52 Forestry Quarterly 



Since the Spring of 1901, the Forestry- 

 TV^^ Planting Branch of the Canadian Department of the 

 in Interior has co-operated with settlers on 



Canada. the western prairies in the formation of 



shelterbelts and farm woodlots. Seedlings 

 have been furnished free, about two million having been sent out 

 during the season of 1905. About 75% of these consisted of na- 

 tive Green Ash and Boxelder, the former having remained two 

 years in the nursery and the latter only one. 



Small areas' at the Brandon and Indian Head Experimental 

 Farms had previously been used for nursery purposes, but in the 

 spring of 1903, 160 acres were secured, a mile south of the town 

 of Indian Head in the new province of Saskatchewan, on the 

 main line of the Canadian Pacific Railway. This area will be 

 devoted exclusively to nursery and demonstration work. Culti- 

 vation has been begun, and buildings and fences erected. 

 Hedges and shelterbelts have been planted, and a small begin- 

 ning made in the raising of seedlings for distribution. Conifers 

 have been raised to only a small extent so far, Colorado Blue 

 Spruce {^Picea pungens) giving the greatest promise. 



Cultivation of the broadleaf varieties is done b}' horse cultiva- 

 tors, the drills being 30 inches apart. 



The young conifer seedlings are protected by lath screens for 

 two years, then transplanted to rows ten inches apart, where they 

 remain two years longer before being set out in permanent plan- 

 tations. Cultivation in the plantations is done by means of the 

 double wheel hand hoe. 



It is expected that an annual output of from three to four mil- 

 lion seedlings will be needed in order to supply the future demand,

MENSURATION, FINANCE, AND MANAGEMENT. 



While we are still wrestling with the crude 

 Increnieyit methods of determining increments, Fried- 



Autograph rich has devised instruments for studying 



the finesse of accretion, by which the 

 daily growth can be measured. He used these increment auto- 

 graphs for studying the influence of weather on increment and
