The habitation, for so plantations are here called, which was to be my residence, belonged to a respectable widow with a large family; and was represented to be five French leagues, or twelve miles from the town, in a S. S. W. direction.  The permission to range two leagues all round I considered to be an approach towards liberality; and a proof that, if general De Caen had ever really believed me to be a spy, he had ceased to think so; it was not indeed consistent with the reason alleged for my imprisonment, to grant a parole at all, but this it was no part of my business to point out.  On the other hand, by signing this parole I cut myself off from the possibility of an escape; but it seemed incredible, after the various letters written and representations made both in England and France, that a favourable order should not arrive in six or eight months.  I moreover entertained some hopes of Mauritius being attacked, for it was not to be imagined that either the East-India company or the government should quietly submit to such losses as it caused to British commerce; and if attacked with judgment, it appeared to me that a moderate force would carry it; upon this subject, however, an absolute silence was preserved in my letters, for although the passport had been so violated by general De Caen, I was determined to adhere to it strictly.

During four days stay in the to town of Port Louis no restriction of any kind was imposed; I visited the theatre, and several families to whom my friends Pitot and Bergeret introduced me, and passed the time as pleasantly as any one who spoke no French could do in such a situation.  A young Englishman, who under the name of an American expected to sail immediately for Europe, took charge of a box containing letters and papers for the Admiralty and president of the Royal Society, one of which was upon the effect produced on the marine barometer by sea and land winds;* and on the 24th in the afternoon I set off with M. Pitot’s family for their country house, which was four miles on the way to my intended residence.

[AT MAURITIUS.  WILHEMS PLAINS.]

On the following day we visited the country seat of the governor, called the Reduit, about seven miles from the town, and at the edge of my limit of two leagues from the habitation at Wilhems Plains.  It stands upon an elevated point of land between the Riviere de Mocha, which comes from the east, and an equally large stream which collects the waters of Wilhems Plains from the southward; their junction at this place forms the Grande Riviere, and the Reduit commands a view of its windings in the low land to the north, until it is discharged into the sea about a mile on the west side of Port Louis.  There was little water in the two rivers at this time; but the extraordinary depth of their channels, which seemed to be not less than a hundred feet, and to have been
