Roger and Yard mines. We are enabled, by the kindness of 

 our friend Mr. William Hawkshead Talbot, to give the fol-

The thickness of the warren and white grit, as shown in 

 this section, differs from that obtained in the quarry ; but this 

 circumstance is easily accounted for, when we consider that in 

 the one case the section is from the deep, whilst in the other, 

 at the quarry, it is taken at the outcrop. 



On the discovery of the trees, hundreds of people visited 

 them, and the novelty of the occurrence, as well as their very 

 perfect state of preservation, had so far excited the ignorant 

 cupidity of many, that although every care was taken by the 

 proprietor of the quarry to preserve them, yet still individuals 

 found means to obtain portions of the roots, by placing ladders 

 against the perpendicular wall of rock beneath them at night, 

 and by this means mutilated them very considerabl3^ 



The tree on the north side of the quarry was about four 

 feet in length, cylindrical, decorticated, and about a foot in 

 thickness, not possessing any well-defined seams, but with 

 ribs and furrows, proving it to be a Sigillaria. At its base 

 there were no distinct roots, but in the clay underneath it 

 were numerous impressions, which were evidently those of 

 roots, and from which there emanated distinct and easily traced 

 fibrils or rootlets. 



The one occupying a central position in the quarry had been 

 removed, and was lying in a fragmentary state in an adjoining 

 quarry. Its diameter was about fifteen inches, and in form it 

 appeared to have been nearly cylindrical. The external sur- 

 face presented all the scars, ribs and furrows which commonly 

 appertain to Sigillaria reniformis, so much so as to induce the 

 authors to believe that the individual belonged to that species. 

 From information received from the workmen, this specimen 

 does not appear to have had any traces of roots. 



The individual situated on the south-west side of the quarry 

 was by far the largest and most perfect specimen, being ori- 

 ginally nine feet in height; two feet had however been re-
