seen in use for this purpose. Its simplicity and the facility with 

 which the tubs are lifted for transit are its chief recommendations ; 

 no taking to pieces or removal of the side-beams, prior to loading, 

 is necessary, beyond the removal of the hind axle, which consists 

 of a strong wrought-iron bar with a hook at each end, the hooks 

 fitting into eyes fixed on the inside of the stock 

 of the hind wheels. They are made fast with a 

 pin through each hook ; when this bar is removed the machine 

 is backed to the tub, one of the hind wheels passing it on each 

 side until the tub is midway between the fore and hind wheels 



where the lifting ap- 

 paratus is fixed. This 

 being done the axle- 

 bar is fixed and the 

 machine is ready for 

 loading. 



" The stirrups 

 attached to the lower 

 end of the upright 

 lifting-rods are now 

 lowered to the bottom 

 of the tub by means of 

 the rack and pinion 

 machinery until the two iron bars, which are previously pushed 

 under the tub, can be placed in the four stirrups ; this being 

 done, all is ready for lifting the tub in an upright position by 

 the rack and 

 pinions, which are 

 worked by a man 

 on each side. When 

 the tub is high 

 enough for travel- 

 ling it is secured 

 by means of a pin 

 through the four 

 upright lifting-rods inserted at 5 in the illustration ; the tub 

 being lowered on to the pins for travelling. The whole operation 

 does not occupy the three men required to work it more than two 

 or three minutes. The machine is drawn by one horse, and it will
