1 The first figure of each pair indicates the number of years that stock is left in seed beds; the second 

 figure, the number of years that it remains in transplant beds. 



More than one class of stock of the same species is often proonceo 

 at a nursery, partly because the best class of stock has not been fully 

 determined, and partly because of the different conditions met in 

 planting operations. One nursery may supply stock for planting on 

 several varieties of sites on each of which a certain class of stock 

 may be most suitable. 



In transplanting at Forest Service nurseries spacings not greater 

 than li inches in the rows and 6 inches between the rows are the rule. 

 This allows ample room for root development and for cultivation by 

 hand cultivators. Though closer spacings than this are practiced 

 successfully at some of these nurseries, they are generally considered 

 inadvisable because the roots become intertwined and may be rather 

 badly damaged when the plants are dug up. The common error is 

 to space plants more widely than is necessary. No harm is done the 

 plants by this practice, but it involves the preparation of a larger 

 transplant area, digging and filling of more trenches, setting of more 

 lines, watering and weeding of a larger area, a more extensive water- 

 ing system, and, in. short, a great deal more work and expense than is
