Brontozoum. On the reversed surface of the same 
slab are found impressions, which were produced by a 
number of fragments of sticks, five or six inches long, 
lying at right angles, or nearly so. One of these 
sticks has been broken, and its pieces are slightly 
‘displaced from each other. Various other specimens 
contain the marks of sticks, or twigs of trees. The 
striae, so distinctly discernable in a number of these 
portions, having been compared with twigs of the 
existing coniferee (?), were found to resemble them. 
Some of these sticks show the appearance of incipient 
carbonization; yet the rock is sandstone, presenting, 
as already mentioned, distinct appearances of quartz, 
and other substances of which the arenaceous rocks 
are composed.
