SECTION II. 

 Permanent and temporary nurseries compared. 



Whether a nursery should in any given case be permanent or tem- 

 porary is a question that is determined entirely by considerations 

 of convenience and expense. 



The nearer the nursery is to the site where planting is to take 

 place, the better, for the transplants will then suffer less in trans- 

 port and need not be lifted until almost the very moment they are 

 wanted, while the cost of carriage may thereby be indefinitely 

 diminished. Temporary nurseries, being intended to last only a 

 few years, one or more can be made in immediate proximity to, or 

 in the very middle of, each planting site of any extent, and aban- 

 doned as soon as the work there has been completed, new ones, if 

 necessary, being started further and further away as the planting 

 operations progress onwards. This could not obviously be done in 

 the case of permanent nurseries, which, as their name implies, 

 must be in constant use for an indefinite number of years and must, 

 therefore, serve a large area comprising near as well as remote 

 forests. For this reason a permanent nursery is generally much 

 larger than a temporary one. 



Once a nursery is established, it requires no further expenditure 

 on the preparation of the soil, on fencing, and on the supply of 

 means for watering it, except what is necessary for mere repairs 

 and maintenance. The initial cost of establishment is always com- 

 paratively heavy, but is incurred once for all in a permanent nursery 

 so that the expenditure per year and per plant raised becomes trifling, 

 whereas it constitutes a fresh charge each time a temporary nursery is 

 made and is distributed over only a few years and a hmited num- 

 ber of plants. And, indeed, on this account the labour and outlay 

 expended, in the latter class of nurseries, on the preparation of the 

 soil and on fencing and irrigation works are generally kept down 

 as low as possible, with the result that those of the former class 

 yield, on the whole, planting material of much better quahty. 



This result is also in a great measure due to the possibility, in 

 the case of permanent nurseries, of maintaining a more efficient 

 establishment, of exercising closer and more effective supervision 

 and control, and of observing, to the desirable extent, that continui- 

 ty of plan, method and purpose, without which success cannot al-
