Building the Ohiong Stack. — In laying- out your stack, say, for 

 10,000 bundles, mark off four corners, 8 by 4 yards. Then place a 

 row of sheaves on end down the centre, starting- and ending- about 

 1 yard from the end; then place with the ears resting- about just 

 above the bands a row on either side and at the ends. This operation 

 is continued until you have completed the foundation of your stack, 

 which would then in the centre be the length of a sheaf high, sloping 

 down to the thickness of a sheaf on the side and end. You 

 then start your first layer from any point on the boundary of the 

 stack ; push the stubble end or butt firmly in behind the band, holding 

 the sheaf at the same angle as the slope or pitch of your stack, 

 continuing until a row (see section of stack. Fig. I, A) on the outside 

 of the stack is completed. The second and subsequent rows running 

 close up to the centre of the stack are placed with the ear ends over- 

 lapping the previous row in order to enable the slope of the stack 

 to be maintained to allow for binding. At about a distance of two- 

 thirds of the length of a sheaf from the centre of stack, place one row 

 on either side of the centre with the stubble ends against the previous 

 row (Fig. I, B), so that the heads just overlap one another. The last 

 row is then placed to cover the overlapping heads, with the stubble 

 ends alternately to one side and the other (see Fig. I, C). Once your

stack has got a good slope, the inner rows can be placed on sub- 

 sequent layers of sheaves with stubble ends together, and heads over- 

 lapping one another, but as soon as tiie stack begins to lose its pitch 

 heads must be placed overlapping the stubble of the previous rows as 

 in first layer, Fig. I. This will immediately raise the stack in the 

 centre. 



The corners of a four-sided stack should be slightly rounded, and 

 to obtain a desirable shape it is necessary to start drawing- the heads 

 of the sheaves slightly away from the corner, commencing four or 

 five sheaves away, to make room for the corner sheaf (see Fig. II). 

 The heads of the sheaves will overlap one another slightly. Care 

 should, however, be taken in putting down the sheaves of the inner 

 rows at the corners, so that these do not overlap too far (Fig. II, B), 

 as otherwise the stack will become too steep at the corners. In this 

 way the symmetry of the stack will be maintained. 



By placing the stubble ends behind the bands of the outer row 

 of each layer, the stack is gradually being drawn inwards, growing 

 narrower as the stack g-rows higher. When the width of the stack
