Sir, — 1 BEG yon will do me the honour to inform the

 or stays, DD, to support the weight of the front part, and 

 prevent its falling any lower until other means can be re-

 shafts detached and lying on the ground ; the connection

 which is seen at b, passing through the bed of the cart, and 

 also through the iron hinges a a, by which the shafts are 

 united to the cart: besides these screw-bolts two steady 

 pins, or bolts without heads, also pass through holes in the 

 shank of each of the hinges, ard two nuts BB are screwed
