ENGLISH COAL, AND HUMAN POWER.— Professor Rogers estimates that nearly one-sixth of the total annual produce of our coal mines is used for the production of mechanical power alone, from which a power equal to that of 66,000,000 able-bodiee men 'is obtained Each acre of a seam yielding 3 feet of pure fuel is equal to about 5,000 tons, and possesses a reserve of mechanical strength equal to tbo the labour of 1,600 men during their whole life; and each square mile of the same bed contains 8,000,000 tons of fuel, which is equal to 1,000,000 men labouring through 20 years of their ripe strength. Upon the same calculation, the total annual coal production of the United Kingdom (65,000,000 tone) is equal to the strength of 400,000,000 strong men, or more than double the number of adult males now upon the globe. LONE' AND MURDRIt.—Tho Court of Aseizes of Indre, a few days back, condemned to death a man, named Plantureux, for the wilful murder of a young woman, who had refused to receive his addresses. The most remarkable fact connected with the ease was, that Plantureux, in the year 1856, when a soldier in the Imperial Guard, was tried by Court-martial for attemptto murder a young woman at Courbevoie, under similar circumstances, and was condemned to a' imprisonment and military degradation. After undergoing his punishment, he went to Malicorney (Indre), and in April last entered the services of a farmer. He there became smitten with a servant girl living in the same house, but she would not listen to him, and she r on leaving her place to avoid his importuthe day she left- he. isiet the-girl and be the rosa, end offered to beti to carry *lilt luggage. lie walked with them a mile or two, and when they were about to separate, he murdered the poor girl in the presence of her mother by repeated stabs with a knife, and then took to flight. He was, however, soon arrested. The jury brought in a verdict of Guilty," without mentioning extenuating eircum' stances, and the Court accordingly passed sentence of death.
