Mr Miller on the Original Inventors of Steam Navigation. 87 



In both figures the nozles and twere are seen. The cavity at th» 

 end of the twere is for the burning charcoal. 



A is a peg driven into the ground between the two nozles. The 

 nozles are bound together by a thong, and the upper part of 

 the peg, which is hooked, holds down thjs thong, so that the 

 nozles are kept firmly in their place. The top of the peg is 

 seen between the two nozles in the upper figure. 



B is a mud-wall, which serves to screen the bellows from the heat 

 of the fire. 



Memoir regarding Symington and BelVs pretensions to he con- 

 sidered the original Inventors of Steam Navigation ; being 

 an Appendix to a Narrative on the Introduction and Practice 

 of Steam Navigation^ ^c. published in the Philosophical 

 Journal for July 1825. By P. Miller, Esq. 



XjLaving, in justice to the memory of my father, the late Mr 

 Miller of Dalswinton, given a short account of his claim to the 

 adaptation of steam to navigation, which appeared in the Edin- 

 burgh Philosophical Journal in July 18S5, I now find myself, 

 in consequence of the continued and unwarrantable pretensions 

 of others, reluctantly compelled to obtrude again on the public 

 attention, in order to set these pretensions at rest. 



In my former statement I have proved, that, on the recommen- 

 dation of Mr Taylor, the tutor in my father's family, from whose 

 advice alone my father at any time received the smallest assist- 

 tance on this important subject, he sent for William Symington, 

 then employed at Wanlockhead mines, in spring 1788, to su- 

 perintend the construction of a small steam-engine to be used in 

 the experiments he was then carrying on at Dalswinton, for pro- 

 pelling vessels with wheels. In October following, the engine 

 and machinery were completed, and put on board a pleasure- 

 boat on the lake at Dalswinton, and completely answered the 

 expectations of my father, and many other persons who had op- 

 portunities of seeing the experiments. 



So much was this the case, that, in 1789, my father resolved 

 to extend his experiments ; and, in June that year, sent Sy- 

 mington to Carron, with a letter to the Manager of the Carron 

 Company, in order to get a steam-engine constructed for a dou-
