A Sandpaper Label for the Poison To Make Your Shoes Last Longer, Bottle Gives Warning in the Dark Oil Them Occasionally

��PERHAPS the simplest for protecting people doses from poison bot- tles by mistake, is the sandpaper label shown in the accompanjdng illustration. The act- ual label with its usual skull and crossbones is pasted on a piece of sandpaper large enough to go all around the bottle, so that when you take up the bottle in the night, no matter how dazed from sleep you may be, the rough unfamiliar feel of the sandpaper rouses you, and you recognize at once that the bottle contains poison of some description. The printed label will tell the kind.

��A Trolley Hoist for Handling Coal

IN small boiler plants where coal has to be transferred from an outside bin to the fur- nace doors, the small electric, cord-operated trolley hoist shown in the accompanying il- lustration solves the problem economically in almost every case. The hoist shown is filled by hand but is self-dumping and self-righting. It has a carrying capacity of a half ton of coal.

The overhead trolley on which the hoist is suspended is carried clear into the boiler-room which is in the building shown in the background, so that one man, with simply the labor of filling the bucket, can keep a battery of boilers supplied with coal all day long. The bucket can be raised or lowered at will while it is traveling to and fro between the coal pile and the boilers by sim- ply pulling on the operating cord.

��should oil or grease it. To do this, first brush off all mud and then wash the shoe in warm water, drying it with a soft cloth.

While the shoe is still wet, apply the oil or grease, rubbing it in with a swab of wool, or better still, with the palm of the hand. After treatment, the shoes should be left to dry in a warm, but not in a hot place. Castor oil is recommended for shoes that are to be polished. For plainer footgear, fish oil and oleine or any one of the less expensive oils may be substituted with very good results.
