Machinery in store for sale may be kept in good condition by applying to the finishing parts the best of sperm oil. Ordinary lubricating oils are not suited to this use. ’ A Springfield (Mass.) watch maker c has perfected a self-winding watch. Electric batteries are hid in the upper part of the case, so that the clock is bound to wind itself once an hour by the opening and closing of the circuits. It is intended chiefly for offices and public buildings. 1 The master mechanic of a leading railway says that* his experience has led him to believe wrought-iron crankpins, piston-rods and axles are superior to steel- His views coincide with those of others. As to slides, a good quality of cast iron is choice, made sufficiently heavy to avoid any undue springing or liability to breakage. The Dunmore Iron and Steel Company at Dunmore, Pa., has a small switching locomotive of a novel pattern. It has three Bxl2 inch steam cylinders, four 33-inch driving wheels, two outside connecting and parallel . rods, and one inside connecting rod. No balancing is needed in driving wheels. It is claimed that by setting the cranks at an angle of 120 degrees the slip is reduced to a minimum. It would be safe to say that threequarters, if not more, of the finer grades of steel sold to consumers have to be worked up into shape by means of lathes, planers, millers or other tools; in fact, all tool steel not intended lor machine tools undergoes more or less “machining,” and yet hardly a pound is received from the makers in a state which permits it to be at once put in hand, as it must first be annealed.

The paper pipes for water and gas recently exhibited in Vienna, are rolled from sheets of paper and coated on the inside with enamel, the composition of which is a secret. In winding, the paper is soaked in melted asphalt, and the pipe is painted outside with asphalt varnish and dusted over with sand. It is claimed that the pipes will resist an internal pressure of two thousand pounds, although the material is only about half an meh thick.

The noise of injectors may be almost entirely stopped by the use of a little oil. A small, blind oil cup is placed on the top of the injector just back of where the steam enters. Pure petroleum should be used, having a fire test of 500 or 600 degrees, Crude petroleum contains volatile gases, which render the use of it for this purpose dangerous. Only a very small quantity of high-test oils need be used, and the effect of it in the boiler will tend to prevent the deposit of scale. Gold is shipped across the ocean in “specie kegs”, made of extra hard wood with an extra iron hoop, each bag containing SSOOO. In the interests of security, each keg is treated to what is technically known among the shippers as the “red taping” process. At each end of the keg, in the projecting rim of the staves above the head, are bored four holes, at equidistant intervals. A piece of red tape is run through these holes, crossing on the head of the keg, and the end-; finally meeting in the centre. At the point of meeting the tape is sealed to the keg’s head by wax bearing the stamp of the shipper.

A large quantity of lime-juice comes from Trinidad. A tree yields on an .average about ten gallons of juice. . The limes are allowed to drop off and then passed first through the cutter, which rips them open, and next through rollers and a press to separate them. The juice is then exported either as it is or condensed by boiling, A barrel of limes yields seven gallons of juice. The cost of producing limejuice, including packages, should not exceed 6 pence a gallon. The essen- ' tial oil is extracted from the rind before crushing by grating on rasps with the hands. The oil thus extracted is called hand-made oil. A hundred j gallons of juice will yield by distillation about three quarts of the essential oil.

Chicago architects are discussing the possibility of glass and paper as building materia). Glass as a building material has many advantages from a sanitary standpoint. It is cleanly and easily kept unpolluted by disease organisms or disease-producing filth. It is non-absorbent and will not collect moisture, as is the case with wood or brick. It is a poor conductor of heat, save that received from the rays of the sun, which for health purposes is the most valuable. Paper also has its advantages when treated by certain processes. It can be prepared so as to be fire-proof and waterproof, and as a non-conductor of heat it is invaluable. It is no idle hope which calls up a vision of manufactured articles from glass and paper which will fill all the requirements of the building materials of to-day. There are three methods given with recent English experiments in the use of tar as fuel; 1. Injection into the furnace by means of compressed air, with atomizing apparatus. 2. Injection into the furnace by means of steam, with atomizing apparatus. 3. Feeding into the furnaces by simple gravitation alone or in combination with coke. In using tar it is fourd —that the heat is so intense that only the most refractory of fire-bricks, such as the best Welsh silica bricks, could be found to withstand it Furnaces lined with the best Stourbridge manot last out forty-eight hours, whereas, in ordinary work with ooke, they would last over eight months, continuous firing. The injection of tar by compressed air for metallurgical uses is of the highest value, as tine resulting temperature Is imuse.

Getting Even With the Teller. There is in Washington a small boy, not more than 10 years of age, whose indulgent mother keeps him well supplied with pocket money. This young man opened an account with the local savings bank some time ago, and on the Ist of April he had on deposit there about |35. Two or three days later he had a falling out with the teller of the institution. For nearly a week he tried to think up some method of settling the score, and at last he hit upon a plan. He went to the bank and drew out S3O from his store. Then he went over to the Treasury building, which is across the street, and had his three ‘'tens’’ cohverted into thirty “ones.” Next he proceeded to make out thirty deposit slips, each for sl. These he carried to the bank, one at a time, compelling the poor teller to make thirty separate entries in h s books. The following day this young fiend again drew out S3O. Again he visited the Treasury, but this time he had his money changed into silver quarters, bright from the mint. One hundred and twenty deposit tickets were then prepared, and a corresponding number of entries had to be made in that unfortunate teller’s big books. Then for three days an armistice was declared, but at the end of that time S3O was agaih drawn out, and this time when the boy visited the Treasury building it was dimes that he wanted. The regulation deposit slips were prepared once more, and the teller gritted his teeth when he saw that he was to be made the victim of that boj/s vindictiveness. At last the 300 dimes were all in the bank, and the young villain prepared to reduce the store of his to nickels, but he was notified that the bank w'ould insist upon the thirty days’ notice allowed by law, and for a time the teller rests. — Baltimore American.
