Mentor fossils are usually found in loose fragments of dark 
brown to reddish sandstone scattered on the slopes of low 
rounded hills over a considerable part of Saline county, or both 
sides of the Smoky Hill river. The type locality or at least 
the one nearest Mentor is four miles east of this village, on 
the east side of the river. Two miles south of this locality is a 
ledge of oyster shells very like those contained in the Kiowa 
of the Belvidere region. Mentor fossils were found a few feet 
above the oyster bed. P'ive miles north of Salina is an interest- 
ing locality where several species of Unio and other fresh- 
water forms were found. The most numerous localities, how- 
ever, are southwestof Salina in the region between Bavaria and 
the Smoky Hill buttes, on the divide between Spring and Dry 
creeks. A number of localities are mentioned by professor 
Prosser.* Professor A. W. Jones, who has the advantage of 
living in the region, has been mapping the area for some time 
and locating the various places which yield Mentor fossils. 
Professor Jones' report will doubtless add much to our knowl- 
edge of the localities. He states that the Mentor beds are 
found in northern McPherson, Ellsworth, Lincoln, Ottawa and 
Clay counties, f 
Mr. P. G. Hall who was mentioned by professor Prosser,^: 
kindly conducted Dr. Ward, Dr. Stanton and the writer to a 
locality where professor Mudge collected fossils in 1878. Mr. 
Hall, who, at that time was a boy herding cattle on the range, 
remembers the professor as a "kindly old man who was knock-
