or so along the bank of the stream. The general direction of the dip 
is northwest — N. from 30° to 45° W. It was estimated that the thick- 
ness of the deposits in sight is at least 500 feet. The fossils are in the 
more shaly and thinner-bedded layers near the top of the exposure, 
between heavy-bedded sandstones, which in some cases show traces of 
plants, but generally are barren. Fossils occur in the more arenaceous 
beds, as is shown by their discovery in loose blocks in the neighborhood, 
but such fossiliferous sandstones were not discovered in place.

Edmunds Hill. — In the northern part of Chapman Township, just 
south of the northern boundary, the Chapman sandstone is exposed in 
the lower part of Edmunds Hill (1099 C). The whole base of the hill 
appears to be of sandstone and the cap is of igneous rock. The sand- 
stone at this point is brownish to gray in color, from very tine to 
medium grained, and from shaly, thin layers to massive and thick 
bedded. Some of the same species are found at this and the more 
southern locality, while some species collected at Edmunds Hill have 
not been seen elsewhere.

Presque Isle and Mars Hill. — In addition to the above, several loose 
blocks were found along the roads in Presque Isle and Chapman, and 
one at the foot of Mars Hill, which have been marked 1099 B 1, 2, 3, 
4, and 5. These contain the following species:
