The  followiug  drawings  show  the  forms  in  which  the
Company  manufacture  paving  tiles  of  excellent  quality,  far
better  thau  the  ordiiiary  paving  brick  in  common  use  in  the
United  States,  for  want  of  forms  better  adapted  to  the  pur-Ringofen-Ziegelei

  der  Stadtgemeinde,  Troppau.  This
establishment  exhibited  in  the  Austrian  court  a  series  of
remarkably  smooth  and  well-formed  pressed  red  brick,  and
square  slabs,  and  paving  tiles.  The  latter  were  both  yellow
and  red,  in  hexagons,  about  eight  inches  across;  and  in
rhombs,  same  size,  and  two  and  a  half  inches  thick.  A
fine  cfl'ect  is  produced  by  laying  the  two  colors  alternately.
The  large  slabs  were  twelve  inches  square  and  three  inches
thick.  A  variety  of  angle  and  cornice  bricks  were  also
shown.  The  ordinary  brick  shown  measured  about  llf  X
6x3  inches,  or  say  12x6x3  inches.

Perforated  Brick—England.
George  Jennings  Pqole,  Borset,  England,  exhibited  a
variety  of  perforated  bricks,  red  and  of  a  light  gray  color,
about  9x3x2  inches,
and  some  square  slabs  9
inches  each  way  and  2
inches  thick.  The  openings
  are  numerous  and
ornamental,  as  shown  in
the  anuexed  cuts,  and  extend
  through  the  brick  from  side  to  side.  Ihese  bricks
are  evidently  made  in  machinos  similar  to  those  used  for
drain  tiles.  They
are  very  light,  require
  much  less
material  than  solid
brick,  and  appear
