present difficulties in arrangement and maintenance. Before work 

 in a nursery is commenced a plan should be made showing all 

 permanent features (Fig. 48). 



Every large nursery should be permanently divided by roads 

 and crossroads into blocks or compartments, square or rectangular

in shape. The main roads should be 10 or 12 feet wide, and the 

 other roads 8 feet. A large amount of space where seedbed frames 

 and other material can be piled is required in working the nursery. 

 It is a mistake, therefore, to make the roads narrow. Both seed- 

 beds and transplant beds when not bordering on roads should 

 be surrounded by temporary paths, from l to 2 feet wide. Seed- 

 beds are usually 4 feet wide and from 12 feet long to the entire 

 length of the compartment. Transplant beds are 4 or 6 feet 

 wide or the entire width of the compartment. They are usually 

 as long as the compartment. The seedbeds should not, as a rule, 

 be continued year after year in the same compartment, and the 

 transplant beds in other compartments. A rotation permits of 

 more economical methods of manuring and the improvement of 

 the soil by growing soiling crops.
