following figures, those for home supplies being rough estimates and 

 ])robably greatly underestimated: 



Imports of timber for the years 1913, iyi6, and 1917. respectively, 

 ran 11,600,000 tons, 6,300,000 tons, 2,300,000 tons, while native timber 

 felled in these years was, respectively, 1.000,000. 1.250,000. 3,000,000 

 tons, and the requirements for 191 8 were estimated at 6,000.000 tons. 

 In words, the total consumption in the four years of war was almost 

 halved, and the home supplies were trebled and are to be sextupled. 



Most of the imports, about 70 per cent, came from Haltic sources, 

 and 50 per cent from Russia alone. The author foresees difficulties in 

 securing such a proportion from these sources after the war in compe- 

 tition with other nations needing materials for reconstruction, and 

 agrees that Canada's ex])ort. which in 1913 sent only 10 per cent of the 

 British import, could be greatly increased. The author makes the com- 

 mon mistake in according to Canada "unlimited" timber resources. He 

 also uses the argument of coming scarcity of supplies to support at 

 length the afiforestation schemes which have so many years been brew- 

 ing and which the war experiences may really bring to fruition.

Pointing out the new significance which forests 

 Forest and forest products have experienced during the 



Productioti war, Arnould insists that better statistics of forest 



;';/ production of France are needed after the war. 



France There are statistics for the years 1882. 1892. 



1900, and 1912, which the author analyses, com- 

 pares, and draws deductions from. It appears that the first three sets 

 of figures do not differ very much, but that the statistics of 191 2 show 

 a slight decrease. The forests are divided into three groups, namely. 

 State, communal, and private forests. For State and communal forests 

 the figures are fairly accurate, but for jjrivate forests they rely upon 

 uncertain estimates. The total production for 19 12 is stated as 830,- 

 6(p,ooo cubic feet, of which nearly 30 per cent are workwood. To this 

 is added, for the production from ]K)i)lars ])lanted along highways and 

 hedges, 63,340.000 cubic feet, luaking a total of 8<)4, 230,000 cubic feet. 

 In the statistics no differentiation is made as to the species involved, 

 excepting for domanial and (.-onimunal forests for iS()j only, when a 

 differentiation was madi- into hroad-leaved and resinous woods, and 

 within these two groups into wood above 20 inches in diameter and 

 wood less than 20 inches, poles and iniiu' pmps .ind fnrlwDod. in the
