slopes of our mountains, and the prairies of the North- 

 "West, which are, in many places, absolutely tree-less. 

 "We will now see how to proceed in planting the soils in 

 question. 



Rocky soils. — On these soils, wherever you intend 

 to set a tree, first raise the turf which covers the rock ; 

 then, make a trench in the rock large enough to contain 

 the roots of the plant, or the walnut or acorn, if you 

 work by seed ; put the turf at the bottom of the trench, 

 and cover it with the surrounding soil. This should be 

 done ill spring, and the plantation or sowing in these 

 branches the following year, at the same season. The 

 turf will become a rich mould, which will assist the 

 growth of the young plant, and success is certain. 



Wet soils. — For wet soils, a perfectly opposite treat- 

 ment is necessary ; that is to say, instead of hollowing 

 out the land, you must raise it in this fashion : place the 

 plant on the surface, and spread out its roots with care ; 

 cover them with good mould, enough to keep them up- 

 right, and lay turves, taken from round the spot where 

 the plant is placed, on the mould, taking every pains to 

 60 adjust them that all the mould shall be covered, and 

 no fissure left between the turves. This system of 

 mound-planting has been successfully practised in Europe 

 for many years, and is suitable to all soils, even to the 

 driest. A Canadian amateur has succeeded well with 

 it (engraving 102, p.. IIT, gives a perfect idea of the 

 method) ; hence, I can recommend the practice with 

 confidence. Drainage should be carefully attended to 

 when you intend to plant on mounds ; but even in places 

 where drainage is impossible, there is a fair chance of 

 success. 



Mountain-slopes. — If, as sometimes happens, the slope 

 is covered with a good bed of vegetable mould, you
