How Grain will Shrink. 



Farmers rarely gain by holding on to their grain after it is fit for market, 

 when the shrinkage is taken into account. Wheat, from the time it is threshed, 

 will shrink two quarts to the bushel or six per cent, in six months, in the nvst 

 favorable circumstances. Hence, it follows that ninety-four cents a bushel 

 for wheat when first threshed in August, is as good, taking into account the 

 shrinkage alone, as one dollar in the following February. 



Corn shrinks much more from the time it is first husked. One hundred 

 bushels of ears, as they come from the field in November, will be reduced 

 to not far from eighty. So that forty cents a bushel for corn in the ear, as it 

 comes from the field, is as good as fifty in March, shrinkage only being taken 

 into account. 



In the case of potatoes taking those that rot and are otherwise lost 

 together with the shrinkage, there is but little doubt that between October and 

 June, the loss to the owner who holds them is not less than thirty-three per cent. 



This estimate is taken on the basis of interest at 7 per cent., and takes no 

 account of loss by vermin. 



One hundred pounds of Indian meal is equal to 76 pounds of wheat, 83 

 of oats, 90 of rye, in of barley, 333 of corn stalks.
