No sticks or stems nor impressions of such were found in these lower 
rocks, large blocks of which have become detached and lie isolated at 
the foot of the cliff, but one of the large projecting crags has a peculiar 
horizontal perforation parallel to the beach. It is triangular in shape and 
large enough for the arm to be thrust in at either end, but the tube is not 
straight so that light cannot be seen through it, although it seems to be 
continuous. It is five or six feet long and has the appearance of having 
been produced by a crooked log or stick, the substance of which has 
disintegrated and disappeared. 
But for the green glauconitic clay pockets there would be no trouble in 
considering Nos. 1 and 2 as Potomac. No 3 is the most puzzling, and it 
is very hard to decide where to place it. No. 4 is the most distinct & 
satisfactory and continuous without

interruption along the entire face of the cliff, not having any appearance 
of being a lens, though varying in thickness from two to 5 or six feet. As 
to the Columbia, through [[insertion] A ou [[/insertion]] t this entire region 
the brick clay is usually underlain by a bed of pebbles or cobble, which 
must, I suppose, be distinguished from the boulder member, supposed 
to be younger. It can hardly represent the Lafayette, as it occurs at the 
water's edge as well as at the top of the cliff, and is doubtless due to the 
assorting conditions of deposition that existed at the time. 
Above the log-slide the bluffs rise still higher, reaching nearly or quite 
100 feet at the highest point of which a rough section was given on Nov. 
20. In that section I put the present Nos. 1 & 2 together under Potomac 
and Nos. 3 & 4 together under Tertiary. The cliff is too steep to scale 
and my examination was less close and minute. The present section is 
the result of a thorough inspection of every part and
