2310 ARBORETUM AND FRUTICETUM. PART III. 



main object is to produce timber trees ; or by cutting out the largest when fit for 

 poles, it" this be the main object. Very little pruning is required for the spruce 

 fir, except in the case of large trees ; when the lower branches may be cut 

 off close to the stem, to the heighth of a fourth, or from that to a third, part 

 o( the height of the whole tree. When pruned, the branches ought to be cut 

 off close to the stem, in order that the wound may heal over as speedily 

 as possible. Hayes mentions a practice adopted by a gentleman in Ireland, 

 of cutting oh 1 ' every other tier of branches, for the purpose of strengthening 

 those which were left; and, by allowing the branches to hang down more 

 freely, thus to increase the picturesque appearance of the tree. (Pract. 

 Treat., p. 166.) At whatever age the trees are cut down, the roots ought 

 to be grubbed up, as they furnish a valuable material for fuel or charcoal. 

 The season of felling, where the bark is to be kept on, should be mid-winter, 

 when the sap is in its most dormant state : but, where the bark is wanted for 

 tanning, May is preferable ; because then the sap is in motion, and the bark 

 easily separates from the wood.
