An account by Mr Cruicksliank of the most eco- 

 nomical and successful mode of planting moors 

 and Weak mountains, ... P. 340 



Method of planting" by the flat dibble or single notch, 343 



by the double notch or cross-slitting, 344 



Expense and comparative merits of each, . . 345 



These methods of planting best adapted for a sterile 



country, where the weeds are small, , . 346 



Practice by the writer of cultivating young plan- 

 tation by the plough, suited for rich soil, . 347 



Best season for planting moist soils, . . 348 



Manner in which frost throws up the young plant 



from the soil, ..... 349 



IVIr Cruickshank's plan of raising oak forest in situ 

 from the seed, . . , .351 



That although the bare plan given by our author, of 

 sowing in situ, under the shelter of nui'ses, is 

 good, his directions for executing it are not very 

 judicious, ..... 352 



Advantages of this plan which Mr Cruickshank has 

 not noticed, ..... 353 



That the power of ripening seed is not increased by 



shelter in proportion to the power of growing, 356 



That the line of seed ripening, and not the line of 

 growing, regulates the natural distribution of 

 plants in respect to climate, . . .357 



That oaks, under this plan of sowing in situ under 

 shelter, can be extended to a climate inferior to 

 the natural, . , . , . ib. 



That oaks grown in the low country, and best cli- 

 mate of Scotland, appear not to ripen the seed 

 sufficiently. Thence the probability that oak now 

 would not even keep its present locality in the low 

 country of Scotland, although it may " be taught 

 to rise in our" alpine country, . . . 358
