The books, too, which are kept specially for climbing records at some places in the Lakes, such as Dungeon Gill, Buttermere, and, notably, Wastdale Head, are misleading, owing to the widely different standards of difficulty among the various writers. Printed accounts are so few that this objection hardly applies to them. The most noteworthy beyond all doubt are the two articles written for _All the Year Round_, in November 1884, by Mr. C.N. Williamson, the late editor of _Black and White_. It would be hard to exaggerate the effect which these articles had in making the Lake climbs known. The same writer had previously contributed articles of less permanent value to the _Graphic_ and the _Daily News_. In 1837 two articles had appeared in the _Penny Magazine_ (see _Lord's Rake_); in 1859 the late Professor Tyndall had written of _Mickledoor_ in the _Saturday Review_, and more recently articles have appeared in the _Pall Mall Gazette_, by Mr. W. Brunskill and by Mr. H. A. Gwynne. The present writer contributed an article to the _Alpine Journal_ of August 1892, and one containing very clear illustrations of 'back-and-knee' work and of an episode in the long climb on the Pillar Rock to the pages of _Black and White_, in June 1892, while numerous articles have appeared from time to time in such local papers as the _Whitehaven News_ and the _West Cumberland Times_, and in the Manchester, Leeds, and Bradford press. Of guidebooks the only one of any value to climbers is Mr. Herman Prior's 'Pedestrian Guide.' Any value which the present book may have is largely due to the excellent drawings of Mr. Ellis Carr, who most kindly came forward to fill the place left by the lamented death of Professor A.M. Marshall. Much assistance has been derived from sketches and photographs kindly lent, those of Mr. Abraham, of Keswick, being especially useful. For the valuable article on 'Chalk' I am indebted to Mr. A.F. Mummery, whose knowledge of the subject is unrivalled; while Mr. J.W. Robinson, of Lorton, has zealously assisted in all matters connected with Cumberland; and I must gratefully acknowledge help given in other ways by Mr. J.E. Morris and the Rev. C.J. Buckmaster. CLIMBING IN THE BRITISH ISLES ENGLAND =Alum Pot=, the name of which is also found in such forms as _Allen_ and _Hellan_, lies just west of the Midland Railway, about halfway between Horton and Ribblehead stations, and on the north-east side of Ingleborough. It is one of the most striking and most famous of the Yorkshire potholes, being an elliptical opening in the limestone, 120 ft. long and 40 ft. wide, with a perpendicular depth of 200 ft. The exploration of it was begun by Mr. Birkbeck of Anley in 1847, who, assisted by Prof. Boyd Dawkins and a large party including three ladies, made a complete examination in 1870.
