CARBONIFEROUS VEGETATION IN YORKSHIRE.” 
the writer of this paper is deeply indebted for his practical and kindly 
great importance was impressed upon the members of 
reporting all geological observations they might make, and the value 
of making notes upon, and sketches of, any section. What would seem 
unimportant at the time, might possibly be, after careful study and 
w 01 king out, a valuable discovery. Thus the accidental sight of a 
small portion of stigmarian roots by Messrs. Murgatroyd, certainly led 
to all the discoveries named; and, again, the visit of the members to 
the Hitchingstone really led to the formation of the Yorkshire 
Boulder Committee. These are cases in point, and should stimulate 
our members in the work of the future.
