SKETCH SOIL MAP. 
The map, which has been most kindly prepared and coloured for 
‘The Naturalist’? by Mr. A. J. Jukes-Browne, of the Geological 
Survey, is a sketch, as far as the scale will allow, of the soils of the 
County. Five classes are represented in colours as follows :— 
Brown—Alluvium, Peat, and Fen soils. 
Blue—Clay soils. 
Pink—Gravel aes i soils. 
Green—Chalky 
alow: Tigiebeed en 
It is not a geological or drift map—though based on the maps of 
the Geological Survey—as the following short, but far from full, 
analysis will show. The Svewz or Alluvium, Peat, and Fen soils 
often include isolated patches of ira or sand, and small out- 
croppings of the older embedded strata. This same rule of sm 
included out-crops and isolated patches applies to every colour 
division of the map. The 2/ue* or Clay soils include the Clays of the 
* The Red Keuper Marls of the Isle of Axholme (Nat. Hist. Div. 1) are 
‘coloured Ai/ve in the map, but owing to the fact that lime enters into their com- 
position, the Flora approximates to that of the Oolitic Yinseanlaia (the Fellow of 
the map) rather than to that of the Boulder and other Clays.
