The walnut plantations at Point Platon, A. Joly de Loteinieke {Canad. 

 Forestry Jour., 16 {1920), No. 7, pp. 32-3-329, figs. Jf). — Notes are given on the 

 present condition of three black walnut groves that were planted by the au- 

 thor's grandfather 37 years ago at I'oint Platon, Quebec. 



Trees were planted on three different sites, a cultivated soil protected on all 

 sides from tlie wind, an alluvial soil protected from the wind on one side only, 

 and on an exposed bowlder clay soil. The results in general indicate that pro- 

 tection from the wind is the keynote to success in planting the black walnut in 

 a cold climate, providing the trees are planted on a good soil and are given a 

 fair start. Walnut trees growing in the open required 9 years to grow an inch 

 in diameter, as compared with 5 years for protected walnut trees and 6 years 

 for paper birch, chestnut, and oak.
