One of them measured around 400 cubic feet, 140 feet in length. 

 (This may furnish in the neighborhood of 3,000 feet b. m.) The 

 net return to the commune for the twenty-nine trees was a little more 

 than $2,000, or, say, $70 per tree and 24 cents per cubic foot: in the 

 log; and, since the cutting cost 2 1/3 cents, this- may be translated 

 into around $26 per M feet stumpage. Transport and other charges 

 increased the cost to the purchaser on board cars to nearly 50 per 

 cent more.

Contradicting his former opinions, Professor 



Douglas Somerville, of Oxford, reports a series of obser- 



Fir Oil vations, accompanied by soil analyses, showing 



Limestone the adaptation of Douglas fir to limestone soils. 



"It would appear that the species may be plantec' 



with confidence on soils overlying chalk, provided the top 12 inches 



or so is thoroughly disintegrated, and especially if a previous crop 



of harciwoods or underwood has left the surface rich in humus." 



It grows even quite satisfactorily — at least for eight to ten years — 



with chalk found at a depth of six inches. 



Even where solid rock occurs within two feet of the surface, the 

 author would recommend the planting of Douglas fir. 



We may add that probably not the chemical constitution of lime 

 soils, but the geological formation, which in limestone is often a 

 horizontal layering, and the lack of fissures for water and deep-going 

 roots to penetrate may account for the observed lack of success on 

 limestone soils by certain species (chestnut).

In a brief note Schonberger points out that 



Swiss during the war much more wood is cut in Switzer- 



Porestry in land than the increment, for instead of an im- 



IVar Time ported deficiency in 1913 of about $7,000,000 



worth, for li)l."> an excess of nearly $2,000,000 



worth is recorded, /. e., a difference of $9,000,000. Yet to secure the 



requirements of paper mills the government threatened forcible
