20 inches by Hi inches by | inch thick, and be made of 

 ordinary deal wood ; the cross pieces should be 11| inches by 

 2 inches by | inch, and of the same wood as the boards. 



The grain of the wood of the boards, and of the cross 

 pieces, should run longways ; the grain of the cross pieces, 

 when attached, runs across the grain of the boards. 



These cross pieces should be attached to the boards, two 

 on each, placed 2f inches from the end of the boards ; 

 they should be fixed to the board by means of long malleable 

 iron nails, fully 2 inches in length, with large flat heads of 

 fully half an inch; the length of the nail when bent, and 

 the flat broad heads, give a good solid grip of the wood, 

 without causing splitting. The two outer nails should not 

 be driven into the wood further from the end of the cross 

 piece than 1 inch. 



There should be two plain pieces of board, 20 inches by 

 11| inches by | inch, with four loose cross pieces Hi inches

One piece of waterproof sheeting 36 inches wide, 

 10 feet long; this is intended for covering 

 two packages of paper, but it is best to keep 

 it as an entire piece, and only divide it when 

 required for use with two parcels. The

Equally as good waterproof sheeting for the 

 purpose can be got in England, weighing half 

 the amount ; this w^ould allow more weight 

 for paper.
