142 MANUAL OF PACK TEANSPORTATION. 



the ground may require, the length of the holes being perpendicular 

 to the direction of the picket line. 



For each "dead man" take a sling rope, tie its ends together, and 

 give a single twist on rope and bring the loop ends together; this 

 causes the folds to lie evenly. Twist again and bring the loop ends 

 together as before. 



Now hold the folds of rope in the left hand at opposite point, or 

 part where ends of rope had been tied; at opposite part grasp the 

 folds wuth the right hand and bring the folds to the middle finger of 

 the left hand and receive them. 



Now introduce the "dead man" through the folds of rope made by 

 this formation, and allow the folds of rope held in the palm of the 

 left hand to fall over the folds of rope held by the middle finger, and 

 draw taut on "dead man," and tlie "dead man" is thus caught in a 

 shpknot. As in the case, as seen in fig. 82. 



Place the "dead man" in the hole dug for it, and keeping the end 

 of the sling rope out, fill the hole and tamp. 



The picket line is then stretched by being attachetl to these sling 

 ropes. 



As facilitating the tightening of the rope, the following is a con- 

 venient method of stretching the picket line: 



If the picket line consists of a single rope, fasten one end to the 

 sling rope of one of the " dead men;" bring the other end through the 

 loop at the center "dead man." About 10 or 15 feet from this end 

 form a bowline knot on the rope; then pass the end through the loop 

 of the sling rope at the last "dead man;" bring it back and pass it 

 through the loop of the bowline. 



By drawing on the end all slack is now readily taken in, and the 

 end is then secured. 



If the picket line consists of two ropes, fasten each to one of the 

 extreme " dead men;" take an end of one, pass it through the loop at 

 center "dead man," and form a bowhne knot in the end. Then pass 

 the free end of the other rope through the loop of this bowline, draw 

 taut, and secure as before. 



Obviously the same method may be employed when the ends of the 

 picket line are attached to other forms of holdfasts than the one here 

 considered. 



HOW TO CLEAN CORONAS. 



Sec. 76. For this purpose a table knife is ordinarily employed, and 

 for convenience a provision is supplied on selected aparejo. This is 

 done by cutting a slit between tlie two inside lines of stitching on the 

 "near" side of "front" facing, just wide enough to permit the blade 

 of knife to pass downwardly; the handle of knife will hokl it in posi- 

 tion. Two or more knives may thus be provided for cleaning pur- 

 poses. 



Immediately after the aparejos have been taken off the packmaster 

 or cargador details certain packers to assist in cleaning coronas. 



Commencing at each end, spread corona, canvas side up, and allow 

 it to fall on either side of aparejo, and with knife clean the canvas 

 thoroughly. Before cleaning corona place corona on top of aparejo 

 adjoining, and clean the canvas and dock of crupper thoroughly; then 

 replace corona and proceed and clean, as explained.
