Plate from the 'Illustrated London News'. The introduction of the pump and hose in the late seventeenth century had represented a significant advance in firefighting, but the drawback was that the pump had to be worked by a team of men. This was solved in the 1860's by the introduction of the steam pump. In addition, steam replaced horses as the means of drawing the engines.
