able remarks have been already quoted, adds these 

 warnings upon this mode of pine culture : — 



The young suckers on the old stool ought to be 

 always growing, but in very dark weather 65 degs. 

 during the day will suffice, and answer a better pur- 

 pose than a higher atmosphere, supported by enor- 

 mous fires. With a humid atmosphere, they will 

 make much progress even during the winter ; at least 

 his plants do. Dormancy and dry air are both posi- 



I tively injurious, particularly a dry air ; the leaves will 

 become debilitated, and their energies so impaired that 

 they will be very unfit to meet the exigencies of the 

 plant when the growing season arrives. The pine-leaf 

 should be so brittle that it can scarcely be touched 

 without breaking ; and when such leaves are cut vnth 

 the knife the sap will directly ooze out from the inner 

 tissue of the leaf. In this state they are prepared to 

 meet a July sun. (Ibid, 1846, 252.) 



The following observations by Mr. Errington apply 

 to all modes of culture : — 



When you cut your fruit avoid as much as possible 

 any damage to the leaves. Preserve by all possible 

 means your old roots. Young or stem roots are all 

 very good adjuncts, if honestly obtained ; let them 

 not, however, be petted at the expense of the original 

 roots. If two suckers are left equally in a perpen- 



I dicular position, and the agencies pointed out by the 

 Hamiltonian method applied to promote rapid growth.
