��The flexible character of the key-bars permits the operator to exert a greater or less pressure without materially affecting the movement of the rotating disks, and thereby enables him to accent the musical strains. The water used should be well

acidulated and a quantity placed in the cup-shaped retainers on the upper sides of the disks. More or less of this water will flow over the rubber bands during their turning movement and thus constantly provide sufficient moisture to produce the best results.

��Electricity Used to Start a Balky Horse

A PENNSYLVANIA farmer who owns a valuable horse, cured it of the habit of balking by using electricity. He pur- chased a small storage battery, connected it with wires to the bit and crupper and placed the battery in the cart to which the horse was attached. When the horse re- fused to move and stood with all four feet braced, the owner touched the button connecting the lines with the battery. The horse received a slight shock and he snorted and jumped and began to move off at a lively pace. Every day for a week he was given the same treatment. As a result the balking habit was completely broken up. Upon investigation the local Humane Soci- ety decided that a little electricity is better than a whip. — Mrs. C. A. Wolfe.

��Handily Arranged Case for Holding Drawing Materials

THE drawing shows the construction of a convenient case to hold drawing materials used by the draughtsman, pen and ink artist or student. The outside di- mensions are 5 in. high by 6}/^ in. wide by 11^ in. long. A hinged cover 3^ in. thick, fastening with a hook or lock is provided. One end is partitioned off to hold ink bottles. The partition near the front has a raised bottom so that the ink bottle in use will rest with its top almost flush with the top of case. This bottle should be wedged in. Instead of using the regular filler-cap to close the bottle when not in use, the bottle is stoppered by means of a cork screwed to the hinged top of the case, as shown.

The cap is kept in the back

partition, a block with a hole in its

center being provided to hold the

point of the quill from the bottom

of the case. Thus as soon as the

lid is raised the ink is ready for use.

While being used the filler cap may

be kept in the bottle. Space is left

in the middle partition for a spare

bottle of ink with its cap. These

bottles should rest on pieces of blotting

paper to absorb any ink which may be

spilled. Blotting paper is also placed in

the bottom of the partition where the filler

cap is kept.

A shallow wooden tray is set into the upper portion of the main part of the case.
