MANUAL OF PACK TRANSPORTATION. 143 



Should the corona be wet, leave the canvas side exposed to dry; in 

 due time fold coronas, cover, and tie down. (See sec. 74.) 



HOW TO FOLD PACK COVEKS. 



Sec. 77. The operation of folding a pack cover is similar to that 

 provided for the folding of a pack blanket, with this exception, that 

 the pack cover is square. (Sec. 18.) 



HOW TO FOLD RIGGING COVERS. 



Sec. 78. For this purpose two packers are ordinarily employed; 

 each packer takes hold of one end at corners, folds and brings the 

 corners together, and holds corners with one hand; the packer at 

 one end holds the corners with the right hand, while packer at oppo- 

 site end holds corners with the left hand. 



Now, with the free hand, each packer takes hold of the folded 

 corner, and bracing from each other they draw taut on cover, to cause 

 the folds to lay evenly. Then one packer lays his end on the ground, 

 while his mate gives a quick swing backward, so as to cause the oppo- 

 site end to come quickly toward him, and places end on top of oppo- 

 site end. 



Now fold one end, and fold opposite end on top of fold thus formed 

 so as to have folds of equal length; or each end may be brought 

 together and folded as may be determined. 



HOW TO FOLD CARGO COVERS. 



Sec. 79. For this purpose two packers are employed; each packer 

 takes hold of one corner on the same side of cover and folds within 

 the last section or strip; now fold this odd section or strip on top of 

 fold already formed, then fold once more and draw taut. Now fold 

 one end to near center of its length, and fold opposite end on top of 

 fold thus formed, or as conditions may require. 



HOW TO FOLD FEED COVERS. 



Sec 80. The operation of folding feed covers is entirely similar to 

 that prescribed for rigging covers. 



In preparation for the day's march, pack, rigging, cargo, and feed 

 covers so folded are placed lengthwise m front of rigging selected. 



In the operation all canvas should be well shaken in order that dust 

 and other matter may fall therefrom. In no case must folded covers, 

 when placed on the aparejo, reach within six inches of the boots or 

 ends of the aparejo, or must the folds be wider than the width of the 

 aparejo.
