In a series of ore beds formerly operated by a mining company of northern New York, four distinctions of the crude ore were made, two varieties of blue, one of black, and one of gray. The blue coloring is apparently due to the presence of impurities; the black ore is evidently magnetite; and the steel-gray mineral, failing in the characteristic properties of magnetite, finds its class place under hematite. Hematite differs from magnetite in representing a higher degree of oxidation. It is often found, as indicated above, in beds distributed in close conjunction with those of magnetite. This ore is a valuable source of iron. Hematite commonly occurs in earthy materials, as red ochre. Its streak is red. All rocks of a reddish or red color owe the color to this oxide of iron. When hematite rusts, the brownish-yellow or yellow iron oxide, limonite, results. The streak of limonite is yellow, thus distinguishing it from hematite. Disseminated through beds of clay, limonite gives them the characteristic yellow color. Such clays turn red when heated, since the water of the limonite is driven off, leaving hematite as a residue. This is the explanation of the usual coloring of bricks. Yellow ochre is impure, or earthy, limonite. WHEN ANIMALS ARE SEASICK. PHEBE WESTCOTT HUMPHREYS. Anyone who has traveled extensively has had an opportunity in some of the ocean voyages to witness the seasickness of animals, and many queer stories are told from time to time of their actions at such times--how lions become un-kinglike, monkeys ape humanity, and dogs are especially woeful--and one realizes that human beings are not the only ones that suffer from seasickness, by any means. One hears a good deal about pangs that have filled the men and women with woe, but little is said of the menageries brought to America every year, or carried hither and yon in wave-tossed boats. Lions and tigers may be majestic when they have unwavering earth or rock against their paws, but a seasick cat of these tribes is as forlorn as any man ever was, and doesn't look a bit more kingly than a wet rabbit. Even its roars and growls have a weeping sound in them, quite in keeping with the general appearance of the beast. A monkey is as pitiable an object when it is seasick as any other beast so stricken, and its forlorn facial expression is so humanlike and the way it clasps its paws across its stomach is so natural that the man who is not seasick necessarily sees something to laugh at in the misery of the creature. Not so with the seasick man. If he sees a seasick monkey he is sure to get very angry, thinking the poor thing is mocking him.
