"Base Ball is a field game played principally in the United States. It originated in the English school-boy game of "rounders;" but it has been so improved and so generally played as to merit its name of "the National game of America." The plaing of baseball has become largely a business or a "profession," and skilled players receive large salaries. As an amateur game, however, it is also most popular."—(Charles Leonard-Stuart, 1911)

"Another important diamond is the one at the point of the scepter of the Russian empire, known as the Orloff, which weighs 194 and three quarters carats. At one time it formed the eye of an idol in the temple of Seringham in Mysore, whence it was stolen. It was in the throne of Nadir Shah, and after his murder it was bought by an Armenian merchant in 1772 at the price of 450,000 silver rubles and the title of nobility. By the gift of Prince Orloff, a favorite of Catherine II., from whom it derived its name, it came into her possession. Some writers believe that this and the Koh-i-Nur are the two parts of the 'Great Mogul' diamond."&mdash;(Charles Leonard-Stuart, 1911)

"Most of the great diamonds distinguished for beauty and size have very interesting histories. one of the most famous is the Koh-i-Nur, or Koohinoor, 'Mountain of Light.' The legend is that it was carried by the hero Karna, whose deeds are celebrated in the 'Mahabharata.' It made its first appearance in history in the 14th century, when Ala-ed-din brought it to Delhi. At that time it was supposed to weigh 793 carats."&mdash;(Charles Leonard-Stuart, 1911)

"In the arrangement of the flattening and annealing ovens numerous improvements have been effected, which have resulted in greatly increased smoothness and uniformity of the glass, and in considerable economy of time and labor in the operations. This shows a section of a flattening (L) and annealing kiln (M) in common use. The split cylinder O is introduced and gradually pushed forward so as to be uniformly heated till it reaches P, the flattening stone or table, mounted on a movable waggon N. On this waggon after it has been flattened it is carried into the annealing arch M, as shown by the dotted outline. Here in a less heat is graually stiffens, till it is ready to be moved by a forked tool to a horizontal position on the bed of the annealing oven." &mdash; Encyclopedia Britannica, 1893
