At this date one of the most remarkable of the precursors of Watt in the
construction of the steam-engine, comes in an interesting manner into
connection with Scotland. Captain Thomas Savery, an Englishman,
‘treasurer to the commissioners of sick and wounded,’ had, in 1696,
described an engine framed by himself, and which is believed to have
been original and unsuggested, ‘in which water is raised not only by the
expansive force of steam, but also by its condensation, the water being
raised by the pressure of the atmosphere into receivers, from which it
is forced to a greater height by the expansive force of the steam.’[286]
He had obtained a patent for this engine in 1698, to last for
thirty-five years.
We have seen that there were busy-brained men in Scotland, constantly
trying to devise new things; and even now, Mr James Gregory, Professor
of Mathematics in the Edinburgh University—a member of a family in which
talent has been inherent for two centuries—was endeavouring to bring
into use ‘a machine invented by him for raising of water in a continued
pipe merely by lifting, without any suction or forcing, which are the
only ways formerly practised, and liable to a great many
inconveniences.’ By this new machine, according to the inventor, ‘water
might be raised to any height, in a greater quantity, and in less space
of time,’ than by any other means employing the same force. It was
useful for ‘coal-pits or mines under ground.’ On his petition,
[Sidenote: 1701.] Mr Gregory obtained an exclusive right to make and use
this machine for thirty-one years.
Another such inventive genius was Mr James Smith of Whitehill, who for
several years made himself notable by his plans for introducing supplies
of water into burghs. Smith had caught at Savery’s idea, and made a
paction with him for the use of his engine in Scotland, and now he
applied to the Estates for ‘encouragement.’ He says that, since his
bargain with Captain Savery, he ‘has made additions to the engine to
considerable advantage, so that, in the short space of an hour, there
may be raised thereby no less than the quantity of twenty tuns of water
to the height of fourteen fathoms.’ Any member of the honourable house
was welcome to see it at work, and satisfy himself of its efficiency;
whence we may infer that an example of it had come down to Edinburgh. In
compliance with his petition, Smith was invested with the exclusive
power of making the engine and dealing with parties for its use during
the remainder of the English patent.[287]
Savery’s steam-engine, however, was a seed sown upon an infertile soil,
and after this date, we in Scotland at least hear of it no more.
