Anderson Mine.-—The tail rope system of haulag-e has been introduced in this mine during the year, of which the following is a general de- scription : The engines are of 100 horse power with boilers, ropes and electric signal system complete. The engines, of which the accompanying cut is an illustration, consist of two cylinders 13 inch bore by 15 inch stroke, coupled at right angles to one engine shaft svliich is geared to the drum shaft by heavy gearing. The two drums are each 5 feet in diameter by 30 inch face with flanges to hold 9,000 feet of three-fourth-inch hauling rope. Both drums are loose upon the shaft, the heads being fitted with hard bronze bushings and are connected to the drum shaft by means of heavy patent band friction clutches which are securely keyed to the drum shaft and are both operated by the one-hand wheel shown in cut. Each drum is provided with a separate brake band operated by foot levers on either side of the hand wheel for operating clutches and in convenient reach of the operator without leaving his position. By this arrangement, when one drum is driven by the engine the other runs loose upon the shaft, but is controlled by the brake, thus keeping just the required tension on the ropes. Steam for operating this plant is supplied by two steel cylinder boilers, each 40 inches in diameter by 30 feet long, which supply more than enough steam for the engines. When hauling, the trip-rider can communicate at any time with the engineer by means of the electric signal system, which reaches every part of the mine in which the ropes are placed ; this arrangement allow- ing the tri}) lider to mine. start or stop the trip at any desired point in the At present the hauling is on the main entry and one side entry, but
