Describe the tail-rope and endless-rope systems, and say which you prefer. 7. Describe all the safety appliances and attachments you consider necessary from the windingengine to the cages, signals, &c, and state what inspections are necessary to be made of colliery machinery. Explain in detail how ropes and chains should be examined. Subject No. 7. — On Geology, Surveying, and making Plans. 1.
