them, and hung horizontal iron ssatts Each drum,

The II IN are stationed upon t1c cradles" TO uiae
the operation. The wire Is attached 10 the traveller
rope. ami the latter rs advances carries he two wires
across tie river The tops OF the towers to the
anchor piers. Tie motion Of the Traveller is thea
reversed carrying wires. from another drum.
Backward and forward the traveller" moves, weaving
stIaIds Of TIE cables.
TIE SADDLES

cables. They Wi. be in mass hut in strands

rests rollers abo'= the groove il the saddle, There
are reasons Why tho cable is made in strands and at
greater elevation and consequently greater tension,
uan it vii ultimately occupy. These arc ANY great
