Near the center the surface of the tag was somewhat charred, but this was actually the extent of the damage. The safe contained a number of paper documents, which were almost entirely destroyed by

ery used in the dyeing of fabrics, cannot fail to interest a great industry in the United States, so pronounced are its advantages over the present system. The inventor is Mr. Carl Gruschwitz, of Zittau ; and the invention applies to that part of dyeing machinery called the "jigger," through which the goods pass at full width in the process of dyeing. The difference from the present method is that the dye is mixed in the vat itself, thereby doing away with the upper construction of reservoirs for that purpose in the present system. The dye is then distributed with force against the cloth by atomizers, instead of the goods passing through a body of liquid.

It is claimed by the makers that one man with one of these machines can easily cut ten cords of 2-foot wood per day, or 50,000 feet in logs, reducing the present labor expense at least fifty per cent.

W device—the invention of Mr. Miller R. Hutchison, of New York City—it is claimed that any deaf person, save one whose auditory nerve is paralyzed, can be made to hear. Fortunately, even among deaf mutes, there are comparatively few who are absolutely shut out from the reach-at least of some faint echo—of sound waves from the outer world. Deafness is in many cases only partial, being due to lack of, or defectiveness in, subsidiary parts of the ear mechanism, while the essential parts may be present in perfect working order. In such cases, what is needed is not an instrument that will merely amplify sounds, but one that will do the work of the missing or defective organic parts. It is on this principle that the "acousticon" is based. The instrument performs the function of the middle ear. In this airfilled cavity, as every student of physiology knows, are located the “ossicles”—

vided, in which both mouthpiece and earpiece are equipped with a nosepiece for gathering nasal sounds.
A special modification of the acousticon is a portable outfit for collecting
three small bones constituting a chain or bridge connecting the inner with the outer ear, and over which are transmitted to the fluid-surrounded extremities of the auditory nerve within the inner ear the vibrations caused by the sound waves as they roll in from the outer air and dash themselves up against the tympanum or ear drum. This chamber, owing to its being connected with the nasal passage through the Eustachian tube, is the portion of the ear most liable to affection by catarrh and other disorders, and hence the portion most often directly concerned in cases of deafness.
The acousticon may be described as a combined telephone and microphone. Its essential feature is a cup-shaped body, into the open end of which the soun: waves enter, the inner end of the cup

With the aid of this device, a young woman of twenty-two, who had lost sight and hearing at the age of six years, was able to enjoy the music at an opera in New York City, just as if she had never been deprived of any of her faculties.

reflecting and concentrating them upon a vibrating diaphragm. A small but powerful storage battery, capable of being carried in the pocket, is part of the mechanism; and it is claimed that there is no interference of reflected sound waves, such as often gives trouble in the case of ear tubes, trumpets, and horns. The articulation of words is made most distinct, so that even a faint whisper is heard by the deaf mute.
In order to enable the deaf person to eliminate from his attention certain sounds, and to concentrate his mind upon others, a special instruction outfit is pro

It has always been necessary to depress the keys of a machine sufficiently to throw the type-bar against the inking ribbon and leave its impression on the paper, this action releasing a universal bar, which allows the carriage to move forward one space as each letter is printed.

To Brigham Young may be traced the responsibility for the prospective loss of one of America's strangest wonders. He was the first irrigator in the West, and irrigation has worked the doom of Great Salt Lake. The drawing off of the waters was begun by Brigham Young in the forties. In 1880 the work he had begun was extended on a large scale, and, with its increased importance, the lowering of the lake level was most rapid.

The order calls for 100,000 yards of wire gauze. This is to be used to shut out the mosquito, where possible, while the breeding places are being destroyed so as to exterminate the pests. Mosquito brigades are to be organized in the canal villages under the direction of Colonel Gorgas.
