 the chain is all drawn out the rear man calls out " chain " 

 or " halt," and prepares to hold his end of the chain on 

 the mark. The rear man lines in the other, by the com- 

 pass ahead, by stakes left, or by the marks and bushing

along the line. Kinks are shaken out, the chain is levelled, 

 and proper tension is applied. When all is ready and the 

 rear man has his handle firmly held on the mark, he calls 

 out " stick" to the leader who sets his pin at once and 

 calls " stuck." When the rear man hears this signal, and 

 not before, he pulls his pin and both men move quickly 

 forward, repeating the operation till the head man has 

 stuck his last pin or has reached the end of the line. 

 When the head man has stuck his last pin he calls 

 " tally." The rear man then drops his end of the chain, 

 counts the pins to make sure that none has been lost, and, 

 going forward, gives them to the head man who counts 

 them again. The tally is marked down and a stake left at 

 the point for reference in case of a lost pin or other cause 

 of debate in the next tally. Pins should be set plumb, and, 

 in general surveying practice, the point held to is the point 

 at which they enter the ground. In the brush and "down 

 stuff" of some woods lines, however, it is sometimes neces-
