 In working away the pillars of Coal in this district of the colliery, 

 viz. about half a mile south from the Burraton Engine Pit, and about 

 two miles due north from the village of Long Benton, the superincum- 

 bent strata falling down, exposed the fossil stem presented, in the situa- 

 tion, as shewn by the accompanying sketch ; and on a further, and 

 more minute examination of the different parts of the workings, a great 

 many more were discovered that had before escaped notice ; and as the 

 real position of these stems seemed an object of great interest to Natu- 

 ral History, the strata were worked away until the top of the stem was 

 reached. The specimen presented was much broken by the crushed 

 strata occasioned by the working of the pillars, but on tracing some 

 more of these stems where the beds were not so broken, I found this 

 was the most perfect we could obtain. The bed. No. 1, of the Section, 

 being compact, contains very few vegetable impressions, though it is 

 by no means destitute of them, but between it and No. 2 is a smooth 

 and perfect parting noticed before, as called the "black parting," the 

 face of which is literally covered with vegetable impressions, a few of 

 which I take the liberty of presenting to the Society. For some dis- 

 tance upwards from this parting, a considerable quantity of these im- 

 pressions exist, but they become more scarce towards the middle and 

 top ; and in the Post girdle few, if any, except the larger stems similar 

 to that presented, are found. 



The accompanying figures, (Plate XIX.,) will shew the position of the
