goodie, near Dundee, for supplying sandstone for the interior. 
The principal establishment ashore was fixed at Arbroath, 
where a large inclosure was procured for the preparation of the 
stones, connected with barracks for the accommodation of the 
artificers. On the 7th of August 1807, Mr Stevenson, accom- 
panied by Mr Peter Logan, his principal assistant, and a few 
artificers, went off to the Bell Rock, fixed upon the site of the 
lighthouse, and commenced the works by cutting away a thick 
coating of large sea-weed ( Fucus digitatus and esculentus and 
tracing the foundation of the lighthouse with pick-axes upon the 
rock. On this occasion, it was stipulated, that those workmen 
who went to the rock, should remain one month without going 
ashore ; while the workmen in their turn stated their terms at 
^Os. per week, summer and winter, wet and dry, with free 
quarters and victuals when at the rock : — As for Sunday’s work 
and premiums, we leave that to the honour of our employers.” 
In the first stage of the works, two or three hours’ labour up- 
on the rock was considered a good tide’s work ; at the conclu- 
sicMi of which, the artificers, carrying with them all their tools 
and implements, had to betake themselves to their boats, and to 
proceed, often under many disadvantages, to the tender, which was 
moored in the offing. The erection of some temporary refuge 
on the rock, in case of accident to the boats, formed part of Mr 
Stevenson’s original design, and he accordingly lost no time in 
setting about the construction of a wooden beacon-house. This 
indispensable accompaniment to the works was successfully com- 
pleted in the latter end of September, and, as the author expresses 
it, robbed the rock of much of its terrors, and gave a facility 
to the works which could not otherwise have been attained.” 
The want of such an accommodation at the building of the Edy- 
stone Lighthouse, where the smallness of the superficial dimen- 
sions of the rock did not admit of such an erection, formed one of 
Mr Smeaton’s chief difficulties. The Edystone does not lie nearly 
so low in the water as the Bell Rock, and consequently the cubical 
contents of the building projected by Mr Stevenson were nearly 
double those of Mr Smeaton’s lighthouse. The erection of this 
temporary beacon-house forms perhaps one of the most interest- 
ing parts of the undertaking. The principal beams, which were
