Crownlands department that a series of experiments will be con- 

 ducted during the winter of 1910-11 in burning brush in the Rainy 

 River district. The result of this work will be watched with 

 interest in the United States where the northern pine forests are 

 so badly in need of adequate protection. 



A $4,000,000 paper mill has just been established at Toma- 

 kamai, Japan, in which all the heavy machinery was manufac- 

 tured in the United States. The daily output of this mill is about 

 70 tons each 24 hours which is over one-half of the amount con- 

 sumed for news and book paper in the entire empire. The avail- 

 able supply of native timber is estimated to last 50 to 100 years. 

 It is believed that Japan will now become an exporter of wood 

 paper. 



A shipment of 70,000 railway ties of "stringy bark" {Eucalyp- 

 tus obliqna) left Hobart, Australia, in October for the United 

 States and two shipments of the same size will be made in March 

 and June, 191 1. The species lasts 15 years or more as a tie where 

 the precipitation is 20 to 60 inches; the wood is not easily in- 

 flammable, holds spikes well and is comparatively immune from 

 the attack of white ants and other land insects. 



Formerly shuttlewood was secured from Turkish boxwood 

 which was imported from countries near the Black Sea. About 

 25 years ago the makers of roller skates commenced using this 

 wood and increased the prices so that native dogwood and per- 

 simmon were substituted, the former being preferred. The 

 limited supply of these species has led to present experiments with 

 Pacific dogwood, California valley mahogany, cascara buckthorn, 

 madrona, goldenleaf chinquapin, Pacific yew, and red gum. 



Cork oak is being experimented with at Brownsville, Texas. 

 It is said that a barrel of acorns is planted each year and that 

 wherever live oaks are found growing on the shifting sands in 

 this vicinity that cork oak will also thrive. The trees of cork 

 oak already planted are making a good growth. 



Japanese oak is being used to a considerable extent along the 

 Pacific coast owing to the high freight rates on the better grades
