LTD GA TESHEAD-ON-TYNE Cheap Steam. The most promising field for Coal Saving in Collieries to-day is the boiler house, that is, the production of steam at the cheapest possible rate. In order to get cheap steam it is first necessary to find out what the steam is costing at present, and most collieries are working their boiler plants in the dark in this respect. We have had ten years experience as Specialists in the business of cheap steam production, and we are prepared to make a thorough scientific investiga- tion of the working of your boiler plant and to undertake a reorganisation to bring it up to date. We are further prepared, if necessary, to carry out the work entirely at our own expense, and be paid out of the savings. 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. ihwnlie & (Or cm Ltd..
