The release of Sanguily has aroused some very bitter feeling in Havana, and the Spaniards are saying that Spain ought not to submit to it, nor to General Lee's conduct in regard to the murder of Ruiz. These murmurs are so loud and threatening, that all the Americans who can do so are leaving the island with all possible speed. Should the Spanish attack them, they have no means of defence; the Consulate is an unprotected building, and Consul Lee has no men at his disposal to protect them. Gomez appears to be advancing toward Havana. From the last reports a large body of insurgents was seen at Cienfuegos. They mustered about 5,000 men, and were supposed to be commanded by General Gomez himself. The news was brought by bands of Spanish soldiers who had fled at his approach. They said the army was marching in long lines, two foot-soldiers abreast, with the cavalry covering them on the two sides, one horseman behind the other. Cienfuegos is about two hundred miles from Arroyo Blanco, where Gomez won his great fight. To reach this place he has crossed the great Eastern Trocha, and is now but a hundred and fifty miles from Havana. It is reported that General Weyler came back to Havana suddenly and unexpectedly, and it may have been in consequence of the approach of Gomez. * * * * * The filibusters are busy again. Word was sent to the Treasury Department the other day, that a large steamer, supposed to be carrying arms and men to Cuba, had left Barnegat, on the Jersey Coast. It was reported that this steamer was the _Laurada_, the famous filibuster, about which we spoke in Numbers 6 and 9 of THE GREAT ROUND WORLD. The _Laurada_ came back from her Spanish trip, and appeared to be conducting herself like a good, peaceable steamer; but, if reports are true, she has suddenly commenced her tricks again. She took on coal and provisions at Baltimore, pretending she was going to Philadelphia, but she has not yet been heard of at that port. A steamer answering to her description has appeared off Barnegat, taken on quantities of arms and ammunition, and about a hundred men, among whom it is supposed was General Carlos Roloff, the insurgent Minister of War. The little revenue cutter _Manhattan_ was ordered out of New York Harbor, to arrest her; and loaded with arms, and with four United States Deputy Marshals, she hurried off in chase of the naughty steamer. She made all haste to Barnegat, having to make her way through heavy seas that tried the nerves and the stomachs of the passengers. When she arrived, there was no _Laurada_ in sight; that saucy vessel had made the most of her opportunities, and was a hundred and fifty miles down the coast. The marshals got nothing for their trouble but a chilly trip and a bad attack of sea-sickness. It seems that the secret of the expedition was ferreted out by some Pinkerton detectives, who are in the employ of the Spanish.
