Dynamite has excited the fears of people in London. Dennis Deasy, who carried a box containing explosives and infernal machines, and a railway porter named Patrick Flanagan, supposed to be his accomplice, were arrested in April in Liverpool. At Flanagan’s lodgings were found a number of explosives and a false beard, besides a revolver and other equipments for doing mischief to life and property in London. The most interesting evidence given during the examination was that of expert scientific witnesses, who testified that the explosive material in question was known as “lignine dynamite,” an article that could not by any possibility be connected with commercial or business transactions, and which was not made for any legitimate purpose. * * * * * A number of gentlemen who have recently come here from Europe, and most of them from England, have determined to buy land for grazing purposes in Virginia. It seems strange that Americans go to the far West to invest in great farms, and thus locate their herds of cattle thousands of miles from the sea coast, while in the Eastern States, near to markets at home and abroad, may be found hundreds of thousands of acres of lands good for nothing else but grazing. * * * * * The first reunion of the Christian and Sanitary Commissions was held at Chautauqua several years ago, amid a blaze of enthusiasm. This year, from July 22 to 24, they will meet at Ocean Grove, in New Jersey. The chaplains of the Federal and Confederate armies will meet with them. Mr. George H. Stuart, president, and the Rev. John O. Foster, of Waterman, Ill., secretary, issue the call. * * * * * Joseph Cook has closed his Monday lectures in Boston for the season. * * * * * The Postmaster General, Timothy O. Howe, died within the past month. This is the first death of a Cabinet officer since 1869. General Howe served as a judge, in Congress, and in the Cabinet. He was a warm friend and admirer of General Grant. He did not support civil service reform. His name was never connected with frauds or scandals during his public life. Judge Walter Q. Gresham, of Indiana, has been appointed to fill the vacancy in the Cabinet. His record as a soldier, citizen and judge has been of the best, and those who know him say that he will be one of the strongest among the President’s secretaries. * * * * *
