158 Captain Tillard's Narrative of the Eruption , &c. 
forward by our hands, we at length reached that part of it 
where it gradually widened itself and formed the summit of 
the cliff, which we found to have a perfectly flat surface, of 
the dimensions before stated. 
Judging this to be the most conspicuous situation, we here 
planted the Union, and left a bottle sealed up containing a 
small account of the origin of the island, and of our having 
landed upon it, and naming it Sabrina Island. 
Within the crater I found the complete skeleton of a guard- 
fish, the bones of which being perfectly burnt, fell to pieces 
upon attempting to take them up ; and by the account of the 
inhabitants on the coast of St. Michael's, great numbers of 
fish had been destroyed during the early part of the eruption, 
as large quantities, probably suffocated or poisoned, were occa- 
sionally found drifted into the small inlets or bays. 
The island, like other volcanic productions, is composed 
principally of porous substances, and generally burnt to com- 
plete cinders, with occasional masses of a stone, which I should 
suppose to be a mixture of iron and lime-stone ; but have sent 
you specimens to enable you to form a better judgment than 
you possibly can by any description of mine.
