Hautsch adapted to his engine a flexible pip*which could be turned to any side ; hut certainly not an air-chamber, as Schottwould have mentioned it. In the time of Belidor there were no other engine*in France, and the same kind alone were used in England in 1760. At h astthat conclusion is induced by the account given by Ferguson, who calledNewshauvs engine, which threw the water out in a continual stream, a newinvention. In Germany the oldest engines were of that kind. Who first conceived the idea of applying to the fire-engine an air cham-. FIRE ENGINE.

According to a conjecture of Perrault, Vitruvius seems to speak of a simi-lar construction. But the obscure passage in question might be explained inanother way. There can be found no older fire-engine constructed with anair-chamber than that of which Perrault has given a figure and says it was kept in the kings library at Paris, and during fires could pro-ject water to a great height; that it had only one cylinder and yet threw outthe water in one continued jet. He mentions neither its age nor the inventor;and it can only be added that Perraults book was printed in 1684.
