England.----Sir FRANCIS KNOWLES has recently taken out a patent for producing iron in an improved form. In blast-furnaces, as at present constructed, the ore, the flux, and combustibles, are mixed together; and the liberated gases of the fuel injure the quality of the iron, and cause great waste, in the shape of slag. By the new process the ore is to be kept separate from the sulphureous fuel in a compartment contrived for the purpose, in the centre of the furnace, where it will be in contact with peat only; and in this way the waste will be avoided, and a quality of metal will be produced fully equal to the best Swedish. The invention is likely to be one of considerable importance.----Professor JOHNSTON, the distinguished English agriculturist, who visited this country last year, and lectured in several of the principal cities, at a late farmers' meeting in Berwickshire, gave a general account of the state of agriculture in America, as it fell under his personal observation. He represented it in the Northern States as about what it was in Scotland eighty or ninety years ago. The land in all New England he said had been exhausted by bad farming, and even in the Western States the tendency of things was to the same result. He thought it would not be long before America would be utterly unable to export wheat to England in any large quantity. * * * * * Affairs in FRANCE are still unsettled. The Government goes steadily forward in the enactment of laws restraining the Press, forbidding free discussion among the people, diminishing popular rights and preparing the way, by all the means in their power, for another revolution. The most explicit provisions of the Constitution have been set aside and the government of the Republic is really more despotic than was that of Louis Philippe at any time during his reign. A warm debate occurred in the Assembly on the bill for restricting the liberty of the press. It commenced on the 8th of July and gave occasion to a violent scene. M. Rouher, the Minister of Justice, spoke of the Revolution of February as a "disastrous catastrophe," which elicited loud demands from the opposition that he should be called to order. The President refused to call him to order and M. Girardin threatened to resign saying, that he would not sit in an assembly where such language was permitted. He did not resign, however, but his friends contented themselves with handing in a protest the next day which the President refused to receive. The debate then proceeded and an amendment was passed, 313 to 281, declaring that all leading articles in journals should be signed by the writers. On the 15th an amendment was adopted that papers publishing a _feuilleton_ should pay an additional tax of one centime beyond the ordinary stamp duty. On the 16th the bill was finally passed by a vote of 390 to 265. * * * * *
