I which is shaded and sapped. The es- 

 timates are for annual income per acre, 

 discounted at the rate of 4 per cent 

 from the final value of the timber 

 when cut. No allowance is made for 

 . the cost of planting. 



Cottonwood rows and narrow belts 

 planted in fairly moist bottom lands 

 yield an income of from $2.64 to $8.01 

 per acre, the greatest values being ob- 

 tained by cutting after the age of 40 

 years. Good returns can not be ex- 

 pected from any but moist situations. 



Willow planted on thoroughly moist 

 soil yields from $4,17 to $1^81" worth 

 of posts per acre, the highest values 

 l)eing realized when cutting is done 

 between the ages of 14 and 20 years. 

 When utilized for fuel, willow yields 

 an income of from 72 cents to $2.78. 



Green ash yields from $2.53 to $6.51 

 in posts on the best class of soils, and 

 from $1.84 upward on poorer soils. It 

 is an excellent auxiliary to cotton- 

 wood, but will make good growth on 

 much more unfavorable situations. 



RE, PROF. MacPHAIL'S SPI-:i-:c"ll 



Editor, Canadian Forestry Journal : 



Referring to the recent address of 

 Professor MacPhail which \<iu dcdt 



with in the last issue of the "Journal" 

 it may be interesting to recall the 

 words of Mr. G. K. Chesterton, which 

 will be found at Page 56 of his enter- 

 taining little book on Blake: 



"The trouble with the expert is 

 never that he is not a man ; it is 

 always that wherever he is not an 

 expert he is too much of an ordin- 

 ary man. Wherever he is not ex- 

 ceptionally learned, he is quite 

 casually ignorant. This is the 

 great fallacy in the case of what is 

 called the impartiality of men of 

 science. If scientific men had no 

 ideas beyond their "scientific work 

 it might be all very well; that is 

 to say, all very well for evervbody 

 except them. But the truth is that 

 beyond their scientific ideas, they 

 have, not the absence of ideas, but 

 the presence of the most vulgar 

 and sentimental ideas that happen 

 to be common to their social cli- 

 que. If a biologist had no views 

 on art or morals, it might be all 

 very well. The truth "is that a 

 biologist has all the wrong ideas of 

 art and morals that happen to be 

 going about in the smart set in h.is 

 time."
