CHAPTER II. 



THE SENSORIAL FUNCTION. 



Be.\utiful as is tlie horse, and identified so much with our pleasure and our profit, 

 he has been the object of almost universal regard ; and there are few persons who do 

 not pretend to be somewhat competent judges of his form, qualities, and worth. From 

 the nobleman, with his numerous and valuable stud, to the meanest helper in the 

 stable, there is scarcely a man who would not be offended if he were thought alto- 

 gether ignorant of horse-flesh. There is no subject on which he is so positive ; there 

 is no subject on which, generally speaking, he is so deficient ; and there are few 

 horses, on some points of which these pretended and self-sufficient judges would not 

 give a totally opposite opinion. 



The truth is, that this supposed knowledge is rarely founded on principle, or the 

 result of the slightest acquaintance with the actual structure of the animal — the form 

 and connexion of parts on which strength, or fleetness, or stoutness, must necessarily 

 depend. 



In speaking of the structure of this animal, and the points which guide the opinion 

 of real judges of him, we shall, as briefly and as simply as we are able, explain those 

 fundamental principles on which his usefulness and beauty must depend. We require 

 one kind of horse for slow and heavy draught, and another for lighter and quicker 

 work ; one as a pleasant and safe roadster — another, with more speed and equal con- 

 tinuance, as a hunter — and another still is wanted for the race-course. What is the 

 peculiarity of structure — what are the particular points that will fit each for his proper 

 business, and, to u certain degree, unfit him for everything else 1 The fiirrner will 

 require a horse of all-work, that can carry him to market and take him round his farm 

 — on which he can occasionally ride for pleasure, and which he must sometimes 

 degrade to the dung-cart or the harrow. What combination of powers will enable 

 the animal to discharge most of these duties well, and all of them to a certain extent 

 profitably !
