PLATE XLIII 
Note on sources of Geologic Map of Giles Co. 
This map was compiled from (1) Watson’s State Geologic Map of Vir- 
ginia, (2) a map issued with Stose & Miser’s “Manganese Deposits,” (3) an 
old map by J. J. Stevenson, published in Transactions of Amer. Philosophical 
Society and (4) the work of the Class of 1922. 
The manuscript maps by other classes were not used because this map 
was completed before the accompanying manuscript had taken its present 
form. The additional data on other MSS. maps would not make much 
difference in a map on this scale and refinement but in a larger scale map 
with formational units several areas of Romney, Giles, and Rockwood must 
be changed. The authors.
