Biermans, a well known German sylviculturist, sows about 

 four times the above quantity of seed. Messrs. Howden ct Co. 

 consider it a good full crop if one pound of good Scotch pine 

 seed produces 15,000 seedlings. Biermans expects only 7.000. 



Gayer gives the following average quantities of seed to be 

 sown in drills per 100 square feet of seed bed : — 



Broadcast sowing takes from twice to four times the quantity 

 of seed required for drill sowing ; hence Gayer's data for 

 conifers agree fairly well with those given l)y Messrs.

In some cases the seedlings are taken direct from the seed 

 bed to the forest ; in others they are transplanted once or 

 several times in tlie nursery before they are finally put out. 

 British foresters call the former " seedling plants," and the 

 latter " transplants." 



Seedling plants which are to go direct to the forest must be 

 grown roomy in the seed beds, so that they may develop 

 properly; plants which are to be pricked out in the nursery 

 may stand closer together in the seed beds. 



Pricked-out plants are generally placed in rows, called 

 " nursery lines." The soil devoted to them must be carefully
