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-

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 open- 
ings are numerous and 
ornamental, as shown in 
the anuexed cuts, and ex- 
tend 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, re- 
quire much less 
material than solid 
brick, and appear
