 which you must lay on the lower lip of such trench. 

 Place the tree in the trench, and to fill it up, instead of 

 using the removed earth, throw down a sufficient quant-

 soil of the slope is rocky, and only covered with a thin 

 layer of turf, you must proceed exactly on the same

 only diiFerence is, that the first turf must be laid on 

 the lower lip of the trench, and the turt from the upper 

 lip must be put at the bottom of the trench. And, 

 finally, mould must be brought to cover up the roots of 

 the young plant. 



Lastly, should you wish to plant in places where the 

 naked rock appears at the surface, trenches must be 

 sunk in the rock and filled with earth from extraneous

 a large scale for the last few years. In Canada, fortu-
