MOUNTED INSTRUCTION 201 



Midshipman's Hitch is a variation of the l^lackvvall Hitch. AfU-r 

 having' made the IMackwall hitch another iiitch is made around the 

 onter ])art of the hook. It is I)etter adaj^ted than the lUackwah Iiitch 

 hecause it does not sHp or become nndone as readily as the latter. 



The Wall Knot and the Crown on Wall are both nsed for finishing 

 olT ends of ropes to prevent unstranding. 



Splices, (Page 181, Engineers' Field Manual) 



1. Eye Splice, 



2. Long Splice, 



3. Short Splice. 



Slings. 



1. Horizontal Barrel Sling, 



2. Vertical Barrel Sling, 



3. Ordinary Sling, 



4. Body Sling. 



The ordinary sling is nothing more than a large bowline made into 

 a sling around a box, barrel or package. 



If the loops of a bowline on a bight are made large these loops may 

 be used as a body sling, one loop passing under the arm pits, the other 

 loop under the knees. 



Lashings, (Page 182, Engineers' Field Manual) 



1. Shear Lashing. 



2. Gin Lashing, 



3. Square Lashing, 



4. Hold Fasts. 



Blocks and Tackles. (See ])age 185 Engiiwers Field Manual.) 

 The follow^ing are the princi])le points to be carefully observed in the 

 arrangement and the use of tackles. 



(a) That the condition and strength of the straps. l)locks and fall 

 are good. 



(b) That the fall is free from kinks and runs freely over the sheave. 



(c) That the lead and running end of the fall do not rub against 

 the shell. 



(d) That the running end goes in the proj^er direction, otherwise 

 both the fall and the shell will suffer. 



(e) That the blocks are well lubricated, and both blocks and fall are 

 at all times kept free from dirt and grit. Blocks not in good working 

 order will "com])lain," that is, make a noise or scuieak. 



(f) Tackles should be carried and not dragged along the ground. 



(g) See that the pins securing the hook and the sleeves of the blocks 

 are not loose, that the standing end of the fall is properly fastened to 

 the block. 



(h) See that the fall is properly stoppered and that the stopper is 

 fully equal to the strain to which it will be subjected. 



(i) The position of the men should be such as to insure safety to 

 themselves in case of accident.
