PLANTING. 109 



As to the actual quantity of seed to be sown, views 

 differ so considerably, that it is not possible to give 

 average data. In a nursery at Inverness,' 5 ''' the 

 following quantities of good clean seed are sown per 

 100 square feet of seed-bed : 



Scotch Pine . = -6 pound. 



Spruce . . = .'6 



Austrian Pine . = '8 ,, 



Larch . . . = 1-0 



Biermans, a well-known German sylviculturist, sows 

 about four times the above quantity of seed. Messrs. 

 Howden & Co. consider it a good full crop if one pound 

 of good Scotch Pine seed produces 15,000 seedlings. 

 Biermans expects only 7000. 



Gayer gives the following average quantities of seed 

 to be sown in drills per 100 square feet of seed-bed : 



Oak and Sweet Chestnut -05 bushel (at 8 gallons). 



Beech . . = '13 



Ash and Maple . . = '3 pound. 



Elm . . . = -23 



Hornbeam . . = *18 ,,
