PREFACE 



No branch of animal husbandry has passed through 

 so many serious changes in the last century as has

 them in the utilization of high-priced lands are to 

 be realized. The range areas devoted to sheep are 

 diminishing, and, as the industry comes to have a 

 more stable position on general farms, the supplies 

 and market prices may be expected to be more
