 the tidier trunks (fius. | and -2). 



As opportunity occurred in tiie prooruss of the work, erect trees were extracted from 

 other beds in the section, in the hope of discovering another fossiliferous fovest ; but 

 with little positive result. \n a trunk, about lo inches in diameter, and standing in 

 Section XXVI. of Division 4, .Mr. A. T. IIii.l had found in 187G several .shells of 

 J'tipa vetnsta. This tree, which was unifonnly tilled with compact argillo-arenaceous 

 matter, was taken out, and a few additional Pitixf obtained, but no other remains; 

 and no other trees could 1)e seen in the bed (tig. -2). Another tree .standing in 

 Section XXIV., and 2 feet in diameter, was interesting in consecjuence of its well- 

 marked Stigmarian roots, and of its standing on the sloping edge of a partially 

 denuded shale (tig. 3). It contained no fossils.
