]'M AllTIl'K'IAL FORMATION OF WOODS. 



reji;enerations or sowings. In such cases the plants are 

 taken from the parts which are too thickly stocked, and 

 consequently they are g(!nerally indifferently developed ; they 

 are frequently slow in coniiiiL,' on after transplantin;^^ and 

 rarely yield <^ood results.

Where plantings are conducted regularly on a large scale, 

 plants may he raised in home nurseries; and even if the plants 

 are purchased from nurserymen, it is desirable to have an 

 auxiliary nursery at home ; hence it is necessary to describe 

 here, in outline, the establishment and management of 

 nurseries. 



Nurseries may be temporary or permanent ; the former are 

 used for a few 3'ears onl}', generally to yield the material for 

 the planting of a particular locality, when they are abandoned 

 and a new nursery laid out elsewhere ; permanent nurseries 

 are used for a long series of years. Each has its advantages 

 and disadvantages. In the case of temporary or shifting 

 nurseries the cost of transport and the risk of damaging the 

 plants during transit are smaller ; on the other hand the cost 

 of laying out is greater, as it recurs every two or three years, 

 and they do not, as a rule, yield eijually good plants. Tem- 

 porary nurseries can be established in localities of the same 

 description as those where the planting has to be done ; hence 

 they may be desirable where distinct zones of vegetation occur, 

 especially in mountainous districts, also where the plants are 

 to be put out with balls. 



Permanent nurseries require to be manured from time to 

 time, but they yield better plants ; they are preferable in the 

 majority of cases, especially in more level districts, where 

 large numbers of plants are required year after year, and 

 where the transport is fairly easy and cheap. There is 

 l)ractically no ditference in the treatment of temporary and 

 pernuinent nurseries, except that in the latter case all 

 arrangenunits are of a more lastiiit/ nature.
