at a manhole, one screwed to that, both are pushed forward, another one
added and pushed forward, and so on until they extend the entire length
of the duct. Then the wire is attached and the rods are pulled out and
detached one at a time and with the last rod the wire is through. At
least No. 14 galvanized iron or steel wire should be used, for any
smaller size cannot be used a second time, as a rule. In starting to
pull in the draw rope a wire brush should be attached to the wire and to
this again the rope, and when the brush arrives at the distant end of
the duct it very likely will bring with it a miscellaneous collection of
material which for the good of the cable had better be in the manhole
than in the duct.

The reel or drum carrying the cable should be mounted on wheels or jacks
and placed on the same side of the manhole as the duct into which the
cable is to be drawn, and must always be so placed that the cable will
run off the top of the reel.

There are several methods of attaching the draw rope to the cable. As
simple and strong a method as any is to punch two of these holes through
the cable, lead and all, and attach the rope by means of an iron
wire--some of the draw wire will do--run through these holes. Depending
on the length and weight of cable to be pulled it can be drawn either by
hand or by a multiplying winch. The rope should run through a block
fastened in the manhole in such a position that the rope shall have a
good straightaway lead from the mouth of the duct.

The strain on the cable should be perfectly uniform and steady; if the
power is applied by a series of jerks either the lead covering may be
pulled apart or some of the conductors broken. At the reel there must
always be a large enough number of men to turn it and keep the cable
