PRELIMINARY LIST OF TAMARACK BOGS IN OHIO. 
A. D, SELBY. 
The tamarack bogs, or as some have called them, the 
Canadian bogs of Ohio are, according to present knowledge, 
limited to possibly twelve counties of northeastern Ohio 
and possibly four counties of extreme northwestern Ohio. 
The northeast counties include Ashtabula, Trumbull, 
Geauga, Portage, Wayne, Summit, Stark and Columbiana 
counties in which the locations of a portion of the swamps 
are recorded; for Lake, Cuyahoga and Medina counties 
where such bogs are likely to exist, no records are at hand. 
For extreme northwestern Ohio three or four bogs 
are on record in Williams and Defiance counties, while Ful- 
ton, Henry and perhaps two more adjacent counties may 
supply records to extend the list. I am fully aware that the 
present list can scarcely include half the known tamarack 
bogs of the counties in which such are listed. This imper- 
fect knowledge is in part attributable to my disappointment 
in making the investigation of the plants of the tamarack 
bogs of Ohio for which the trustees of the Academy made 
a grant last spring. The first young man who proposed 
to assist, later went on a trip to Europe while the second 
was called to a position outside the state before he had fairly 
begun. The season however was rather unfavorable for 
bog work owing to the high water levels, and quite likely 
even better work may be accomplished another season — at 
least it is so hoped at present.
