116 HISTORY OF THE COUNTY BOTANY OF WORCESTER. May, 1892. 
and what is there in the way of mining waste which is more 
absolutely and defiantly unpicturesque than slate ? It remains 
so clean and fresh-looking, there seems no chance of friendly 
moss or lichen covering, at any rate within reasonable time, 
its staring ugliness. No ferns hide in the interstices as in 
those of the limestone waste of many of our lead mines, and 
altogether blast furnace slag heaps seem to me distinctly less 
obtrusively ugly. However, passing down the valley, we 
came in sight of what Sir A. Ramsay describes as one of the 
finest displays of ice action to be seen in Wales. We thought 
we had seen a good deal during our little walk, but certainly 
here we had come upon something which eclipsed it all. 
The grooving and rounding of the hillsides and the perched 
blocks abound on every hand, and the valley certainly should 
be visited by anyone interested in glacial matters. 
At Tan-y-Grisiau our walk ended, and only those who 
have had a similar week, with just enough gentle scientific 
and natural history interest to keep them always on the 
watch, can understand the pleasure with which we look back 
to it.
