. No. 18. A beautiful example of a Scandinavian, garnet- 
iferous mica-schist. The garnets stand out boldly, though they 
have got bruised with knocking about on the beach. 
o. 19. A much-weathered specimen; apparently a garnet- 
iferous schist, showing the holes which the garnets, which have 
decomposed, once occupied. 
o arboniferous limestone, metamorphosed by 
roc 
Teesdale, etc. On applying hydrochloric acid to this rock it 
slightly effervesces. 
With regard to two of the above specimens, Me. P. F. Kendall, 
of the Yorkshire College, Leeds, who is examining them, thinks 
they may be of more than ordinary interest; and should this turn 
Out to be the case, an account of them will appear hereafter. 
Mr. Sheppard, in his report, further remarks that ‘though 
the probability is they have come from the boulder clay, the fact 
must not be lost sight of that they are beach specimens’ in 
recording them 
This viral I thoroughly endorse and appreciate; and 
having regard, also, to the doubts that have been thrown out as 
to these rock fragments occurring where they are found in a 
natural way, I have gone somewhat fully into the matter. 
I might, I think, be excused if I dismissed the theory of the 
Stones in question having been thrown out ‘as ballast by the 
fishing boats’ as untenable, but as this fact has been stated, 
recently, in the pages of ‘The Naturalist,’ I am bound to take 
notice of it. There are but few fishing boats at Sutton—not 
half-a-dozen, I believe—and no ports or landing-stages exist on 
this part of the coast. Occasionally an old hulk floats ashore to 
be broken up, and from it, possibly, some ballast might be thrown 
out, but the erratics I allude to are not of this nature. They 
consist, as I have said, of stones and pebbles (such as are found 
on the Holderness coast), and they are met with, not only at 
Sutton, but all along the shore to Chapel, where they abound, 
and on to, and beyond, Skegness ; and it would require fleets 
of ballast-discharging boats to meet such a supply. On this 
point, see also the Geol. Mag. (1894, pp- 334, 477, 565, where 
Mr. Harker has fully discussed the subje ect). 
Before going further, let me again call attention to the fact 
that the display of stones on this coast depends very materially 
on the state of the sands. I have been at Sutton frequently, 
and never saw the stones in such cearloae as in se tiie last, 
May ; 1898.
