OHIO STATE ACADEMY OF SCIENCE. Tie 
While it is well known that there are many swamps. 
and bogs in Lorain, Erie, Logan, Champlain and Clark 
counties, as well as many others, so far as I have been able 
to learn none of these contain tamarack as an original floral 
constituent. We have characteristic trees, notably the 
Arbor Vite in some of these swamps, conspicuously so in 
the Cedar swamps reached from Bowlusville near the boun- 
dary of Champlain and Clark counties. I was assured 
that swamps exist in southern Logan county of the same 
“Cedar’’ character, but it was lacking in several that I visited. 
How may we account for the absence of these bogs 
or this -particular tree in the region from Wayne and 
Medina counties westward and northwestward to the 
Maumee river? Is it because of the underlying geological 
differences, or because of the direction of plant move- 
ment? Whatever the explanation, we need more facts 
concerning the conditions existing and the plant societies of 
both sorts of bogs. I am at present engaged on the tam- 
arack bogs and will greatly appreciate any information 
supplied me on the occurrence, drainage channels, area and 
floral peculiarities of any such bogs known to any members 
of the Academy, or their friends. 
I had hoped that our committee on cataloging streams, 
lakes and swamps would supply much valuable aid in locat- 
ing the remainder of the tamarack bogs now existing and 
possibly these hopes are yet to be realized. Certainly the 
present state of our accessible knowledge is quite deficient. 
While working in Williams county I kept seeking to 
find Spring Lake, which according to the large maps of the 
Geological Survey, should be near the boundary of North- 
west and Florence townships, that county. Finally some- 
body said that Spring Lake is simply the name of a post- 
office — there is no body of water there. 
In closing I beg again to request that you send me what 
information any of you can give me about the tamarack 
bogs in Ohio.
