The riggers carried the rope through West Princes Street Gardens to the top of the Mound. When the riggers reached the top of the Mound the cable began to unwind from the drum which had been set up in the watchtower. The cable which weighed 4 cwt. consisted of seven wires manufactured from the finest steel encased in gutta percha half an inch in circumference.
Poles were set up support the cable along the route. image credit ‘Old and New Edinburgh’ by James Grant.
