As to the permanency of wood papers there is still difference of 

 opinion, but every year sees improvements resulting in a more 

 lasting and durable fiber. 



Great Britain in 1903 imported altogether twelve million dol- 

 lars worth of paper pulp, 554,000 tons, of which four million for 

 mechanical pulp (343,000 tons). Of greatest interest is the ex- 

 tension in the use of wood pulp, namely as a substitute for jute 

 and possibly coarse cotton yarn. There are two processes in 

 practical working. The one produces "xyloline", a strong yarn, 

 so cheaply that a whole suit of clothes can be sold for less than 

 two dollars which can be washed without damage. The other 

 produces "silvaline" for the same purposes, one factory being at 

 work in Spain, another in Holland, and others in Germany. 

 The use for nitro- cellulose (explosives), for cellulose wadding 

 (surgical bandages) and for artificial silk has been known for 

 some time. 



The use of the sulphite liquors for watering roads with excel- 

 lent results may solve the knotty question of getting rid of them 

 in some districts.

STATISTICS AND HISTORY. 



The rise and decline of the White Pine in- 



White Pine dustry is graphically shown by the statistics 



Famine of the lumber cut in Michigan, Wisconsin 



and Minnesota during the last 32 years. 

 Rounding off the annual output as given by the American lyUm- 

 berman, from year to year in billion feet, the series reads : 

 4- (1873). 3-5, 4-, 3-9, 3-6. 3-6, 4-8, 5-7, 6.8, 7.6, 7.6, 7.9, 7., 

 7.4, 7.8, 8.3, 8.2, 8.6 (1890), 7.9, 8.6, 7.3, 6.8, 7., 5.7, 6.2, 6.2, 

 6., 5-5, 5-3> 5-3, 4-8, 4-2, 3-6 (1905)- While in 1899 White 

 Pine still constituted 18% of the total lumber product, in 1905 it 

 is estimated to be less than half that proportion. 



If a change in prices for the last 15 years were noted in juxta 

 position to the above figures of cut it would have shown the op- 

 posite tendency in exaggerated form, and the date of the White 

 Pine famine would have been readily fixed about the year 1900,
