the great importance of the subject. Mr. Jeffs had already recorded a 
number of photographs, and this was a suitable matter for the local 
societies, for there were many local circumstances to be dealt with, and 
the best mode of photographing, the best time, and so forth, could only 
be dealt with by people living on the spot. Ail the Delegates would feel 
that this was a subject they could represent to their Societies as one 
which should be carried out. 
Mr. Gray said there were erratic blocks in Ireland, particularly in the 
north; he did not know whether these blocks had been recorded, but if 
such a catalogue would be of any assistance to Mr. De Rance he would 
be glad to undertake its preparation for Antrim, Down, and Derry. 
Mr. Topley said there should certainly be a record of the boulders of 
Treland, but he was afraid the present Committee only referred to the erratic 
blocks of England and Wales ; it would, however, be very easy to extend it 
"next year if Mr. Gray would forward the information to Dr. Crosskey, 
and if that gentleman were not prepared to take charge of it another 
Committee could be formed. 
Mr. De Rance stated, with respect to the question of erratic blocks, 
that as Dr. Crosskey was not present, and as he had had some con- 
versation with that gentleman on the question of including Ireland, he 
would venture to suggest that it was first of all exceedingly important 
and necessary that the boulders of Ireland should be recorded in the 
same manner as in England; secondly, as it was too late this year to 
include the Irish with the already existing English Committee, a Com- 
mittee could easily be formed by Mr. Gray himself, or by cthers in Ireland 
who would undertake the inquiry. It should follow the lines, and the 
questions should be put in the same way as that adopted by the English 
Committee on Erratic Boulders. At the meeting at Leeds the Irish Com- 
mittee could, he thought, be amalgamated with the English one; it would 
then be a general Boulder Committee, and the reports might be taken to- 
gether or separately, and the facts collected during the year would make 
the first report. 
Professor Lebour, referring to the subject of Geological Photography, 
said that, as Mr. De Rance had already mentioned, Section C, since the 
first Conference, had had this matter referred to them for consideration, 
and he might say there was the greatest possible unanimity when it was 
brought up. The subject was one which all geologists would agree was 
a most useful one. Mr. Jeffs, as a member of Section C, explained the 
system which he and Mr. Adamson had so far adopted ; that method was 
regarded as no doubt a good one, but the whole question of detail was left 
to the Committee to report upon. He might say that it had been passed 
on to the Committee of Recommendations that same day. The members 
of the Committee were Professor Geikie (Chairman), Professor Bonney, 
Mr. A.S. Reid, Mr. S. A. Adamson, Professor Boyd Dawkins, Mr. W. Gray, 
and Mr. Jeffs as Secretary. He thought they would see that the Com- 
mittee was chosen with some thought as representing different parts of the 
country, so that a considerable area would be covered, and the different 
features of the various districts would not be overlooked. The Committee 
was not only appointed to do the work of collecting, preserving, and regis- 
tering in a systematic way the photographs of places of geological interest, 
geological sections, and so on, but he thought in the first instance it was 
chiefly for the purpose of seeing how the work could best be carried on in 
the future, and one of the most important points they would have to con-
