» 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 proaucea 
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 1J 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
