gland, and the adrenal-sympathetic system to increase to a 

 remarkable size. Were these race horses subjected to a 

 chase by a pack of hounds or wolves, the thoroughbred, 

 with its ability for high speed, might, in its effort to escape, 

 so increase its internal temperature that it would be over- 

 come by heatstroke. 



No animal such as the zebra or the oryx possesses 

 so highly developed an energy-controlling system as the 

 thoroughbred horse. In this connection it is to be borne in 

 mind that the horse is the only animal save man that sweats 

 all over. Sweating facilitates the elimination of internal 

 heat and in consequence permits the development of a 

 larger brain, larger heart, larger thyroid gland, larger 

 adrenal glands, and larger celiac ganglia and plexuses, with 

 diminished danger of heatstroke. 



The endowments of the Arabian horse that make him a 

 gentle companion of man, requiring a small amount of food, 

 capable of enduring long-distance travel but not equipped 

 for as high a speed of outburst energy as the thoroughbred, 

 are expressed in a brain and adrenal glands smaller than 

 the thoroughbred's. The balanced energy system of the 

 Arabian horse is comparable to the balanced energy system 

 of Oriental man. Thus it is this unique energy formula, 

 possessed only by the Arabian horse, that endows it with 

 its unequaled endurance, coupled with high intelligence 

 and gentleness. . 



Pattern of the Draft or Work Horse 



The draft horse does not require outbursts of energy, as 

 would the cavalry horse or the running horse. The draft 

 horse requires a mechanism adapted to the long, continuous 

 carrying of a pack and the long, continuous pulling of a 

 load. The kind of energy man wished to transfer from him- 

 self to a member of the horse family was that of carrying a 

 load, including the load of man himself. The draft horse 

 does not need outbursts of energy. Therefore, the draft
