illustrated, but much remains to be done in the Silurian and pre- 

 Oambnan country, and amongst the newer rocks of the east and 

 north ; the same may be said of the counties of Stafford, Derby, and 

 others of the North Midlands, except in Leicestershire, where, owino- 

 to the energy of the Leicester Philosophical Society and a few others" 

 a great deal has been effected in some parts of the county, particularly 

 m the classic ground of Charnwood Forest. Cheshire and Lancashire 

 have been taken in hand by the Liverpool Geological Society, but 

 much remams to be done in the large counties of Cumberland and 

 Westmoreland, and especially in Lakeland. Something has been 

 done in the Isle of Man, but the recent Survey work there requires 

 photographic illustration. 



Passing to Scotland, the more sensational regions of the lava 

 plateaux have been illustated by numerous sets, but the ground of 

 gneiss and schist in the North- West and of the Central Highlands 

 requires much new work ; the same might be said of the greater part 

 ot the Central Valley and the Southern Uplands. Mr. Kidston has 

 done good work in Stirling, Mr. Coates in Perth, and Mr. Goodchild 

 about Ldmburgh, but not much other systematic work has been 

 attenipted. The names of Professor Heddle, Mr. Harvie Brown 

 Mr. Howie, and Messrs. Valentine, should be mentioned as havin.^ 

 contributed to the Scottish part of the collection 



In Ireland, the Belfast Naturalists' Field Club was one of the first 

 ot the field clubs to undertake the definite collection of a set of 

 photographs to illustrate their own district, and to contribute the 

 proceeds to the central body ; their able contributors, amono-gt whom 

 It IS a pleasure to name Mr. Welch, Miss Andrews, Mr. Gray and 

 Mr. Stelfox, have done much towards a photographic survey of their 

 own county and those bordering it. Dr. Valentine Ball was instru- 

 mental m sending a set of prints illustrating the phenomena of the 

 ^"^'i^J* "i^ 1 "^^ Howth, near Dublin, while Dr. Tempest Anderson 

 and Mr. Lingley have done much good work. The rest of the M^ork 

 may be safely left in the hands of those energetic field clubs which 

 have begun so well, with the remark that such districts as the Wick- 

 low Mountains, the beautiful tract of Limerick, the areas of ancient 

 rocks in Galway and Mayo, and the Carboniferous and Old Bed 

 bandstone rocks of Kerry, are all, literally, awaiting development. 



in Lngland and Wales we would call especial attention to the 

 further photographing of the big boulders and ice-worn rocks which 

 are rapidly disappearing, to the Malverns, the Cheltenham Oolites 

 and those of Dorset and Wiltshire with their Cretaceous rocks, the 

 central Coalfields of England, the Lake Country and the Cheviots 

 the Dale district of Yorkshire, and the Southern and Central parts 

 ot Wales. ^ 



The future extension of the collection, like its past history, must 

 depend very largely on the local societies and field clubs These 

 bodies are always asking what work they can do that will employ 

 a good number of their members, and which, though not requirino- 

 too much technical knowledge, will really be a help in advancing 

 natural knowledge. This is the very class of work required, and
