For the party who has electric light in his house there is still an easier solution for the problem of power.  If the lighting circuit gives 110 volts he can connect eleven 10-volt lamps in series.  These will give 3 cp. each, and the whole set of 11 will take one ampere of current, and cost about the same as a 32-cp. lamp, or 1-1/4 cents per hour.  Simply connect the miniature circuit to an Edison plug, and insert in the nearest lamp socket.  Any number of different candle power lamps can be used providing each lamp takes the same amount of current, and the sum of their voltages equals the voltage of the circuit used.  This arrangement of small lights is used to produce a widely distributed, and diffused light in a room, for display of show cases, and for Christmas trees.  Of all these sources of power the two last are the most economical, and the latter of these two has in its favor the small initial cost.  These lamps are by no means playthings or experiments, but are as serviceable and practical as the larger lamps.  —­Contributed by Lindsay Eldridge, Chicago.

** How to Make a New Language [105]

Anyone possessing a phonograph can try a very interesting and amusing experiment without going to any expense.  Remove the belt and replace with a longer one, which can be made of narrow braid or a number of strands of yarn.  The new belt should be long enough to allow crossing it, thus reversing the machine.  This reverses every sound on the record and changes it to such an extent that very few words can be recognized.

** How to Make a Cup-and-Saucer Rack [105]

The rack is made of any suitable kind of wood, and the sides, A, are cut just alike, or from one pattern.  The shelves are made in various widths to fit the sides at the places where they are wanted.  The number of shelves can be varied and to suit the size of the dishes.  Cup hooks are placed on top and bottom shelves.  It is hung on the wall the same as a picture from the molding.  —­Contributed by F.

Reversing a Small Motor [105]

All that is necessary for reversing the motor is a pole-changing switch.  Connect the two middle posts of the switch with each other and the two outside posts with each other.  Then connect one of the outside posts of the switch to one brush of the motor and one middle post to the other brush.

Connect one bar of the switch to one end of the field coil and the other bar to one pole of the battery, and connect the other pole of the battery to the other field coil.  To reverse the motor, simply change the switch.
