The following notes are contributed by Mr. A. R. Horwoop, of the 
Leicester Museum :— 
Distribution of Erratic Blocks in the Drift of Leicestershire. 
These notes are supplementary to those previously published by 
Messrs. PLANT and others, recorded in earlier reports upon the Erratic 
Blocks, and to the summary compiled by Mr. C. Fox-Srraneways, F.G.S., 
in ‘Geology of the Country around Leicester,’ 1903, pp. 59-60 (‘Mem. 
Geol. Surv. Explanation of Sheet 156’). 
The notes are best arranged according to localities, and these have 
been grouped together in the drainage areas to which they respectively 
belong. For it is clear that the present valleys are simply preglacial 
valleys which have heen traversed by glaciers, leaving their accumulations 
of boulder clays, sands and gravels in these same valleys, and also in 
plateau form upon the hills. The source of the boulders, either from the 
north-west or north-east, is sufficiently clear to those conversant with the 
different boulder clays and the characteristic erratics of each.
