The fly-wheel shaft is made sufficiently long to admit of a drum being fixed on 

 if required, which can be supplied (to any diameter ordered) along with the 

 Engine, at an extra cost according to size. 



The above Engines occupy a very small space, and will be found admissible 

 in places where no other form of engine and boiler could be fixed. They are con- 

 structed in an exceedingly substantial and simple manner, every part being 

 perfectly easy of access, and consequently can be readily understood and managed. 



The boilers are fitted up with strong welded tubes (varying in number 

 according to the size of the boiler), intersecting the fire-box, and a mud hole is 

 placed opposite each tube, for the purpose of cleaning them out. They are tested 

 up to 200 Ibs. pressure to the square inch. 



The foundation plate answers the purpose of feed water tank, in which the 

 water is heated before passing into the boiler ; and also of an ashpit. 



No brickwork or foundation is required. 



N. and Z. will forward special quotations to Foreign Correspondents for Steam 

 and Gas Engines or other Machinery upon receiving details of the nature and amount 

 of work to be performed.
