VIII AUTHOR S INTRODUCTION 



and Cattle department, introduced illustrated Charts giving the formation 

 of the teeth at the various ages, accompanied by such explanation and in- 

 struction as will enable any one, by a little s'udy and observation, to ascer- 

 tain with almost perfect accuracy the ages of tlicco animals at any period. 

 The great value of this knowledge is readily seen and cannot well be over- 

 estimated. "With this information, and the ability to understand special 

 characteristics and defects, instruction in which .: ~"?ip given and illus- 

 trated in such careful detail, the arts of the joc!::^/ '.vi.. jz oltectually pro- 

 vided against. 



The subject of training has received elaborate consideration, and as the 

 value of an animal depends greatly on the care and success with which it 

 has been trained, it is believed that the atl ition given to it will be pro- 

 ductive of valuable results. 



In this, as in other departments, gentle and humane methods are advo- 

 cated as the most satisfactory as well as the most profitable. Allied to this, 

 the directions and facts given concerning proper shelter, convenience and 

 economy in building, are deemed of interest and value. 



In the attainment of clearness, the generous and prodigal liberality of 

 the Publishers in illustrating, by accurate, well executed and striking en- 

 gravings, every department and chapter of the work, desen^es special 

 attention. As aiding and strengthening the enforcement of fact, this 

 feature, made at enormous outlay, is of a practical value impossible to 

 exaggerate. 



In conclusion, the hope is indulged that the farmer and stock raiser who 

 will attentively read these pages, and reduce to practice the suggestions 

 here given, will find such increase of success, profit and pleasure in his 

 noble calling as to justify his good opinion and the endorsement of this 

 volume. If so, the author's purpose in writing it will have been accom- 

 plished.
