The method of blasting with black powder so as to avoid the discoloration and soiling of the ice, and the ability displayed by the engineers in erecting slides and in providing sufficient friction by means of curves to avoid excessive speed in the downward journey of the ice blocks, show considerable ingenuity and skill. Glacier ice, which is perfectly pure and transparent, and which has many qualities which are greatly appreciated by the consumers, commands a higher value than that of the usual kind obtained from the lakes and ponds. A singular feature in connection with the preparation of the ice for the market is that it has been found necessary to store it for some days in special warehouses, built like
our own ice-houses, those with double walls with sawdust between them, in order to remove a coating of frosted or non-transparent ice that tends to form on the surface of the block as it leaves the glacier. — Scientific American.
Lottery for Excavating Benevento. — A bill has been presented in the Chamber of Deputies providing for a $200, 000 lottery, with the proceeds of which it is proposed to carry out excavations at the site of the Roman amphitheater at Benevento, the town founded, according to tradition, by Diomedes, and possessing Trajan’s triumphal arch, which resembles the arch of Titus at Rome, and is the finest and best preserved
of all the Roman structures. The amphitheater at Benevento is lying almost intact under a number of old houses occupied by poor people. Benevento is the capital of a province of that name, and is situated thirty-four miles northeast of Naples. In the Middle Ages it was the seat of a Lombard duchy, and in 1806 it was given by Napoleon I. to Talleyrand, who took the title of Prince of Benevento. — Exchange.
