But it was not until 1702 that, according to some accounts, the first steam pumping-engine was erected in Cornwall, by Savery.

Friend Savery "will gladly put him in the way of obtaining money by means more likely to bring him peace of mind."

But Savery persisted until, at Isaac's request, the commander of the Ganges kept the paymaster quiet by stratagem.

Savery's patent (the first granted for a steam engine), is dated 1698.
