From the Official Report of 
JAMES H. BOWEN, 
Unitecl States Commissioner to the Paris Exposition of 1867. 
The exposition abounded with specimens of pasteboard 
prepared for roofing and for lining rooms. It is usually pre¬ 
pared with bitumen so as to be more or less waterproof. The 
examples were most numerous in the Prussian and Austrian 
sections. In the Prussian, B. Dahse exhibited bituminous 
“carton-pierre” and bituminous pasteboard; Engell & Co., 
bituminous pasteboard for roofing ; E. A. Lindenberg, Dantzic, 
asphaltic paper for roofing; J. C. Leje, pipes of bituminous 
paper and roofing pasteboard. In the Austrain section, C. 
Haller exhibited incombustible and impermeable roofiing 
paper, and F. Sterba, bituminous and roofing paper. 
This description of material is now coming into extensive 
use in the United States, particularly at the west, where it is 
so often required to erect dwellings with expedition and 
economy. The Rock River Paper Company of Chicago man¬ 
ufacture an article which .they call “ sheathing and roofing 
board.” It is a coarse, yellow pasteboard, made in rolls of 
various lengths, and thirty-two and forty-eight inches wide. It 
is made very compact and firm—the fibers being closely 
pressed together at first, and then subjected to an enormous 
pressure and calendered down until the whole is made stiff 
and hard almost like a piece of board. It has a straight, 
smooth edge, and weighs about one and a quarter pounds to 
the square yard.
