CORRESPONDING SOCIETIES. 31 



a difficulty was soon experienced in finding reliable observers, and they 

 had consequently to be given up. Mr. Wa.tts had, however, at his request, 

 taken the matter up with regard to the Oldham reservoirs, and had been 

 at great pains to make trustworthy observations, which had received the 

 warm appi-oval of the Temperature Committee. 



Mr. M. H. Mills thought that it might be advantageous if similar 

 observations were extended to the temperature variations of underground 

 waters. 



Tbe Chairman explained that there was already a Committee of the 

 Association dealing with underground temperatures, and he suggested 

 that they might extend their work to water as well as soil. 



Meteorological Photography. — The Chairman stated that some progress 

 had been made during the year with the work of this Committee, and 

 they had been fortunate in obtaining some very good photographs of 

 clouds, lightning, frost effects, &c. These photographs were exhibited in 

 the meeting-room of Section A, and he invited the Delegates to inspect 

 them. A report of what had been thus far done would be presented 

 during the meeting, and he expressed the hope that the Delegates would 

 assist the Committee by securing the co-operation of amateur photo- 

 graphers throughout the country. 



Mr. Gushing presented two photographs showing the effects of a snow- 

 storm taken during the previous vrinter. 



Section C. 



Oeological Photography. — The Rev. J. O, Bevan announced that on 

 his representation the Woolhope Club had recently appointed a Committee 

 to deal with this subject, and he hoped that their efforts during the year 

 would be of use to the Geological Photographs Committee. 



Mr. O. W. Jeffs stated that the work of this Committee, of which he was 

 Secretary, had made satisfactory progress during the year, and he ex- 

 pressed his thanks to the Corresponding Societies not only for the assist- 

 ance which they had rendered by supplying photographs, but also for 

 the interest which they had raised in different parts of the country. 

 As a result of the work an exhibition of photographs had been arranged 

 in the meeting-room of Section G. The total number of photographs 

 received during the year was 300. "With respect to amateur photographic 

 societies Mr. Jeffs stated that their Committee had not yet received from 

 them the assistance which they had hoped. Although a large number of 

 people in England, Scotland, Ireland, and Wales had helped them, it was 

 necessary to point out that what was now wanted was work of a more 

 systematic character. The Yorkshire Naturalists' Union had sent in the 

 largest number of photographs received from any one society. The Bast 

 Kent Natural History Society had also formed a photographic section and 

 had sent in the results, but in other parts of the country work had not 

 been carried on to the same extent, and he hoped that some of the 

 Delegates would advocate their cause and promote local photographic 

 surveys on a systematic plan. 



Mr. Wm. Gray remarked that the Committee must not be discouraged 

 by the limited number of photographs which might be sent in during any 

 particular year, because at the present stage, when the whole scheme was 

 being organised, the number of photographs did not indicate the amount 

 of work that was being done. Thus the Belfast Naturalists' Field Club
