Haystack Building.

centre of the stack is filled up. As the centre is approached, put tlie 

 sheaves closer together, so as to make the middle of the stack tighter and 

 higher than the outside ; always lap each succeeding row at least as far as 

 the band on that preceding. From then on, as each fresh layer of sheaves 

 is applied, keep the centre well trampled and slightly higher than the 

 outside sheaves, and the butts of the sheaves in each row to the outside of 

 the stack. 



Many builders commence from the centre, especially on small stacks 

 where no stage is used, and the practice is a good one, though the one

recommended will be found even better where a stage is built. Both styles 

 of building are similar after the first two layers have been laid ; everv fresh 

 layer of sheaves should be commenced from the out.side of the stack, always 

 working to the centre and keeping the surface even with an elevation to the 

 centre to give a pitch for any water that might penetrate the roof of the 

 stack. If this is done and the middle well tramped, the stack should be 

 safe from rain. 



FIG. 3. SYSTEM OF BEGINNING LAYERS AFTER FIRST TWO ARE PLACED. 



The sheaf turner should always stand, as nearly as possible, in the 

 centre of the stack, and should not trample on the outside row under any 

 circumstances, as he will displace or push out the sheaves and spoil the 

 shape of the stack. Each layer of sheaves should be put on in the 

 same way as the first, except that, after the second layer is put down, the 

 butts should be kept to the outside in the rows. The loose or ungainly 

 sheaves should be used to keep up the middle. The very outside row 

 of sheaves in each layer should not be as tightlv packed as those tow^ards 

 the centre. This will admit of the outside settling as the stack pro- 

 gresses, and give a fall to the exterior which will allow the water to run
