[B & w photograph, in 2 parts, of ms. letter] 1828 Jul 25, Liverpool [to] Timothy [Hackworth] / Geo. Stephenson. [He asks if Hackworth is 'going to lay off the Locomotive Engines' for 'it was a great pity that these accidents took place with the tubes'. He says Brandreth has got my plan introduced for the horses to ride which I suppose he will set off as his own invention' [a reference to the Cycloped?]. Stephenson meant to try the system at Canterbury but 'that Company have determined to work the Line by steam power'. He reports on 'the new Locomotive Engine at Bolton which works beautifully' [i.e. the Lancashire Witch] and to the bellows draught used on it for burning coke. In a postscript he adds that John Dixon and all the Canterbury directors 'can speak to my plan of carrying the Horses', a system he felt inappropriate at Darlington. On SM neg. 455/89]
