60 TRANSACTIONS OF THE WAGNER FREE 



The above remarks remain applicable to the facts of the present day, 

 and require little or no modification except in so far as more recently 

 obtained data permit us to emphasize with greater positiveness certain 

 points that had hitherto remained in a measure conjectural. Thus, the 

 very extensive inter-association of the nuinmulitcs with Orbitoidcs cphip- 

 f it/in leaves practically no doubt that the formation in question is not 

 Upper Eocene, but Oligocene ; and secondly, the finding of nummulites 

 in situ at a locality some fifteen miles northeast of the original locality, 

 and, again, five miles southwest of Gainesville, enables us to locate within 

 definite limits the partial boundaries of the formation. 



We were informed that an outcrop of the rock occurs in a morass 

 about a half-mile or more inland from Loenecker's, but the lateness of the 

 hour at the time of our visit, and the difficulty of reaching an unknown 

 spot practically inaccessible in the heart of the wilderness, prevented us 

 from making a search in that direction. About a mile and a-half above 

 Loenecker's a mass of rock juts out from the bottom of the river-channel 

 to within a few inches of the water's surface, in one or two spots rising 

 slightly above it. Much to our surprise we found it to be almost entirely 

 destitute of fossil remains, showing not a trace of either of the genera of 

 Foraminifera so abundant in the rock below. Its stratigraphical relations 

 could not be definitely ascertained, but without much question it is a 

 member of the nummulitic series of deposits, and may be a near equiva- 

 lent of a similar looking rock that appears on the beach at Clearwater, 

 immediately north of the wharf. The fossil impressions are very 

 obscure, and such as we observed can only doubtfully be referred to 

 Cytherea and Modiola. 







ROCKS OF THE PITH LAC HASCOOTIE. I was unable to make a personal 

 exploration of the rocks of this region, and am, therefore, compelled to 

 confine my remarks to an examination of rock specimens brought to me 

 by Mr. Willcox, and to this gentleman's references bearing on their 

 occurrence. The rock is a tough, partially siliceous, white limestone, in 

 places densely charged with fossils. These are mainly in the form of 

 casts of minute gasteropods, probably one or more species of Cerithium, 

 among which I failed to find any species that we had observed elsewhere; 

 the question of age is thus left undetermined, although a strong proba- 

 bility argues in favor of the Oligocene. According to Mr. Willcox the 

 shores of the Pithlachascootie are in places rocky for a distance of two 

 or three miles from the mouth, the bluffs rising 6-8 feet above the water, 

 consequently higher than in the case of most of the western streams. 

 Where the bank rises higher than three or four feet, it slopes back and 

 is covered with soil. Thq fossiliferous beds were found to extend to a 

 height of about three feet above the surface of the water, appearing in
