The other arm was the one by means of which the stones were hoisted. When a stone had to be raised; its weight was ascertained, and the movable weight was so fixed as exactly to counterbalance it. By this simple contrivance all the cumbrous and troublesome machinery of long guys and bracing-chains extending from the crane to the rock below were avoided.
The external part of the beacon was now finished, with its supports and bracing-chains, and whatever else was considered necessary for its stability in so far as the season would permit; and although much was still wanting to complete this fabric, yet it was in such a state that it could be left without much fear of the consequences of a storm.
At last the beacon was so far advanced and secured that it was deemed capable of withstanding any gale that might blow. As yet it was a great ungainly pile of logs, iron stanchions, and bracing-chains, without anything that could afford shelter to man from winds or waves, but with a platform laid from its cross-beams at a considerable height above high-water mark.
Upon narrowly examining the great iron stanchions with which the beams were fixed to the rock, the writer had the satisfaction of finding that there was not the least appearance of working or shifting at any of the joints or places of connection; and, excepting the loosening of the bracing-chains, everything was found in the same entire state in which it had been left in the month of October.
There was not the slightest indication of working or shifting in the great iron stanchions with which the beams were fixed, nor of any of the joints or places of connexion; and, excepting some of the bracing-chains which had been loosened, everything was found in the same entire state in which it had been left the previous season.

Each beam was to be fixed to the solid rock by two strong and massive bats, or stanchions, of iron. These bats, for the fixing of the principal and diagonal beams and bracing-chains, required fifty-four holes, each measuring a foot and a half deep, and two inches wide.
