Hitherto wood-flour, though used for a variety of other technical 

 purposes, has only been utilised in the manufacture of pulp to 

 a small extent. For the manufacture of the saw-pulp used at 

 the Donside Paper Works a grinding mill was acquired at 

 Kinghorn, Fife, and as a result of the experiments which were 

 carried out with this material at the paper mills, it was found 

 that the most satisfactory results could be obtained by mixing 

 the saw-pulp to the extent of 35 per cent, with 30 per cent, 

 of waste (paper), or altogether 65 per cent, of home material 

 and 35 per cent, of imported pulp, the proportions which had 

 previously to be used being about 70 per cent, of imported 

 pulp as compared with 30 or 40 per cent, of home materials. 

 It is estimated that 20,000 tons per annum of saw-pulp can 

 be obtained from the United Kingdom, which would form a 

 considerable addition to our paper-making materials.

 considerable interest and service to the forestry world have 

 been produced. 



The present volume purports to embody "the results of a 

 study of the more important phases of forest practice in 

 Corsica, Algeria, and Tunisia." No attempt is made to give 

 a complete investigation of forestry in all its branches. Nor 

 does the writer summarise all the details of administration ; he 

 rather aims at setting forth the essentials of method applicable 

 to the United States or of value to English-speaking foresters. 

 Only methods and results are set forth, and no comparisons are 

 made. 



The book is divided into three main parts, namely, Tunisia, 

 Algeria, and Corsica. There is also an appendix giving a
