ation of the by-products, special mention must be made of Peter Klason. In
addition to turpentine and, in a lesser degree, resin-soap, which are obtained
at a number of the sulphate factories in the country, there are produced at
three of the sulphite works spirits, obtained from the sulphite-lye by a method
developed by the Swedish engineers) Ehstrom and Wallin. The amount obtained
from sulphite-lye during the period September 1, 1912—September 1, 1913,
was 4 313 992 liters 50 % spirits (cf. Spirit Production).

Although there has been a considerable development as regards the manufacture
both of mechanically produced pulp and of sulphate-pulp, this

development cannot be compared with that which has taken place in the
sulphite cellulose industry. The following Table and graphic figures show
how the total production of wood-pulp is distributed among the sulphite-,
sulphat- and mechanically produced pulp, both as regards the production
and the amount , exported. As regards the production, the report has been
supplied by Svenska cellulosaforeningen (the Swedish Cellulose Association)
