VI. 
ON GEOLOGICAL PHOTOGRAPHY IN HERTFORDSHIRE. 
By John Hopkinsox, F.L.S., F.G.S., etc. 
Head at St. Albans , 1 6th April , 1890. 
At the meeting of the British Association held at Bath in 1888 
Air. Osmund W. Jeffs read a paper before Section C (Geology) 
on “Local Geological Photography,” in which he suggested the 
desirability of making a collection of photographs illustrative of 
the geological features of each county. 
The matter was referred, by the Committee of Section C, to the 
Conference of Delegates, and at the meeting of the Conference on 
the 18th of September, Professor Lebonr, as representative of this 
Committee, informed the Delegates that it was proposed to appoint 
a Committee to collect and register local geological photographs, 
but that the proposal was then so indefinite that it could not be 
dealt with that year. “ It was hoped,” he said, “that Delegates of 
Corresponding Societies, by discussing the matter among themselves, 
would have it so organised and ready to place before, the Com¬ 
mittee of the Section next year .... that a Committee of the 
Association might be appointed, with a small grant, to work the 
scheme satisfactorily.” A number of rules, which he read, had 
been suggested for discussion by the Delegates, but the Committee 
of the Section did not wish to enforce too many restrictions as to 
uniformity. 
Mr. Jeffs then said that a large number of Societies in different 
parts of the kingdom had from time to time taken photographs of 
various geological sections and features as they came under their 
notice, but there had been no systematic way adopted either of 
collecting the photographs or of recording them, so that geologists 
interested might really know what had been taken. He thought 
that if some arrangement could be made a great deal of good might 
be done, not only for the benefit of geological science but also for 
educational purposes. 
A discussion ensued, in the course of which it was pointed out 
that the chief object was to secure photographs of typical and 
especially of temporary sections. 
In the following year, at the Newcastle meeting of the British 
Association, the subject was again brought before the Conference 
of Delegates, and Mr. Jeffs stated that he had communicated with 
the Delegates of the different geological societies in the kingdom, 
and now had a list of the geological photographs each society had 
obtained, and a large collection of photographs, which he exhibited. 
Subsequently, at the same meeting of the Association, a Com¬ 
mittee of seven members was appointed to arrange for the “ Col¬ 
lection, Preservation, and Systematic Begistration of Photographs 
of Geological Interest in the United Kingdom.” Professor James 
Geikie, F.B.S., is Chairman of this Committee, and Mr. Osmund 
AV. Jeffs is the Secretary.
