any bold, rocky exposure in the landscape, for vegetation covers every 
thing. 
Gas springs are known in this township; the one on Mr. Z. White’s 
land, one-third of a mile north-west of Weymouth, being the most east- 
erly observed in the county. The gas comes from a spring of water 
which has never been known to freeze over. Another gas spring is in 
the bed of the west branch of Rocky River, three miles north of Medina 
village and west of the turnpike bridge. 
An ancient fort, just south of the business houses of Wega, is one 
of the best preserved and most interesting of its kind which can be seen 
in this region. Like other such evidences of the old power and import- 
ance of the race of men known as the mound-builders, this fortification 
is called an Indian fort, though the Indians which the early settlers ot 
the country found, knew nothing of these ancient works of defense. 
How could they when the maple trees growing on the embankment gave 
€vidence of being over seven hundred years old? The fort is an in- 
trenched projection of land, which has abrupt, bluff outlines, excepting 
at its rear connection with the main land. The river having made an 
abrupt turn, back upon itself, there was formed a peninsula-like projection 
of land having shale blufis over fifty feet high. The defense of this 
point was easy after trenches had been cut across the neck. Three such 
trenches are now plainiy discernible, and they bear on the surface evi- 
dence of the former greatness of the work. The trenches are two hun- 
dred and ten feet long (width of the point of land); the inner trench is 
three hundred and sixty feet back from the end of the point; the middle 
trench is forty-one feet from the inner one; and the outer trench is forty- 
nine feet from the middle one, or four hundred and fifty feet from the 
end of the point. The trenches run east and west, the point of land 
being a southward projection. Hven now, after these many centuries of 
change, the average depth of the trenches is three feet, while in some 
places it is five to six feet, the embankment projecting above the general 
level of the land about two feet, making the bottoms of the trenches be- 
low the tops of the embankments five feet, and in places seven feet. 
Harly settlers of the township thought this high point of land, this old 
fortification, a superior place for a burying ground, and it was used for 
this purpose for some years; a few of the brown stone slabs still stand as 
reminders of the pioneer whites who dispossessed the red man of this 
territory, which had once supported the the semi-civilized mound- 
builders. To get at the cemetery a road was cut through the center of 
the three embankments. The Clinton Line Railroad (never built) was 
to have passed just in the rear of the other trench, and some excavation
