 6 inches is a good width. Two narrow strips of wood or 

 iron should be screwed on to the back of the board, one 

 at each end, projecting about 3 inches upwards and down- 

 wards, the latter piece, in the form of a spike, being forced 

 into the soil to keep the board in position, and both of 

 them to prevent the board from toppling over while being 

 filled with plants.

Two sets of these boards should be made, each long 

 enough to do a whole line, as one can be in position whUe 

 the other is being refilled with plants. There is thus no 

 delay. One advantage of using these boards is that they 

 are easily filled by women or boys, who do the work away 

 from the lines and out of the way of the diggers. 



The following few hints in regard to digging may be 

 useful : 



Never use too big a spade or take too wide a spit of 

 ground. A man using a smaller spade or taking a smaller 

 spit will work much easier and faster than a man using 

 a larger spade, and the digging will be better. A No. 2
