The gas passes from the purifiers to the station meter house fronting the stores on the north side of the yard, where the quantity of gas made is registered; adjoining which is Mr. Methven's the Sub-Manager's office, and a test room or laboratory where various experiments connected with the manufacture of gas are conducted. Against the north boundary is a small gas house with gas-holder, etc., all complete, occasionally used for experimenting purposes. From the station meters the gas passes to the gas-holders; each of these enormous circular vessels possesses great storage capacity. It is made on the principle that the circle of all geometrical figures is the one that a fixed circumference or outline is capable of enclosing the greatest amount of space. A gas-holder is made by riveting together light wrought iron sheets upon an angle framing and in shape resembles an inverted cup, the crown being either flat or the segment of a large sphere. It works in a circular water-tank, round which columns are erected that sustain guides at proper intervals by which the gasholder when working is supported, etc. Erected in different parts of the works, including those (two) in the field Prince of Wales' Road, are five immense gasholders with double lifts capable of holding in all 7,000,000 cubic feet of gas. The most imposing view of the Works is from the gate near the entrance of the Creek at Mill-Pond Bridge; in the creek there are sometimes as many as forty barges. On entering at this gate the eye is attracted by two ponderous lifts, which, by an arrangement of rope bands attached to shafting with revolving iron drums and pulleys supported by columns and girders and driven by two horizontal engines of twelve horse-power, are capable of lifting 500 tons of coals every twelve hours. The coals are raised from the barges in iron waggons which hold 1 ton 15 cwt. each, there are two waggons to each lift so that while one waggon is being filled the other on the stage above is being conveyed on iron rails to whatever part of the retort house the coals may be required. Each engine has a powerful brake and is worked with two levers. On the west side of the creek is the manager's residence, and an enormous gasholder with capacity to hold 2,000,000 cubic feet of gas; further on is a hand crane. In front of No. 7 retort house is one of Winshurst and Hollick's engine cranes, which is capable of lifting 200 tons of coals in ten hours by means of a chain and bucket lifted up to the hopper, a distance of nearly sixty feet, and emptied. The bucket holds 15 cwt. of coal. That portion of the Company's premises known as Mill-Pond Yard is used for the storage of pipes, bricks, fire-clay, etc. Here is the carcass of the Old Tidal Mill with lock gates; here too is the Workman's Institute and Band room. Mothers' Meetings are held at the Institute on Wednesdays at 3 p.m., on Sunday afternoons at 3 o'clock for Bible readings by a Missionary in the district.[1]
