Bto.^9 across the lake, break them, and yet 

 yield them. 



Sub wind breaks are easily arranged and can 

 take various forms and sizes to suit conditions 

 as at K. 



Another kind of plantation, as already ^ 'er- 

 red to, is that which I call climatic, — the objects 

 of which have been explained. Their position 

 in a country among others is not so easily 

 reasoned, either scientifically or practically. 

 Area is obviously of more consequence than 

 form, because it requires a great field of leaves 

 to do what leaves are said to do in climatic 

 amelioration. M. with eight sides, and the 

 other with four, are designed as concentrated 

 masses adapted to Canada, and of course in 

 their case, more than other plantations, the cost 

 of establishment would be less per acre, and 

 would also better meet the item of revenue. 

 L. is an example of a conjoint-wind break and 

 climatic plantation. 



Canadian forestry, whatever its future, will 

 never realize all it should unless hand in hand 

 with science.

 permanent crop.
