It is already common practice to provide a single-rail switch for throwing one rail of the siding out of alignment, and ditching the car should it start for the main line, but it is an easy thing to bridge over the While probably not so requisite an adjunct of the culinary department of the American household as in Continental Europe, nevertheless a cheesegrating machine would doubtless be welcomed in many kitchens. It is quite a small device, being only eight inches long and four inches deep. A cylinder of cheese less than two inches in diameter and about three inches long, is inserted in the machine, where it is held between two grater discs, against which it is strongly pressed by a powerful spring in an extension tube at the end of the body.

Turning the crank is all that is necessary. A small drawer is provided beneath to catch the cheese after it is ground. This device hails from Germany.

Hofmann and Strauss have obtained radioactive salts of lead from various rare minerals. The radio-active lead differs in many respects from ordinary lead in its chemical behavior, but it has not yet been obtained in its pure state.

All the various salts have a similar action upon the electroscope, but only the sulphate is capable of acting upon a photographic plate through glass or aluminum; moreover, the sulphate becomes particularly active in the latter respect aftc-r having been evaporated by nitric and sulphuric acids or after having been ignited at 4.10 degrees for fifteen hours with access of air. It appears also that while radioactive lead sulphate acts more energetically on a photographic plate than certain polonium (radio-active bismuth) preparations the latter have a much greater action in discharging the electroscope. It follows from this that the rays detected by photographic means are not identical with those that produce electric discharges. 44 ik 44 44 44 4 Packet letter head 14 5 It) 18 6 It) 20 8 lt 18 10tb .42 .51 .68 .85 16 4tt) Arcadia Commercial Note per 3(3 28 5tb 45 1 6 It) .54 letter heads 44 44 4 5 8 It) 2 12 it) 7 1.08 .60 .75 10 4 It) Oriole Commercial Note per M. 5 It) A New England Woman's Invention.

As an improvement over this form of safety appliance Henry E. Flower of Philadelphia, offers the lock shown in the cut, claiming that it can be instantly applied to the rail and locked against removal or being otherwise tampered with by any one other than the proper persons. The lock is divided into two main sections, one carrying the key mechanism and handle, and the other part forming a sliding jaw, engaging the interior bolts to hold it in place. The jaws are serrated on the under side, so as to grip the rail with more firmness, and the sliding jaw allows the lock to be used on rails of various sizes. To anchor a car on a siding the lock is dropped over the rail and the siding jaw closed as tightly as possible, when a turn of the key completes the work.

New Foe of the Burglar. The device shown in the accompanying drawing does not look icious enough to combat successfully with a burglar until you notice the wicked little gun way down in the corner of the picture. It is the hidden foe against which the burglar has no power to fight. The use of the electric current, with its numerous wires and switches, is already quite common as a protective agency, but the apparatus may become disarranged or the strength of the batteries diminish and the alarm prove ineffective just at the time it is needed. With this device there is the one movable platform and trigger operating mechanism, complete in itself, and sure to give an alarm as soon as the platform is depressed by the weight of a person stepping on it.

The device is rendered inoperative by throwing the oblique bars into a vertical position, which drops the horizontal bar against the support beneath and carries any weight on the platform above. Arrangement may be made to regulate this alarm by the opening of an inside door, thus throwing it out of action when a member of the family desires to pass out across the platform. The gun may be pointed so as 1.20 6 Reams 24x36 70 lb Canary S. S. C.

The chief feature of the apparatus is that it will cut through a drift or crust of packed snow about as easy as an ordinary plow removes a light drift. This is accomplished by first disintegrating the ice and snow with the revolving cutters mounted in the mouth of the plow, when it is an easy matter to dispose of the small sections. A motor is provided to revolve the knives, and the same power runs the endless elevator which projects upward from the center of the car.

Directly beneath the upper end of this elevator the roof takes the shape of the letter A. with the lower ends projecting over either side of the car. In action the flaring mouth of plow scoops in the snow, while the revolving knives mince it fine and drive it back to the elevator. Here it is lifted and falls on the sides of the slanting roof, passing thence to the ground on either side of the track. A turret above the knives affords a housing for the controlling motors and the operator who has charge of the machine.
