| Remarks | Sunk on Jordan Farm [36],[58]. Shaft filled with water; connects with the Chauncey Andrews mine |
| (OGS 9) [5]. Same mine as Harroff slope? The Harroff shaft is not shown on the Harroff slope |
| mine map (Mg-45); not sure what the relationship is between the two mines, whether they are |
| connected in some way. Coal identified by elevation. |
