Show Scalei In the Mint. Passing through the mint attention waB directed to a large pair of scales, which wero sold to be as fine as anything any-thing In the country. They recalled the grand balance Bcalo used In the Dank of England, and on Inquiry tho mint scales proved to be a worthy specimen of tho samo class. Tho Old Lady of Thrcadneedlo street uses a piece of mechanism that stands about seven feet high and wolghs In tho neighborhood of two tons. This scalo is sot every da, Just as the one at tho mint Is, and Is so delicately ad-Justed ad-Justed that It will correctly weigh a grain of dust or 400 pounds of gold. A postago stamp would affect tho index in-dex six Inches.. If any weight beyond be-yond its capacity Is placed on the machine ma-chine It makes Its protest by ringing an electric bell and keeping It up until Us load Is lightened. Philadelphia Record. |
