A Guard to Prevent You from Dipping 

 Your Pen Too Deep in the Ink 



A square of mica protects 

 your fingers from ink stains 



CUT out a small square or circle of mica 

 and slip it over your favorite penholder 

 about li in. from the pen point. A small 

 brad on each side will hold the mica exten- 

 sion in place. This arrange- 

 ment will serve as an ex- 

 cellent ink gage when dip- 

 ping the point in the bottle 

 and also as a guard against 

 ink stains. The mica square 

 will prevent the pen from 

 being dipped in too far. It 

 does not obstruct your view 

 of the writing; you can see 

 through the mica. Should 

 it become stained, washing 

 it in a little water will 

 immediately clear it.

A Liquid to Clean Silverware 

 Without Damage 



WHEN using silver polishes, it should 

 be remembered that some silver is 

 always removed in the cleaning process

 scratching, and 

 at the same time 

 leaves a bright 

 lustre. A very

liquid poli.sh can 



be prepared by 



mixing five parts 



of aqua ammonia, 



20 parts sodium 



hy posul phite, 



and ten parts of 



a m m o n i u m 



chloride in 200 



parts of water. The greatest distributor of 



silverware in New York city recommends the 



use of sodium hypo.sulphite in water.
