea sand reed, 

 long-leaved reed grass, Agropyron dasystachyum, Elymus canadensis, and 

 Cakile edentula. 



The writer is much indebted to Agnes Chase, scientific assistant in 

 systematic agrostology, United States Department of Agriculture, for 

 examining the grasses; to Kenneth K. Mackenzie of New York City 

 for looking over the Carices and other difficult species; to F. F. Forbes 

 of Brookline, Massachusetts, for naming the willows; and to M. L. 

 Fernald of the Cray Herbarium at Harvard College for examining the 

 Vacciniums and other plants.
