TRANSACTIONS OF THE 



MISCELLANEOUS NOTES AS TO DIFFERENT MINES. 



As may be inferred from the configuration of this coal 

 field, the shafts are sunk to depths which are regulated 

 by the distance from the outcrop. 



North of James river. 



I have memoranda as to the following works • 

 Brown's, above 300 feet deep ; Wigham's, Ran- 

 dolph's, Woodward's, Tuckaho, Deep Run pits, and 

 others. 



Willis's : shaft about 130 feet ; raising 600 or 700 

 bushels per day, by mules. Not troubled with water. 



Crouch's : engine shaft 230 feet, used only for draw- 

 ing off water. 



There are twelve old shafts in this vicinity ranging 

 parallel with the crop, within one mile. Three only are 

 now worked. 



Graham's or Anderson's : canal pit 270 feet ; deep 

 shaft 450 feet. Several other shafts adjoining, and 

 working both seams ; numerous old workings from the 

 crop. 



These mines are troubled with water, on account of 

 the unnecessary number of old shafts, which, by perfo- 

 rating the strata, convey the surface and drainage water 

 into the workings, from whence it is raised by mule 

 power. 



South of James River. 



River pit 130 feet, abandoned for the present ; Pow- 

 hatan pit, Norwood pits and others, on the west side of 

 the basin. 



On the east side are Tribue's, Salley's, Black Heath, 

 Cunliffe's, Blunt's, Heath's shafts; Maidenhead, 400 

 feet; Creek, 280 feet ; Union; Bell, 400 feet ; Rise, 400 

 feet ; Mills's deep shaft, 412 feet ; Mid-Lothian, 500 

 feet, and the workings, it is understood, are carried to 

 the depth of 700 feet; Stonehenge, 400 feet; Hill, 480
