22 GLAUCUS; OR, 
the same stuff as those said rocks, Step into the 
next field and see. That rock is the common 
Snowdon slate, which we see everywhere. The two 
shoulders of down, right and left, are slate, too; 
you can see that at a glance. But the stones of 
the pebble bank are a close-grained, yellow-spotted 
rock. They are Syenite; and (you may believe 
me or not, as you will) they were once upon a 
time in the condition of a hasty pudding heated to 
some 800 degrees of Fahrenheit, and in that con- 
dition shoved their way up somewhere or other 
through these slates. But where? whence on earth 
did these Syenite pebbles come? Let us walk 
round to the cliff on the opposite side and see. 
It is worth while; for even if my guess be wrong, 
there is good spinning with a brass minnow round 
the angles of the rocks. 
Now see. Between the cliff-foot and the sloping 
down is a crack, ending in a gully; the nearer side 
is of slate, and the further side, the cliff itself, is 
—why, the whole cliff is composed of the very 
same stone as the pebble ridga.
