An Oakland telegram in the "Alta Cali fornia " of April 16th give the particulars of an accident resulting in the total destruction of the works of the Giant Powdei Company, and the loss of twenty-five human lives. The accident was occasioned by the explosion of an immense quantity of Giant powder. Soon after the explosion at the works of the same company in this city about four months ago— a casualty that entailed an enormous loss of life—the new works at Berkeley were built and put in operation. They were situated on what is known as Seva's Knoll, a part of a peninsula that extends into the bay for about a quarter of a mile, in as secluded and out-of the-way spot aa could be selected for such em ployment. The explosion occurred in the packing-house, and the.scene can only be described by persons who saw it at a consider able distance. The cause of the explosion will for ever remain a mystery. At the time of the explosion all the men employed by the company were at work, and besides them, there were several visitors at the place, who have not since been seen. The number of men working in the packing-house is not known. All that were there were killed instantaneously. Of the house not one particle can be found. The ground is rent ana ploughed up for hundreds of yards around. An eye-witness says that just before the accident a boy drove up to the door of the house with a double team; of whioh but a single spoke of one of the wheels is left. The magafiine was thrown flat to the ground, and the glycerine and cleaning-house completely demolished. Six other small houses on the Point were almost

totally destroyed. The bank behmd the packing-house, cxmtaining as much as 500 yards of earth, was lifted as one piece and thrown for some distance into the bay. From the number of persons missing, and the small proportion, by weight, of the bodies recovered, it is presumed that the force of the explosion carried most of the fragments of flesh into the bay, from which they would, of course, not be recovered. For two miles in a north-easterly direction along the beaoh small portions of the buildings, and occa sionally pieces of human flesh, were found.
