The situation of Boto Fogo impresses every one who visits it, most agreeably--it is a delightful retreat from the hot and unwholesome air of the city and is, like the Praya Flamingo and the Gloria hill, the residence of many respectable foreigners. The little bay, fronting the pretty sandy beach, seems like a tranquil lake embossed in magnificent mountain-scenery. Having replenished our partially-exhausted stock of sea-stores, and the commodore being with the squadron at La Plata, we were compelled, reluctantly, to proceed to that place and set sail accordingly, on the twentieth of May. The situation of our squadron at La Plata, arose out of difficulties which existed between the Argentine Republic and that of the United States, consequent upon the unlawful and unfriendly capture of American vessels, sealing among the Falkland islands, by order of Vernet, the governor; and from the proper and spirited conduct of Captain Duncan, commander of the Lexington, in removing the colony to Montevideo, and thereby, most effectually cutting off all further depredations upon our commerce. [Sidenote: MONTEVIDEO.] We received the customary assistance of boats, from the various men of war, in towing the ship out of the harbour. As we passed the British line-of-battle ship Plantagenet, the band of musicians struck up our national air of “Hail Columbia.” On the thirtieth, we made St. Marys, being the northern cape at the entrance of the river. A brisk breeze the day following, accompanied with misty weather, wafted us, at midnight, within four miles of the isle of Flores, on which we found an excellent revolving light--and the weather clearing up, we saw the dull light which crowned the hill called Montevideo. Sail was then shortened to maintain our position until daylight; but in the course of three hours, a strong current running out of the river, had forced us into four and a half fathoms of water, on the edge of the English bank. We anchored, on the second of June, in the roadstead of Montevideo, near the United States’ ship Lexington. On the next morning, we again sailed, with a strong easterly gale, for Buenos Ayres, and at noon anchored in three and a half fathoms of water, off Pinta de India, in thick weather and a bad sea. In the afternoon, it became sufficiently clear for us to obtain a glimpse of the tops of some trees; sail was again made and on the fifth, we came too, in the outer Balissas, near to the United States’ ship Warren, under the command of Acting-Commodore Cooper, and the schooner Enterprise, commanded by Lieutenant-Commodore Downing. Having landed Mr. Baylies and family, and taken in provisions for our voyage across the South Atlantic and Indian oceans, we sailed on the nineteenth, and in four days arrived at Montevideo. As we passed to our anchorage ground, H. B. M. frigate Druid, A. R. Hamilton, commander, complimented our flag by her musicians playing “Hail Columbia,” which cheered our hearts and
