The leopard <i>(Felis pardus)</i> is a carnivore closely allied to the lion and the tiger, but differing it its inferior size, and in the fact that its tawny coat is covered with dark spots, formed by an incomplete ring of black enclosing a bright central patch. In addition to this brightly-colored form, there exists also the black leopard or panther, formerly regarded as a distinct species, but now proved to be merely a variety. Leopards occur throughout India, Ceylon, and Burma, in Persia, Palestine, Syria, Arabia, and Africa; while formerly their distribution was even more extensive. They are very active animals, and differ from lions and tigers in that they habitually climb trees. The total length, including the tail, is sometimes as much as eight feet. In India, the leopard preys chiefly on dogs and on carious kinds of monkeys; but it is capable of killing a bullock or the samber deer. The litters consist of from two to four cubs, which in India are born in spring. Leopards chiefly inhabit rocky hills covered with scrub, and in the neighborhood of villages are often a dreadful scourge to herds and flocks, and sometimes become habitual man-eaters.

This illustration shows a Surveyor's, or Y-level. In use, the telescope is set perfectly horizontal and pointed back at a rod placed vertically at the starting point. The rod is graduated and after a reading has been taken of the height above the ground cut by the cross wires of the telescope, it is moved to a point forward of the instrument, which is then revolved in a horizontal plane and a reading taken of the rod in its new position. The difference in level is obtained from the difference in readings of the two points, and subsequent readings are taken by removing the level, sighting on the rod in its second position, and then repeating the operation, the readings in this case being recorded.

A boar's head is carried into a banquet hall accompanied by musicians. The boar's head festival we know today originated at Queen's College, Oxford, England. Legend has it that a scholar was studying a book of Aristotle while walking through the forest on his way to Midnight Mass. Suddenly, he was confronted by an angry wild boar. Having no other weapon, the resourceful Oxonian rammed his metal-bound philosophy book down the throat of the charging animal, whereupon the brute choked to death. That night the boar's head, finely dressed and garnished, was borne in procession to the dining room, accompanied by carolers singing "in honor of the King of bliss."
