pine. With all pines the seeds must be kept dry during the winter. 

 The oil in them will preserve them so there is very little danger of 

 their losing the power of germination for several years if they are not 

 exposed to moisture. Sow the seeds broadcast in sandy beds in 

 spring. Seedlings can be set out in spring when two years old. 

 They are very sensitive to being transplanted so their roots should 

 be carefully protected. It grows where the soil is extremely poor, 

 but slowly. 



SPRUCE PINE, YELLOW PINE. 



Pinus mitis, Michx. 

 Pinus echinata, Mill. See Britton & Brown, Vol. I, p. 52. 



Leaves usually in pairs. The cones are somewhat longer than 

 those of the pitch pine but not so large in diameter, proportionally, 

 They mature in one season. Formerly there was considerable yel- 

 low pine in this State but it has become very scarce. . The tree 

 reaches a large size and its wood is valuable. It is not hard to raise 

 from seeds, which should be treated as those of the other pines. It 

 is a fairly rapid grower and is adapted to dry, sandy soil and to poor 

 slopes. 



The red or Norway pine (Pinus resinosa) may be propagated as 

 easily from seed as the other pines. 



RED SPRUCE.

A tree of the highest ridges and cool northern slopes. The cones 

 are small and unusually plentiful. They may be gathered any time 

 after October. By heating the cones some, the seeds will readily 

 fall from the scales. They should be sown in early spring in soil 

 somewhat sandy. Cover the seeds lightly and roll the beds. Shade 

 the seedlings well and do not let the beds become too dry. The 

 plants may be put in the plantation when two years old or they may 

 be transplanted to nursery rows and set out when four years old. 

 They have shallow roots and may be used on rocky slopes. In regu- 

 lar plantations three feet is the proper distance at which the plants 

 should stand from each other,
