The "Permanent Wave" of a Woman's 

 Hair and Its Secret 



ANEW process for making a permanent 

 waw in feminiiu' tresses has been 

 invented I)\' a Now \'()rk man. 



First of all the iiair is di\'idcd into a 

 greater numher of strands than has been 

 the usual practice. The part of each 

 strand nearest the head is wrapped roimd 

 a small ciirliny; rod. As it is wrapped 

 the hair is slii;luly twisted. The part of 

 the hair wliich lias been vva\ed previously 

 is allowed to fall free. 



The str.mds coiled around the turlers 

 are Ireatetl with a su|iersaturated saline 

 solution in the form of paste. This 

 saturated coiled portion of the hair is 

 then inclosed in a wrapping and heatetl 

 by encir;lin . the coil.^d hair with a 

 suitable hcator. 



A tempcr.uure of 800 degrees is 

 maintained for aI)out twcnt\- nn'iuites. 

 Then the heat is turned olT fjr fcjur 

 minutes, and turned on again for fi>ur 

 minutes. .After the hair has cooled it is 

 taken out of tlie coiLs and washed.

 in flannel and heated twice by electricity 



The sirens of old may have been more al- 

 luring but certainly no more mysterious 



The Lure of the Lorelei 

 Minus the Siren 



rHE song of the sirens has long been 

 stilled. The flowing deep has lost 

 its sweet-voiced, seductive inter- 

 preters and the wild waves whisper 

 enitinias. Instead, the voice of the 

 >,ixophone. the bugle or the bass 

 horn ma\' be made to steal along 

 the surface of the waters. 



The principle of the invention 

 which makes this possible is merely 

 the submersion of a watertight 

 coTnpartment with \ents for air 

 and a horn or other \ent connected, 

 through whi.h music may be simg 

 or plav'ed for the amusement of an 

 audience. 



The water-tight compartment: 

 is a box of glass with a steel frame — 

 or, it may be a leak-proof barrel 

 with a superstructure for support- 

 ing the instrument. A block-and- 

 tackle is attache<l so that it cati 

 be immerscti and raise<l at will. 

 The idea presentetl i> mx-ri to \ari.ition 

 and many amusing effects might bi- 

 obtainetl b\' the use of coiiceaUtl ventre 

 ill the place of the conspicuous horn 

 which is shown in the illustration.
