however may not be relished by those who are impatient to be rich, and value a little money more than the lives of their fellow-creatures. It often happens, however, where they are driving home an Adit upon the course of the Lode, that the water, as they come near the old workings, zighyrs away by flow degrees, through the Adit end, if it is tender and porous; and inftead of holeing to the house of water, they very happily hole to Learys, or the old Gunnies, or excavated parts of the Mine. The new Adit being holed in to the old workings, they immediately prepare to draw out the water; and when the bottoms are forked, or quite unwatered, they proceed to clear them of all flime, fludge, and attal, that may have fallen into them fince the Mine was knocked or fet idle. Afterwards they fink, ftope, and drive in various parts of the Mine, according to the best of their judgment, and in the manner before described. The reader will conceive, that almost every Mine, from variety of circumstances and natural contingencies, will require a different management, and method of working; and that one certain mode for working two different Mines is impracticable. We have only to remark, that no Mine can be well wrought without using the forementioned general methods, however varied they may be in the manner and application. A General Display of a Mine, by Notes of Reference to and an Explanation of every Part of a whole Sheet Parallel-Section of Bullen-Garden Copper Mine; wherein is exhibited all the Machinery, and Workings, from Grafs to the Sumph, shewing every Pump, Saller, Ladder, Drift, Stope, End, Winds, and Stull, in the Mine. 1,2 The western water engine tyes, or pumps, which deliver the water to adit. 3 The ciftern into which the water runs, from the old fire engine rose pumps 17. 4 5 A fmall bore, or fmall pump.
