'_Inventor and constructor of the first high-pressure steam-engine, and the first steam-carriage used in England_; constructor of a tunnel beneath the Thames, which he completed to within 100 feet of the proposed terminus, and was then compelled to abandon the undertaking; inventor and constructor of steam-engines and machinery for the mines of Peru (capable of being transported in mountainous districts), by which he succeeded in restoring the Peruvian mines to prosperity; also of coining-machinery for the Peruvian mint, and of furnaces for purifying silver ore by fusion; also inventor of other improvements in steam-engines, impelling-carriages, hydraulic engines, propelling and towing vessels, discharging and towing ships' cargoes, floating-docks, construction of vessels, iron buoys, steam-boilers, cooking, obtaining fresh water, heating apartments, etc.' The following is a list of his patents: NOS. DATES. PATENTS. 2599 (1802) Steam Engines for Propelling Carriages. 3148 (1808) Ship Propeller. 3172 (1808) Iron Tanks for Ships. 3231 (1809) Iron Docks, Ships, Masts and Spars, Buoys, Steam-arm, etc. 3922 (1815) Screw-propeller.[151] 6082 (1831) Surface Condenser. 6083 (1831) Heating Apparatus for Rooms. 6308 (1832) Superheating Steam. But this list by no means exhausts the whole of his inventions, for he was so fond of talking of them before they were matured that many were found sharp enough to seize Trevithick's ideas, and then to reduce them into some practical and remunerative form for themselves. Sorry reward this for such incessant industry and varied inventive skill as induced Hyde Clarke to write as follows: 'In the establishment of the locomotive, in the development of the powers of the Cornish engines, and in increasing the capabilities of the marine engine, there can be no doubt that Trevithick's exertions have given a far wider range to the dominion of the steam-engine than even the great and masterly improvements of James Watt effected in his day.'
