ultimate height of the tree. Another 

 hint, in regard to such a figure, is, that 

 some attention should be paid to the 

 forming of its top ; this would best be 

 done by selecting three or four side 

 branches, which grow nearly at the same 

 height ; as, by that means, the sap, much 

 reduced in quantity by the lower tier of 

 branches, would require to be equally di- 

 vided among the top ones. When treat- 

 ing of dead tops, it was remarked, that 

 the danger from such circumstances was 

 chiefly applicable to hard woods, such as 

 the oak, &c. 



The causes of dead tops have been 

 particularly attended to, (p. 123 — 132). 

 Their cure, wliere practicable, may be ef- 

 fected by the following means. When 

 such happen to trees infested with unna- 

 tural branches, they must all be taken off 

 as close as possible ; afterwards, the trees 

 should be scarified all the length of the 

 stem. The track of the knife, or tool.
