_Paper-making_.--The manufacture of paper has of late rapidly increased in the United States. According to an estimate in 1829, the whole quantity made in this country amounted to about five to seven millions a year, and employed from ten to eleven thousand persons. Rags are not imported from Italy and Germany to the same amount as formerly, because people here save them more carefully; and the value of the rags, junk, etc., saved annually in the United States, is believed to amount to two millions of dollars. Machines for making paper of any length are much employed in the United States. The quality of American paper has also improved; but, as paper becomes much better by keeping, it is difficult to have it of the best quality in this country, the interest of capital being too high. The paper used here for printing compares very disadvantageously with that of England. Much wrapping paper is now made of straw, and paper for tracing through is prepared in Germany from the poplar tree. A letter of Mr. Brand, formerly a civil officer in Upper Provence, in France (which contains many pine forests), dated Feb. 12, 1830, has been published in the French papers, containing an account of his successful experiments to make coarse paper of the pine tree. The experiments of others have led to the same results. Any of our readers, interested in this subject, can find Mr. Brand's letter in the _Courrier Francais_ of Nov. 27, 1830, a French paper published in New York. In salt-works near Hull, Massachusetts, in which the sea-water is made to flow slowly over sheds of pine, in order to evaporate, the writer found large quantities of a white substance--the fibres of the pine wood dissolved and carried off by the brine--which seemed to require nothing but glue to convert it into paper.
Is one of the most curious creatures of "the watery kingdom." It is popularly termed a fish, though it is, in fact, a worm, belonging to the order termed _Mollusca, (Molluscus_, soft,) from the body being of a pulpy substance and having no skeleton. It differs in many respects from other animals of its class, particularly with regard to its internal structure, the perfect formation of the viscera, eyes, and even organs of hearing. Moreover, "it has three hearts, two of which are placed at the root of the two branchiae (or gills); they receive the blood from the body, and propel it into the branchiae. The returning veins open into the middle heart, from which the aorta proceeds."[7] Of Cuttle-fish there are several species. That represented in the annexed Cut is the common or officinal Cuttle-fish, (_Sepia officinalis_, Lin). It consists of a soft, pulpy, body, with processes or arms, which are furnished with small holes or suckers, by means of which the animal fixes itself in the manner of cupping-glasses. These holes increase with the age of the animal; and in some species amount to upwards of one thousand. The arms are often torn or nipped off by shell or other fishes, but the animal has the power of speedily reproducing the limbs. By means of the suckers the Cuttle-fish usually affects its locomotion. "It swims at freedom in the bosom of the sea, moving by sudden and irregular jerks, the body being nearly in a perpendicular position, and the head directed downwards and backwards. Some species have a fleshy, muscular fin on each side, by aid of which they accomplish these apparently inconvenient motions; but, at least, an equal number of them are finless, and yet can swim with perhaps little less agility. Lamarck, indeed, denies this, and says that these can only trail themselves along the bottom by means of the suckers. This is probably their usual mode of proceeding; that it is not their only one, we have the positive affirmation of other observers."[8] Serviceable as these arms undoubtedly are to the Cuttle-fish, Blumenbach thinks it questionable whether they can be considered as organs of touch, in the more limited sense to which he has confined that term.[9]
