4. A better soil condition is assured under the mixture than under 

 pure spruce. 



5. The spruce growing faster than the fir and the price being the 

 same, a greater volume and value increment is secured. 



6. The character of the wood is about equal. 



7. The spruce is more frost-resistant and is not so liable to frost 

 splits as the fir. 



8. Due to its ability to grow in the open and rapidly outgrow weeds, 

 the spruce is of value for planting in the clearings and too large open- 

 ings in regeneration fellings. It is therefore the tree for reforestation 

 except on unsuitable sites. 



9. The species being the one tolerant, the other intolerant, they are 

 mutually advantageous to each other, the first protecting the soil, the 

 second enriching it by its abundant leaf-fall. 



The author recognizes, however, some objections to the spruce. 

 Wounds, even slight ones, exude resin and prevent wound-wood for- 

 mation and give access to fungus disease. Red rot often s])oils the 

 value of the wood, although the author has found 200 to 250 year trees 

 with hardly a trace of it. The bark beetle is another trouble. By 

 proper precautions the troubles can at least be diminished. ^Methods 

 of procedure are detailed.

Taylor, in the article under review, states that 

 The Seeds of the complete destruction of so many acres of 

 Forest Trees I'.ritish woodland, owing to conditions arising out 

 and Their of the war, has brought to the fore the national 



Place in im])ortance of forestry in a way that is practical 



British Forestry and forceful. He states that it would seem im- 

 possible further to defer adoption by the State of 

 a vigorous and comprehensive scheme of afforestation after 30 years 

 of inaction, since a select committee was appointed by the Government 

 to advise on the improvement of woodlands. In the report of 1909 it 

 was recommended that 150,000 acres be planted annually. Somerville, 

 in a more recent publication, mentions 300,000 acres as commensurate 

 with the needs of the nation. Taylor states that if the latter progran> 

 were carried out forest nurseries must be developed to gnnv 1.400,- 

 000,000 seedlings and transplants yearly. Even if only carried out in 

 part, there must necessarily be a large and sustained demand for forest- 

 tree seeds ; hence the consideration of actual and potential sources is of 

 importance. Heretofore the reciuirements of I'.ritish foresters for
