provided  for  in  said  act,  and  not  under  paragraph  105  of  said  act,  providing

Jet  buckles,  so  called,  made  of  glass  and  metal,  glass  being  of  chief  value,  of  a
plain  black  color,  are  dutiable  under  paragraph  112,  act  of  1897,  as  manufac-
tures of  glass,  and  not  at  60  per  cent  under  paragraph  100  as  "articles  of  glass,
cut,  engraved,  painted,  colored,  stained,  *  *  *  or  otherwise  ornamented,

under  paragraph  109  of  said  act. Paragraph  111  provides  only  for  completed

mounted  and  known  as  "projection  lens."  (T. D. 24280 — G. A. 5295;  March
6,  1903.)
