out of all guy lines. Continue raising the poles by pulling
on the guys away from the butt anchorage, at the same time
giving way with the other guys. When the pole is in position,
secure the guy lines to their anchorage.

Holdfasts are used to anchor a line to the ground, as for a
(2) Directions for making.-To make a holdfast, drive
stout pickets into the ground, one behind the other, in the
line of pull. Secure the head of each picket, except the last,
by a lashing to the one behind it. Tighten the lashings by
rack sticks and then drive the points of these into the ground
to hold them in position. The distance between pickets
should be several times the height of the picket above the
b. Deadman (see fig. 55).-(1) Use.-A deadman has the
same use as a holdfast except that it has greater strength,
although it requires more labor to construct.
(2) Directions for preparing.-To prepare a deadman, lay
a log or timber in a transverse trench with an inclined trench
intersecting it at its midpoint. Pass the cable down the in-
clined trench, take several turns around the log, and fasten
the cable to the log by half hitches and marline stopping.
If the cable is to lead horizontally or incline downward, pass
it over a log at the outlet to the inclined trench. If the cable
is to lead upward, the log is not necessary, but the deadman
must be buried deeper. Stakes driven at an angle over the
log prevent it from rolling out.
* 30. BLOCKS AND TACKLES (figs. 56 and 57) .-The parts of a
block are the shell or frame, the sheave or wheel upon which
the rope runs, and the pin upon which the wheel turns in the
shell. Blocks are designated by the length of the shell in
inches and by the number of the sheaves. Those with one,
two, three, or four sheaves are called single, double, triple,
and quadruple. The smallest size of block (length in inches)
that will take a given rope is nine times the rope diameter.
Self-lubricating blocks should be used where obtainable.
