24 B Canadian Arctic Expedition, 1913-18 



Insert the left thumb into the middle of the figure above the lower trans- 

 verse string and, dropping the left httle finger loop, sharply draw the strings 

 tight. "The dog" has broken its trace, "the sled" is left danghng on the left, 

 and "the dog," dragging its broken trace, is speeding away to the right.

Make "the little old man" (No. XIII). 



On the left you have a quadrilateral, one side running from the upper 

 transverse string to pass through a loop in the middle before continuing to the 

 lower transverse string. 



Remove the thumb loops to the indices. 



With the back of the right thumb from the proximal side take up the string 

 of the triangle that runs between the radial and the ulnar little finger strings. 

 At the same time, with the back of the left thumb from the proximal side take up 

 the string of the quadrilateral that runs from the upper transverse string to the 

 middle. 



With the right thumb from the distal side remove the left thumb loop, 

 then, drawing the original right thumb loop out from under it, transfer it to the 

 left thumb from the proximal side. Invert the right thumb loop counter-clock- 

 wise so as to make it straight. 



With each thumb from the proximal side take up the radial index string of 

 its hand, navaho the thumbs and drop the index loops, taking care not to draw 

 the strings too taut. 



Transfer the thumb loops to the indices. 



In the middle two strings cross one another on the proximal side of all the 

 other strings; the one comes from the radial right little finger string, and sub- 

 sequently passes round the lower transverse string, the other from the left ulnar 

 index string and does the same.
