On Threshing out Wheat by a Roller. 39 



the most accurate account which I have read of it, war- 

 rants the conclusion here made. 



OBJECTIONS TO TREADING. 



1. The wheat must be stacked out of doors. This does 

 uot necessarily follow. If the barn stands on the edge of 

 the yard, the bands of the wheat may be cut, and the 

 wheat thrown into the yard, almost as expeditiously, as 

 off the stack, however, it will consume more time on 

 the whole, and therefore stacking round the yard should 

 be preferred. A stack, well put up, will stand 18 

 months without leaking a drop of water. The wheat 

 will be as sound, and the straw as good, as when first 

 stacked. This I know from experience, although it was 

 improper to suffer it to remain so long. 



2. Again, the stack is liable to injury from fowls. 

 This may be obviated by a close rail- fence round the 

 yard ; and by securing the top with briars, brush, or timo- 

 thy hay, or hay of any long grass which will lay close. 



If the stack is elevated by a few blocks, or large stones, 

 and strong fence-rails, so as to raise it a foot or 18 inches 

 from the ground, to admit dogs and cats occasionally to 

 go under it, rats will not do half the injury as if the 

 wheat is put directly on the ground, or on rails laying 

 on the ground. 



3. It has been said that threshing with the Scotch ma- 

 chine " more generally separates the grain from the 

 " straw, than possibly can be accomplished by treading. " 

 This I do not believe when the roller is used ; though 

 I never saw the Scotch machine, and probably the wri-
