system yields the worst results, the shelter- wood compartment 

 system comes next, and then the systems which produce 

 uneven aged woods, the shelter- wood selection system being 

 best of all. 



On the whole, localities dill'er nuich ; some larely or never 

 suffer from storms, snow, etc., while others do so every year. 

 Such peculiarities must be takeri into account in selecting the 

 system.

Whether the one or other method of regeneration is the 

 more suitable, depends on local conditions. In some cases 

 artificial, in others natural regeneration by seed or by coppice 

 is indicated. More especially the importance of shelter-woods 

 in the case of middling nnd inferior localities must never be 

 overlooked, as well as in the case of those which are subject 

 to external dangers. Again, in some cases natural regenera- 

 tion is easy, in others difficult oi- almost impossible, and a 

 selection must be made accordingly. Another point is, that 

 trees standing in an uneven aged wood produce, as a rule, 

 more seed than those in an even aged wood. Finally, the 

 system which acts most favourably in respect of the factors of 

 the locality will also, as a rule, produce the most favourable 

 germinating bed for the falling seed.

 Woods yield timber, firewood, and a variety of minor 

 produce. As regards wood, a distinction must be made 

 between timber and firewood. Where only the latter is 

 wanted, that system is preferable which yields the largest 

 volume or greatest weight of produce within a certain space 

 of time. Where the ol)jects of management centre in the 

 ])roduction of timber, other considerations prevail. Such 

 production, if the timber is to be of any si/e, takes long 

 periods of time, and it demands ii continuous energetic action 

 of the locality. More especially a contiiuiously even degree of
