heir places, single them, and continue to unlay and lay-in until
the six meeting places of the strands are equi-distant.

To finish off the ends properly can only be learnt by observation and
actual practice. By using two marline-spikes, the hempen heart is
removed and the ends of the wire strands forced into the place it
occupied, making a very neat job when finished.

Wire splices should be parcelled with oily canvas and served with
Hambro' line.
