Facts relating to Dilwvial Action. 247 
for half a mile, and sisal dite in the low grounds, the 
furrows turned due east, and after passing the obstruction, again turn- 
ed north east, or east. Not a mile from the same place, on descend- 
ing from the same high ground, the furrows run east, tallying with the 
face of the hill. On the high lands west of the Shongham and where 
there could be no obstruction for seventy or eighty miles, I examined 
ten or twelve different places in which the furrows were deep and 
distinct, and found them to run from ten to twelve degrees north of 
east, and they continued in the same direction for a considerable dis- 
tance down the mountain; at no great distance to the south, the 
furrows tended twenty-five degrees south of east, leading to a low 
_ Opening in Shongham mountain, through which the currents of water 
naturally run. I have rarely examined the strata below the de- 
composing effects of frost, without discovering distinct traces of di- 
luvial action. Near the banks of streams, I hardly ever found any 
such marks, but the solid strata appeared broken and very little 
altered by attrition. In one place where the earth was removed 
and where there was no visible obstacle to alter the current of water; 
the furrows crossed each other, shewing that the current took a new 
direction, after the first furrows were made. About twelve or four- 
teen miles west of Newburgh, I found the marks on the solid gray- 
wacke to run nearly north and south. At Coxakie, in Green County, 
in digging a well and coming to the solid strata, the furrows ran 
northerly and southerly about in the direction of the mountain. I 
found that in different places, between thirty and forty miles apart, the 
furrows ran about ten degrees north of east, especially where the 
current had a free course for any considerable distance without any 
obstacle. Where the solid strata remained, but a part has been re+

Asof frequent occurrence. On the high land, as well as on the low, 
the furrows appear near: small streams, in every possible situation, 
showing, without a doubt, that the rivers and hills remain now as they 
Were before the flood. Pieces of the solid strata with the furrows 
on them, are often found where part of the strata was broken 
up-after the furrows were made, but more of the argillite than
