Just How You Wear Out 

 Your Clothes 



WE speak, and speak correctly, of 

 "wearing a suit of clothes" when 

 we have in mind only the use of the 

 clothes; but the garments are literally 

 worn away. We might also speak of 

 "wearing" bed- 

 clothes, because the 

 fibers of the bvd 

 linen are worn away 

 in much the same 

 manner as a car- 

 penter wears away 

 the surface of wood 

 when he sand- 

 papers it. Draughts 

 and other air cur- 

 rents waft these 

 fibers to and fro 

 until they collect 

 in small clusters of 

 "Huff." The "bits 

 and cantles" that 

 ha\c begun to at- 

 tract others to them 

 gather more and 

 more, imtil a large 

 proportion of the 

 aerial flotsam has 



been transformed into what the house- 

 keeper calls "little rolls of dust" that she 

 finds under the bed and in the corners. 

 These are fibers that friction has removed 

 from the bed linen and from one's 

 clothing. 



Whenever cloth is handled, some 

 fibers are rubbed off and in time become 

 visible and objectionable. The forma- 

 tion of this fluff is not unlike the growth 

 of snowballs that boys roll. 



I'nder the microscope, especialK' with 

 reflected light, these balls of fluff are 

 wonderfully beautiful, gleaming with a 

 brilliancy that cannot be captured by 

 a photograph. 



end of which is inserted a round steel 

 die, containing hatched lines. This 

 steel die revolves and its surface comes 

 in contact with an ink pad placed inside 

 the holder. The check to be protected 



is phued

 the hatched wheel 

 of the protector is 

 brought into po- 

 sition on the sur- 

 face of the check, 

 o\er the written 

 amount. With a 

 slight pressure the 

 wheel is slowly re- 

 \-olved across the 

 face of the check. 

 The re\'ol\ing 

 wheel lioth prints

A New Check Protector No Bigger Than 

 a Pocket Match-Safe 



ANEW check protector has just been 

 in\ented by an Oakland, California, 

 man. It is so small and compact that it 

 resembles a pocket cigar-lighter and 

 can be carried in a vest pocket as casiK- 

 as a match-safe. 



It consists of a metal holder, at one
