40^ 



has become about 10 feet or when it is getting too high, the head 

 should be put on. All the above measurements would vary according 

 to the length and thickness of the sheaves. 



The construction of the head is similar to the rest of the stack, 

 excepting that the centre sheaves are laid lengthways along the 

 centre line of the stack and not across it (Fig. Ill, A). 



Corners of Stack. 



The ears of the rows of the sheaves from either side of the stack 

 will soon begin to overlap (Fig. Ill, B). As soon as a row overlaps 

 the previous one by about a foot, the stack is completed (see Fig. 

 Ill, C). 



Sometimes it is preferable putting the last two rows with the 

 ears hanging downwards, but this is not essential. 



Cross Section of Cap of Stack. 



It is not advisable having more hands on the stack than is 

 absolutely necessary; on a large stack four men, and on a small one 

 two are enough. 



In finishing off, it is advisable to fasten the cap down by pinning 

 the sheaves with wooden pegs not more than \ inch thick ; this also 

 applies to a four-sided stack, when the end bundles of the top layer 

 may be pinned down, and in addition the bundles joined together 

 by taking a small handful of straw from each bundle, and pushing 

 this under the band of the adjoining bundle.
