Account of the Erection the Bell Rock Lighthou'se. 23 
moving the stones from the lighters anchored off the rock, to the 
wharfs and cranes formed upon the rock. They were doubly for- 
tified by a water-tight ceiling or lining, in case of damage by being 
grounded upon the rock, and were farther prepared for the worst 
by a number of empty casks, which were stowed under deck, and 
were of themselves capable of keeping the praams afloat. There 
were also several attending-boats for transporting the artificers 
from the tender to the rock ; and one of these was fitted up as 
a life-boat upon Greathead^s principle. The moorings of the 
various cr^ft consisted of chains, with cast-iron mushroom an- 
chors, admirably adapted to the situation. Tracks of iron-rail- 
ways were laid, upon one level, along the rough and uneven sur- 
face of the rock, on which the great blocks of stone were wheeled 
upon waggons, also constructed chiefly of cast-iron. The little 
wharfs were provided with cranes adapted to the peculiarities 
of the respective situations. A descriptive account is given in 
the volume of the various cranes, sling-cart, stone-jack, winch- 
machine, and Lewis-bat for quarrying purposes, of the moulds 
for stone-cutters, pumps, and other machinery, in a detailed 
manner which must be highly interesting and useful to the, en- 
gineer and the architect. 
While engaged in this undertaking, notwithstanding all its diffi- 
culties, the artificers seem to have spent their time in a very hap- 
py and cheerful manner, and to have been well satisfied with their 
rations of provisions, pay, and premiums. At first the whole time 
of flood-tide was a period of leisure. On these occasions, in good 
weather, some were seen busy at their books, others were musi- 
cally inclined, and many found amusement in fishing. The only 
evil they seem to have complained of was sea-sickness, for which 
even time itself hardly proved a cure, owing to the excessive 
rolling of the ships. They, therefore, strained every nerve to 
fit up a barrack upon the beams of the beacon, which was at 
once to relieve them from the constant liability to sickness, and 
from the danger and perplexity of the movements, both by 
night and day, in boats to and from the rock. The force of 
habit, however, under such perilous circumstances is finely ex- 
emplified in the testimony borne by Mr Stevenson to the readi- 
ness with which men, little versant in sea affairs, were brought 
to embark with alacrity, and to work with the tool in one hand.
