ILN., Admiralty Agent. The United States mail steam-ship Humboldt, with the mails from Southampton and Havre, arrived out at New York on Sunday, the 23rd May; and on the same day the screw steam-ship City of Manchester, from Liverpool, with 347 passengers, arrived at Philadelphia Wharf. Her Majesty's ketch Nutley and troopship Resistance were lying in Halifax harbour. When the Canada left, the Distance was to convey the 42nd regiment to England, and was expected to sail on the 29th ult.  The contract propellers Levantine and Osprey had been appoiutcd to convey the Cambria's mails to Bermuda and Newfoundland.  The Senate had been engaged with closed doors in debating some new treaties with the Indian tribes. Mr. Hall, the senator from New Hampshire, had brought forward a motion relative to tho expenses of capturing and remanding fugitive slaves, but it was quietly defeated. With a single exception, all the candidates for the presidency declare themselves in favour of the maintenance of the Fugitive Slave Law. A letter from Washington states that President Fillmore will not enforce the strict observance of the Tehuantepec treaty by Mexico, but that, in accordance with the suggestions of President Arista, negotiations will be entered into for a right of way across the isthmus.  On the 22nd and 24th ult. the House of Representatives was outraged in the discussion of measures for the suppression of Indian hostilities in the various federal dependencies. It was agreed that arms and ammunition should be placed at the diepoul of the inhabitants of New Mexico, Oregon, Texas, and California; but some members suggested that it would be a far better plan to station a sufficient number of properly equipped dragoons in those countries, not only to keep the Indians under subjection, but also to compel the hordes of white desperadoes to obey the laws. It was also said that the Indians are not by any means the only savages who 'murder and plunder the natives. Two Mexicans were recently arrested at Browns' villa (Texas), suspected of being connected with the ruthless bands infesting that locality. They bad curiously-made bullet-proof °oats, made of cowhide and wool, and supposed to be used by them while engaged in marauding purposes. These cortsetswere composed of an inner and outer coat of hide, filled with wool, an inch and a quarter in thickness, and elaborately stitched with thongs. When worn they formed a complete panoply for the body, and were impervious to a pistol shot if not to a rifle. The Governor of Boston has disbanded the Roxburgh Light-truards for refusing to turn out as a part of the military escort to Kossuth on the day of his reception in Boston. Only 1,500 dollars were raised for Kossuth in Albany. The Dutch frigate Prince of Orange was in New York harbour, after •cruise of three years : she was to sail for Holland on the 26th.  A portion of a regularly macadamised road was discovered recently mar Fairmount, Virginia, by the washing away of a hill-side. The road is about sixteen feet wide, runs along the bank of the river, and the stone is broken to about the size used in the formation of modern roads. In the bed of the road  was found the stump of a chestnut tree, at least 150 years old, giving evidence of the existence of a population there at some former age of the world. The 71-ibune of the 25th May says : Several lumps of gold were discovered in a ravine in the village of Mineral Point (Wisconsin) on Saturday, the tat inst.' worth from 2 dole. to 4 dole. On the Monday following, half the town turned out to search for the " hidden treasure," and in a short time found a " lead," containing gold, silver, and diamonds, and before noon 200 dole. worth of these precious metals were taken from the earth.  Madam e Goldschmidt (Jenny Lind) gave her farewell concert at Castle Garden on the evening of the 24th ult. Seven thousand persons were as quietly seated as though only seven hundred. The concert was as successful as the warmest wishes of her friends could have desired, and her reception supremely triumphant.
