By authentic Advices from Martinico, we learn, that on the 4th of October last, Capt. Grant Gardon [Gordon], Commander of the Argus [Argo] an English frigate, lying in the Harbour of St. Pierre, sent a Boat with 22 Men on Board a French sloop in that Harbour, in search of Powder, (supposing her to be an English vessel bound to North-America.) Intelligence of this coming to the Master of the Sloop, who was on Shore, he immediately repaired on board his Vessel to know the Reason of this Conduct; the Lieutenant of the Frigate demanded his Papers, and on the Master's refusing to exhibit them, a Squabble ensued, which being discovered by the People on Shore, they went to the Assistance of the French Master, on which the Lieutenant and some under Officers and Sailors went on Shore, where they were soon surrounded by a numerous Mob, which this Insult had ccillected; mean while the People in the Boat were drove from the Shore with showers of Stones which were thrown at them, the Officers at the same Time were hooted at by Numbers of Sailors and Negroes who followed them to the Governor's, where they went to make Complaint; but the Governor ordered them immediately to Depart, or he would have them punished for their Insolence: After much Difficulty the Officers of the Frigate got into their Boat and made off. ー During the Tumult a Boat was sent on board the Frigate to know the Reason of this Conduct, and the Frigate was soon after ordered out of the Reach of their Cannon.
