HISTORY OF MAURITIUS. 
to shorten the passage from-the Isles of France and Bourbon to India, they are similar 
to my own, and I shall hereafter give them a particular consideration. 
“ M. du Roslan, seconded by the Chevalier D’Herce, continued the progress of 
discovery after the Chevalier Grenier, and has fulfilled that object with equal care 
and correctness. His observations and remarks will be explained hereafter. I shall 
therefore pass at once to the discoveries successively made in this Archipelago. 
“ The Isle de Sublets ituate to the north of the Isle of Bourbon, in the latitude 
of i5°52', was discovered by the vessel called the Diana, in 1722. The store- 
ship the Utile was wrecked there the 31st of July, 1761, from having neglected to 
refer to its situation as laid down in my chart of 1753, and having preferred another 
chart, which places it 25' more to the south. This island is a flat bank of sand, 
of about seven hundred fathom in length, running north-north-west and south-south- 
east, and of three hundred and fifty in breadth, with a ridge of sand stretching six 
hundred fathom to the south-south-east. The crew saved themselves in a kind of 
flat-bottomed boat, made out of the wreck, and landed at Foule Point on the 27th 
of September. 
“ The bank of Corgados Garayos was, in 1742, the first object of the researches 
made by the boat named the Charles, and the tartan the Elizabeth, dispatched from 
the Isle of France by order of M. Mahe de la Bourdonnais, at that time Governor 
of it. These two vessels having made it on the 27th of August, anchored there, and 
traced a plan of it, by which it is represented in the form of an horse-shoe, and of 
six leagues in extent, running north-north-east and south-west. These two boats 
not having been on the north side, and, consequently, not having perceived the isles 
which lay off it, its small extent, and the affinity of its latitude and longitude with 
that of Saint Brandon, on which an English vessel, called the Hawk, (le Faucon) 
was stranded on her return from Surat to Europe, induced me to consider it as 
one and the same shoal. 
“ It was perceived in 1682, by the ship La Royale, in its passage from Surat to 
the Isle of Bourbon ; and her course, till she came in sight of the Isle of France, 
then called Mauritius, was south-west by south, 4 0 west. 
“ From the tracks of the two boats, I was induced to give it 58° 7' of longitude: 
nevertheless, as the course of M. le Chevalier Grenier is more direct, having taken 
a mean proportion between his own course, and that of the La Royale and the two 
boats, I have replaced it in 57 0 37', that is 30' more to the west.
