This locality is a cut on the Baltimore and Ohio Railroad about a 

 mile east of Relay and immediately west of the hridjie where that I'oad 

 passes over the Baltimor(» and Potomac Tiailroad. It is at the foot of 

 a considerable hill, known as Vinegar Hill, which rises lo the north of 

 that point. The precise spot is nearly midway of tlie cut, though 

 somewhat nearer its western end, on the north side of the tracks, lieein- 

 ning about G feet above the tracks and having a thickness of 4 feet. 

 The watei- has here worn a small gulch, in the sides and Ixjttom of which 

 the plants occur. It was discovered by Mr. Arthui' Bil)bins, wlio, in 

 October, 1895, made a considerable collection from it for the Woman's 

 College of Baltimore. One specimen was collected by Mr. Bibbins on 

 September 1, 1896, and the next day (September 2, 1896) a good col- 

 lection was made by Mr. Bibbins and Professor Ward. This collection 

 is deposited in the National Museum. 



The fossiliferous rock material from this locality differs from that 

 of all the others, though some of it closely resembles that of Federal 

 Hill in Baltimore. It is a friable, fine-grained, sandy clay, with an 

 imperfect cleavage, which is, however, better than that of the material 

 from the other localities. Hence the preservation is better. But here 

 also only small fragments of plants seem to have been preserved, prob- 

 ably owing to the fact that the place of entombment was remote from 

 the place of growth. The plants in it are fairly well preserved as a 

 rule, and some are quite distinct. As, however, the material is soft 

 and friable, the plant impressions are easily destroyed.
