We had scarcely entered on this important preliminary, when it was disagreeably and painfully interrupted by the firing of a gun on board the Explorer. The roar of a twelve-pounder, which jarred the building, struck a panic through the whole circle, and the volume of smoke which floated on the water alarmed them much. With my pocket spyglass I observed that the signal for a fleet in the offing was flying, and it was to call my attention to this signal that Albicore had fired the gun. It was no easy matter to pacify the internals, and make them understand that the terrific noise, fire and smoke, were quite harmless. After many useless efforts, I made them comprehend that it was but the voice of the vessel, telling me it was time to return on board. My spyglass attracted their notice. I gave it to one of the internals, and directed it to the ship, showing him how to find the focus. An exclamation of surprise showed me that this discovery in optics was unknown to them. This little incident was of great service to me. It showed the internals that some useful knowledge might be obtained from the hideous strangers, and excited their curiosity to know more about us. I now made signs to the two persons appointed to instruct me in the language, to accompany me on board, which after a few minutes they did, together with two others, ordered for the same purpose, and to make observations on our vessel and manners. I was the more willing to render this interview a short one, because I saw that no progress could be made until we had arranged some mode of communicating our ideas. Soon after our arrival on board, a boat came off from the shore with a large supply of fruits and milk, which were most joyfully received; and in return, I sent a spyglass, a looking-glass, and several articles of glass ware. The vessels which had been signalled by Albicore, entered the bay and passed into the river, without coming any nearer to us than the land compelled them to.--After having shown my visiters about my ship, every part of which they examined with scrutinizing attention, I conducted them to my cabin, and sat down to the study of their language. Two devoted themselves to this object; the other two wrote an account of all they had observed, and sent it by the boat which brought the fruits and milk.
