For the fine se specimens, such as larch and 



spruce, spring sowing is entirely satisfactory, and we have 



i 

 had no trouble with see 7 holding over for a year, The 



sowing, however, should "be done early, provided the ground 

 is dry enough to work well, usu "bout the letter part 

 of Vpril. This applies to ell species for spring sowing. 



Yellow pine has heen sown in the spring, hut 

 this seed is showing r tendency to partly hold over its 

 germination until the last month or two of the growing 

 season. This late geimlnatlou in transplant stock is not 

 noticeable, although it may hrve its ill effect in winter 

 killing or the shock sustained "by transplanting, hut In 

 raising 2-0 stools, the seedlings of fell germination are 

 so inferior that it is necessary to cmll them out when 

 the stock is t ken u ^out 25- of the 2-0 yellow pine 

 stock taken UP this fall was discarded for this reason.
