works. I kept them for many years, but now the greater part 

 of them have gone to light the fire ; all the drawings are gone." l 



The engines described by Mr. Pape are of the type 

 made by Trevithick, in Wales, about 1804, having a 

 fire-place in the boiler, and similar in form to the Welsh 

 locomotive. 



The drawings which served to light the fires certainly 

 included Trevithick's plans for the steam-locomotive, 

 ploughing engine, the screw-propeller, and many others 

 of equal interest. 



" DEAR SlR, " STABLEFORD, March 26th, 1870. 



"My grandfather's name was John Jasper, Esq., of 

 Stableford ; he must have been one, if not the first, user of a 

 steam-engine for thrashing, winnowing, and shaking the straw 

 all at one operation ; it may have been erected eighty years ago, 

 for an old servant of the family just now "dead, aged ninety, 

 worked when a boy in the steam-mill at Bridgenorth erected 

 by my grandfather about the same time. 



" The thrashing engine was a side-Jever engine, worked with 

 a three side-way cock and tappet, a cylinder about 8J inches 

 in diameter, and a 3 feet 4 inch stroke, cast-iron crank-shaft, 

 cross-head, and guides. The boiler was placed underneath the 

 engine, the fire under it, with brick flues. The boiler was about 

 9 feet long and 4 feet diameter. 



" The old side rods made of wood are still here, and so was 

 the engine until about twelve years ago. I sent the cylinder, 

 &c., to Coalbrookdale. 



" I am, Sir, 



" Yours truly, 



"THOMAS SMITH." 



The Stableford agricultural engine was probably 

 made in 1804. The cylinder, of 8 inches in diameter, 

 is precisely the size of that in the Welsh locomotive,
