sion does not necessarily follow, as is evinced by the facts over

Montreal may have had the same origin as the so-called beaches 
that rise several hundred feet higher in the State of Ohio,” his lan- 
guage is ambiguous; but interpreting it by the context it is 
wrong, if we may trust Logan, Dawson, and others, who have 
studied those high St. Lawrence “ beaches ;” for these geologists 
describe them as true sea beaches and under-water marine depos- 
its, containing marine shells, and some of the beds, as | know from 
that the Continental Interior, farther west, participated in the sub- 
sidence; and yet this may have been a fact. Whether so or not 
facts that will demonstrate the truth are difficult to find over the 
interior of a wide continent, and hence a uniform opinion among 
geologists may never be reache J.D. Dz
