A man with a wrench opens the nozzles in succession, each stream cleaning to a line ahead 

 of the next nozzle until the operator has gone over the entire area between hydrants 



Flushing Streets with Streams from The Northern Logger Is the Nerviest 

 Movable Pipe-Lines of Our Steeplejacks 



DIFFKRING entirely from all pre- /^NE has only to go to the <lcpths of

 r.itus, a simple de\ice recently put on and meet the logger in his native haunts 

 the market con- 

 sists of a jointed 

 line of piping with 

 valves at regular 

 internals, thewhnle 

 being placed in the 

 center of the street 

 from hydrant to 

 h\(lrant and thi'

 plished by turning 

 on each nozzle in

 pipe line is made 

 up of sixteen-foot 

 sections, each 

 mounted on two

The lumberman calmly smokes his pipe as he 

 oils the blocks at the top of the swaymg pole 



to recognize in him 

 all the qualities 

 which go to make 

 up a nervy stccplc- 

 ( limber. He thinks 

 nothing of doing 

 an ordinary 

 >teeplejack's job 

 before breakfast 

 and then dogging 

 f.dling trees and 

 setting off dyna- 

 mite blasts until 

 the supper bell 

 rings. 



The accompany- 

 ing photograph 

 shows a logger in 

 the act of oiling 

 two large blocks. 

 He was hoisted to 

 his dizzy position

 gine, and as he sat 

 there, straddling 

 two thin steel 

 cables, he was so 

 much at home that 

 he smoked his pipe. 

 The large pole is a 

 gin-pole, erected to 

 lift the logs.
