ee Mather further stated, that the bowlders of Ohio were 
in continuous lines and groups, and not scattered promiscuously. 
On the river St. Peter’s, the bowlders may be seen extending for 
miles, “as along a coast line; in some situations one might see 
them bounding the horizon as far as the eye could reach.

r. Locke, in conformity with Lt. Mather’s statements, men- 
tioned a region of bowlders in Ohio, extending from the town of 
Eaton quite across the state ; five miles in width and over forty 
in extent. 
Dr. C. T.. Jackson remarked: that the phenomena of diluvial 
currents were well exhibited in the vicinity of Providence, at 
Cumberland, R. I. A large mass or mountain of porphyritic 
titaniferous ion of very peculiar character exists in that place ; 
to the north of it no bowlders are to be found, but on the south, 
huge bowlders of it may be seen, and so Rbundastt that the stone 
are a ilt - them ; and below, at Papoose Squash Neck, small 
's of the same characteristic rock are found ; south of New- 
port, iad: i filtther south, the same are met With of a smaller 
size, the whole extending from north to south forty miles, and 
from six to fifteen in width, diverging to the south. 
The characteristic macle revit Lancaster, Mass., presents sim- 
ilar phenomena, being found in loose masses to the south as far 
as Bolton, while none can be found to the north of the locality. 
He considered the power of the diluvial currrent greater to the 
north than at the south, since the evidences of it in Maine are 
much greater than in Rhode Island; bowlders have been found 
on Mount Katadin as high up as Sins thousand feet ; he thought 
there was no evidence of any elevation of the coke after the di- 
luvial current had passed. 
Mr. Nicollet proposed, at a future meeting, to make some Te- 
marks upon, and to exhibit specimens from, the cretaceous for 
mation on the upper Missouri. 
Mr. Redfield expressed a wish that the attention of the Ass 
ciation should, at some convenient time, be called to the recent 
formation along the eastern coast of the United States.

Mr. Richard C. Taylor, for the purpose of viewing a model of
