4. THE ENDURANCE OF THE PACK MULE UNDER PROPER 

 CONDITIONS. 



Sec. 86. As a prerequisite he must not be less than 14.1 and not 

 over 15.1 hands high, of blocky build, weighing frona 950 to 1,100 

 pounds, sound in body and Umbs, age from 4 to 6. 



Head well formed and intelligent looking, broad between the eyes, 

 eyes clear, large, and full; ears flexible; teeth and tongue free from 

 blemishes; neck full and inclined to arch; withers low and broad; 

 back short and straight; belly large and deep; dock low and stiff; 

 legs straight, standing well apart at front and rear, the former indi- 

 cating good lung power, the latter full in buttocks; the hoofs sound, 

 broad, and full. 



The mule should have a pack saddle that will protect the body 

 from all manner of loading — that is, capable of being adjusted so as 

 to support heavy loading when necessary without injury to the 

 withers and with a proper bearing surface on either side of the ani- 

 mal's backbone. For such a purpose there is no form of pack saddle 

 that has ever been devised comparable to the aparejo. 



As an instance of the adaptability of the aparejo to carry heavy 

 and unwieldly loading, reference to figure 110 will show what can be 

 accomplished by the aid of the aparejo and expert packer. This cage 

 mount of naval rapid-fire gun, weighing 540 pounds, was taken from 

 the gunboat Quiros (Captain Walker, U. S. Navy) and carried 3 

 miles inland, island of Jolo, P. I., and back again on the same multf 

 by order of Col. H. L. Scott. 



To accomplish this feat Assistant Chief Packer Mora E. Smith 

 made a wooden frame to fit over the aparejo as a base on which to 

 rest the cage and lashed the frame to the aparejo. The cage was 

 then lifted onto the mule and secured with lash rope. Such a feat 

 could not be accomplished by the use of the crosstree or Moore pack 

 saddle.
