to deal with them properly. Judging by the length of his reply 
and the ground covered by it, the estimate is no doubt a moderate 
one. I shall therefore, to save time and space, refer Mr. Kendall 
to the numerous papers of mine on glacial geology which, at his 
request, I some time since presented him with. 
Mr. Kendall’s reply deals only with two sections of the subject, 
viz.. the Distribution of Erratics and the Molluscan remains. J 
presume they have been selected as his strongest points, and I was 
in hopes to have gained some important information in the way 
of facts that would be helpful in any honest attempt to interpret 
the phenomena. Instead of this I find that information well known 
to glacial geologists, through the labours of Mackintosh and others, 
including myself, trotted out as if it were new. These facts of 
distribution are, in my opinion, as I have frequently explained, quite 
irreconcilable with the Irish Sea Glacier hypothesis. Mr. Kendall 
seems to think that if he can show any grouping of boulders in the 
Boulder-clay, or indeed anywhere on the drift area, he has a 
sufficient answer to my criticisms; and in proof of this grouping 
he quotes as authorities the observations of yeologists whose ex- 
periences are much newer even than the new geology. Although 
not prepared to accept Mr. Kendall’s ipse diait on the points either 
of grouping or proportionate distribution of erratics, 1 have not the 
slightest indisposition, for the sake of argument, to granting him all 
he states. It is perhaps not a sign of generosity on my part, for 
the reason that it does not, in my opinion, alter the bearing of the 
evidence at all. 
It is admitted that Lake District rocks, together with Scotch rocks, 
are found in greater or less proportion all the way from Macclesfield 
to Moel Tryfaen. It has never been explained on the Ivish Sea glacier 
hypothesis how they come to be distributed and intermixed over 
such a wide area, and this is the information I have in vain been 
seeking. In Dr. Wright’s book it is very clearly shown (pp. 58-60) 
how the Alpine boulders found on the Jura were proved by Guyot 
to have been conveyed to their positions by a glacier. The proof 
was simple and convincing. All the boulders derived from the right 
side of the Rhone clung to that side, while all the boulders derived 
from the left side clung to the left side, and neither the one nor the 
other crossed over. If all the Lake District rocks were found in a 
trail from Cumberland to Macclesfield, and the Scotch rocks in 
a trail from Wigtown or Dumfries to Carnarvonshire and none crossed 
over, the Irish Sea glacier would ‘‘score.” This is not the case; the 
rocks occur over the whole area even according to the new glacialists 
and are inextricably intermingled at all horizons according to my 
observations. 
Until information is given which will harmonise these observa- 
tions with the work of the Irish Sea glacier as conceived by its 
latest supporters,’ it seems a waste of paper and printing ink to 
1 In this connection the communication from Mr. Deeley (Grou. Mae. p. 573-4), 
is well worth studying.
