Art. XI.—On the upright Fossil Trees found at different 
levels in the Coal Strata of Cumberland, Nova WScotia ; 
by Cuaries Lyeux, Esq., F.G.8., F. R.S., &c. 
[Communicated to this Journal by the author.] 
Tur first notice of these fossil trees was published in 1829 by 
Mr. Richard Brown, in Haliburton’s Nova Scotia, at which time 
the erect trunks are described as extending through one bed of 
sandstone twelve feet thick. Their fossilization was attributed 
by Mr. Brown to the inundation of the ground on which the for- 
est stood. Mr. Lyell in 1842 saw similar upright trees at more 
than ten different levels, all placed at right angles to the planes of 
stratification, which are inclined at an angle of 24° to the S.S. W.
