 Popular Science Monthly The Brainless Drink-Mixer. It Never Makes a Mistake

IT is said that an efficient drink- mixer is a rarity because it is practically impossible for a man to make two drinks, com- posed of the same ingredients, taste alike. But with the drink mixer invented by Nicholas Jacovatos, of New York city, the mixing is done automatically and carelessness is eliminated.

His drink mixer resembles an ordinary ice-water cooler. In the interior are a number of compart- ments holding different flavors or liquids. The compartments are filled through tubes which extend to the outside, avoiding the incon- venience of lifting the cover to replenish the supply. One side of each compart- ment rests against a chamber containing ice, which keeps the contents at a con- stant temperature.

To obtain a mixed drink, the operator turns a lever, which causes a valve con- nected with it to mesh first with one compart- ment and then with another, until the several liquids which make up the desired concoction have all been released into the glass.

��HILE all the western world is echoing the slogan " Do It Elec- trically," and pulling down old ma- chinery in order to install new devices requiring fewer operators, China is still employing the man- power tread-mi lis shown in the accompanying illus- tration. Here men, women and children take turns keeping the mill going and thus pumping water into the reservoir seen at the left of the picture.

The four treads of the mill are supported crude framework.

A Floating Match-Safe Made from a Shaving-Stick Container

CERTAIN brands of shaving sticks come in strong metal containers which may be converted into useful match-safes for the camping outfit. These boxes hold fifty matches, which are enough for the use of one man for two weeks.

Although the cover fits well, the match- safe will not be waterproof unless a strip of adhesive plaster is wound around where the cover joins the box.
