Fibre for Paper Pulp; by Chevalier De Craussen, (Proc. Brit. As- 
soc., 1855; Athen., 1457.)—The paper-makers are in want of a ma- 
* terial to replace rags in the manufacture of paper, and I have therefore 
turned my attention to this subject, the result of which I will commu 
nicate to the Association. To make this matter more comprehensible 
I will explain what the paper-makers want. ey require a cheap

white paper pulp. Surat, or Jute, the inner bark of Corchorus indicus, 
produces a paper pulp of inferior quality bleached with difficulty. 
gave, Phormium tenax, and banana or plantain fibre (Manilla hemp), 
are not only expensive, but it is nearly impossible to bleach them. The 
banana leaves contain 40 per cent of fibre. Flax would be suitable to 
replace rags in paper manufacture, but the high price and scarcity of 
the fibre reduce 
By the foregoing it will be seen that the flax plant only produces 
from 12 to 15 per cent of paper pulp. All that I have said about flax 
ed. The Bromeliacee contain 25 to 40 per cent fibre. Donda- e" 
partea juncoidea contains 35 per cent of the most beautiful vegetable | 
fibre known ; it could be used not only for paper pulp, but for all kinds
