of late years from the extensive preparation of paper 

 pulp from wood. 



In the course of conversation with the gentlemen of 

 whom I have spoken in my account of my voyage on 

 Lake Saima mention was made of the manufacture of 

 paper pulp from wood, and when one of them was speak- 

 ing of the immense quantity of wood debris and saw- 

 dust with which he was encumbered in his operations I 

 jestingly said ' Why not convert it into wood pulp? ' His 

 prompt reply was ' Solely because we cannot do everything 

 at once.' 



By Hofrath A. Grippenberg, proprietor of the paper and 

 paper pulp manufactory of Kymmene and Ingerois, I was 

 informed the first Ingerois manufactory was built in 1873. 

 All kinds of paper were manufactured there, but their 

 speciality was paper to be used in the making of cigarettes ; 

 what pulp they made was for use in the work chiefly, and 

 very little for exportation. In making printing paper 

 they used 75 per cent, of wood pulp, with 25 per cent, of 

 rags. 



On the 1st June 1881 the mill was burned to the 

 ground, and it was rebuilt for the manufactory of paper 

 pulp and pasteboard only. The new mill was completed 

 by December. 16 turbines, with 800 horse-power, supply 

 the needed force. They use only firwood. They have 

 forests of their own, but they purchase also a good deal 

 of wood from others. 



The wood is cut into equal sized pieces, which are put 

 into what are called defibreurs, in which the fibres are 

 torn apart. In connection with it is a round stone kept 

 in rapid movement ; and a great deal of water being 

 employed small pieces of wood are washed along with the 

 torn fibres. All goes then to the sorting apparatus, 

 through which only very fine pulp passes, and the 

 remainder is pumped to another stone, by which it is 

 further disentegrated, and it is floated down, suspended in 

 a great quantity of water. It is then taken up by an 

 endless band, and brought to a room with a very high
