June 21, 1918. THE COLLIERY GUARDIAN. [supplement PAGE XV.] 1279 Coal Saving For Collieries. Our Special Proposition. We are prepared to make a complete scientific investigation of the working of any Colliery boiler-plant and to design a scheme of reorganisation to obtain the maximum saving possible, which in average cases will vary from 20—40 [ of the coal bill. We will then carry out the reorganisa- tion and supply the machinery, plant, and appliances that may be required, together with all brickwork and foun- dations, and lend the services of one of our skilled engineers to work the reorganised plant under our super- vision until the results are obtained. We will carry out the whole of this work entirely at our own expense, and are willing to be paid only by a pro- portion of the savings for a fixed period. At the end of this period the reorganised plant will become the pro- perty of the Colliery irrespective of the savings, and no financial responsibility whatever will be incurred except by ourselves. We shall be glad to explain our proposition personally or by letter, and are prepared to visit your Colliery free of charge and give you our opinion of the working of your boiler-plant. ftomviilw & s'lUtn £td„ TECHNICAL CHEMISTS & ENGINEERS, SPECIALISTS IN FUEL ECONOMY. 2, AUSTIN FRIARS, LONDON, E.C. 2.
