98 POLE STEAM-ENGINE. 



Mr. Phillip was the financial managing shareholder 

 more particularly with the Londoners at that resus- 

 citation of Herland Mine ; and though the new engine 

 was comparatively cheap, both in its first cost and in 

 its consumption of coal, and satisfactorily reduced the 

 water in the mine, payment for it was withheld because 

 the currents of self-interest were against Trevithick. 

 Mr. Joseph Price was the manager of a steam-engine 

 manufactory at Neath Abbey, in South "Wales, and had 

 been in the habit of supplying castings for Cornish 

 mines. Arthur Woolf was then striving to bring into 

 use his patent double-cylinder engine, and patent high- 

 pressure steam-boiler, which Trevithick looked on as 

 copies from Hornblower and himself. This, added to 

 Woolf 's sarcastic manner of speech, roused Trevithick's 

 anger. 



Putting aside the words of the disputants, the fact is 

 stated that the pole-engine, with a reduced steam pres- 

 sure, worked a pump 14^ inches in diameter, 10-feet 

 stroke, fourteen strokes per minute ; while the largest 

 and -best engine by Watt in Cornwall, placed on the 

 same mine, with a 72-inch steam-cylinder, gave motion 

 to a pump of 14 inches in diameter, 7-feet stroke, at 

 twelve strokes a minute ; being in round numbers just 

 one-half the amount of the work performed by Trevi- 

 thick's comparatively small engine, which had not a 

 single feature of the Watt engine in it.
