MOVEME^TS OF UNDEKUKOUND ^^■ATERS OF NOKTIMVEST YOKKSUIHE. 229 



On the occasion of their last visit to the district your Committee 

 hurriedly explorpd a cave which they had not previously seen, and are of 

 opinion that it offers remarkable facilities for the further study of the 

 development of underground watercourses, inasmuch as it exhibits tribu- 

 tary and deserted passages in every stage of development and decay. 



In order to enable them to further prosecute the study of this most 

 interesting question your Committee hopes that it will be granted a 

 new lease of life, and therefore asks to be reappointed with a further 

 grant. 



The members of the Committee wish to tender their thanks to Mr. 

 Theodore Ashley, of Leeds, mine surveyor, who, though not a member 

 of either of the comuuttees, has given much time and care to the investi- 

 gation.

 Beport of the Cmnmitiee, consisting of Professor James Geikie 

 (Chairman)^ Professor W. W. Watts (Secreiarn), Professor T. G.

The Committee have to report that during the year 412 new photographs 

 have been received, bringing the total number in the collection to 3,308. 

 This is the largest number of new photographs ever recorded in a single 

 year, and the annual average number of photographs recorded for each 

 of the thirteen years of the Conmiittee's existence now reaches 254. 



The usual geographical scheme is appended. There are no new coun- 

 ties in the list, but the following are now very well represented : — Cumber- 

 land, Devon, Gloucester, Leicester, Somerset, and Westmorland, while 

 Suffolk, Glamorgan, Banff, Fermanagh, and Sligo are beginning to be 

 better illustrated. There are, however, several counties, many of them 

 mentioned in previous reports, still entirely unrepresented in the collec- 

 tion. 



Several improvements are noticeable in this year's accessions. In the 

 first place, instead of isolated photographs the Committee are receiving an 

 increasing proportion of groups, each illusti-ating some special point, some 

 defined area, or S(,'me particular piece of work. Thus Mr. Bingley sends 

 a series illustrating Professor Kendall's work on the Glaciation of the 

 Cleveland Hills, recently published by the Geological Society. He also 

 continues his Yorkshire Coast series and those from theMagnesian Lime- 

 stone district. Mr. A. S. Peid's set shows the development of joint-caves 

 by marine denudation. Charnwood Forest is the subject of most useful 

 sets by Dr. Meadows, Mr. Harrison, Mr. Hodson, Mr. Coomaraswamy, 

 and Mr. Levi. The Geologists' Association excursions have also produced 

 a Gower series by Mr. Coomaraswamy, and numerous isolated prints by 

 himself and other geologists. Professor Reynolds sends sets taken along 

 a new railway in Gloucestershire, and groups from South Devon, Glouces- 

 tershire, and Somerset,
