above the base of the so-called Dakota and its position may be con- 
sidered an important one on account of its proximity to one of the 
areas where Professor Lesquereux obtained “a large number of 
fine specimens of fossil leaves,” a locality mentioned as covering 
about three acres of ground which in part of the work is given as 
about 8 miles from the Salina station, and again apparently the 
same locality is given as 8 miles above the mouth of the Salina river 
Professor Lesquereux’s failure to indicate accurately the localities 
from which the fossil plants described by him came, even when as 
in this case he visited the place himself, is well known. [If this 
locality be 8 miles above the mouth of the Saline river, it is probably 
not more than 2 miles above the Mentor outcrop just described and 
nearly in the same part of the terrane. This conclusion is ap- 
parently supported by the later statement of Professor Lesquereux 
that at this locality he “found the same species of vegetable remains 
distributed from the base to the top of the hills, the altitude being 
about 75 feet above high-water mark of the river." If again, it be 
8 miles from the Salina station it is also probably in the lower part 
of the Dakota sandstone. If these Mentor shells and part of the 
Dakota fossil plants occur at the same horizon then the position of 
that part of the Dakota sandstone in the Cretaceous system will 
need reconsideration. 
The greatest number of the Mentor fossil shells were found on 
the divide between Spring and Dry creeks to the southwest of Salina. 
Jn this region the outcrop nearest Salina is 11 miles to the south- 
west on the S. W. Cor. Sec. 10, Washington township, on the north- 
ern side of the ridge 3 miles south and 4 mile west of Bavaria. Men- 
tor fossils were found in very dark brown sandstone fragments by 
the road-side and the yellowish shales of the Wellington were ex- 
posed only a short distance below them. On the ridge some 5 or 8 
feet above the loose Mentor fossils a single loose specimen of a fossil 
Jeaf was found which by its angularity indicates that it had 
20 been carried far and it probably came from the rock composing 
the ridge which in lithologic appearance it closely resembles.
