Americas. Of old 

 races the Peruvians, 

 Yncatanese, Mexi- 

 cans, Caribs, Natch- 

 ez, and some of the 

 mound-building 

 tribes deformed the 

 head. In later days 

 many tribes along 

 the Northwest coast 

 from Oregon to the 

 Tlinkit territory 

 have or lately have 

 had the fashion. 

 The method of ap- 

 plying the pressure 

 varied. Sometimes a 

 board was fastened 

 firmly against the 

 forehead, space be- 

 ing left between it 

 and the back board 

 of the baby -frame 

 for the head to grow 

 backward and up- 

 ward to a wedge- 

 form. Sometimes 

 bands of cloth or 

 bark were bound 

 around the head so 

 as to force the 

 growth either up- 

 ward or backward. 

 All sorts of classi- 

 fications of the va- 

 rious forms have 

 been suggested.

 ly striking: (a) The 

 " flat-head "wedge- 

 shaped ; (b) the long 

 cylindrical ; (c) the 

 " sugar - loaf." Ten
