ABSTRACT
I T has already been stated that Boulton & Watt had little prospect of supplying many of their engines to collieries where coals were cheap and where the saving of fuel was of little importance. The first engines, however, were all pumping units, and it was necessary, therefore, to find mines other than coal mines as a market for them. Further, it was imperative that this market should be fairly extensive and stable in order that the firm could proceed with the building up of their business on a sound basis.
