Letters wiere received yesterday from Pernambuco, dated the 19th of Augast. Lord Cochrane, with the Imparial squadron from Rio de Janeiro, arrsived off Pernambuco on the 17th, to commence thei-M&ade ofVthe airlour, ari landed 1,000 troops at a place about six leagues to the southward. He thien sent in a communication to the fo- 1eign consuls, announcing, that in the event of a,protracted resistance, he had orders to destroy the harbour of Per- iambuco by sinking slhips laden with stones at its entrance, and requesting them to make this known to the different comnmanders of vessels in the port, that eaclh might pursue what course he thought proper. The situation of affairs within the town of Pernambuco was extremely aiarming to the foreigna merchants, and to those peaceful residents whliO took no share in the coutest between the Impe- rial and Republican party. Carvallio, the head of the latter, subsequently to the defeat of his forces in the inte- rior, had taken possession of the forts with the remainder of his troops, the strength of which secured him against any attack which could be made from the land side; and being a man of desperate courage, was expected to make a protracted resistance in the event of any attack from the Bay on the part of the blockading squadron. The whole of the interior of the province had risen in arms against the t*overnor, and were marehing against k'ernambuco. The ad- vices from the interior of Pernambuco do not come dowffi&A later date than the 19th, but it has been ascertained by a vessel which passed the port on the 31st, that Lord Coch. rane wvas at that time bombarding the town, and that he was warping his vessels,for the purpose of entering the bay, in order to approach nearer to the battcries. It is infcrred, therefore, that up to this period his Lordsbip had not carried into effect his threat of destroying the harbour, a circumstance whichl, by prevenling access to the town, would effectually prove the ruini of Pernambuco. Consi- derable uneasiness is felt by the merchants here connected with Pernamnbuco, for the safety of their correspondents and property within the place, from 3vhich they had no possibility of personal escape, even if disposed to abandon tle property committed to their cars, and wliici remained exposed to all the diestructive effects of the bombardmenit. , DRAZIL.
