8 INTRODUCTORY 



their business, and know about how far their conditions 

 warrant the extension of their operations, so that it is not so 

 necessary to offer suggestions to them along this line. It is 

 true that the breeder of market hogs always has a use for pure 

 blood, but it is not every person who can make a success of 

 breeding pure-breds to supply the demand for breeding stock, 

 and the average farmer is safer to adhere to producing market 

 hogs. 



To sum up, it may be said that the hog is especially valu- 

 able for consuming the by-products of the farm, and the 

 number of hogs carried to advantage upon a farm is governed 

 very largely by the quantity and character of the by-products 

 to be consumed. When carried in appropriate numbers, the 

 hog is an exceptionally economical producer of meat, preventing 

 waste, and giving cash returns for substances that are fre- 

 quently wasted, or which have little market value. Trying to 

 take advantage of fluctuating market prices by alternately over- 

 stocking and under-stocking with hogs is seldom a financial 

 success. The man who consistently follows up the business 

 upon conservative lines is the man who is well satisfied with 

 the hog as a source of profit.
