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

 seedbeds; D, soiling crops. Area, 12 acres; annual capacity 1,000,000 white

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 1J 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.
