COLLECTING AND HARVESTING TEEE SEEDS.

These figures must only be taken as approximate, the seed 

 of various trees of the same species seeming to vary in 

 number to the pound in a marked degree. The results of 

 careful analyses of one or two kinds may be cited as examples. 

 In one case the number of seeds in 1 Ib. weight of Scotch fir 

 was 69,600, while in another it had increased to 90,600 ; and 

 in the larch the numbers were 63,900 and 68,000. 



These differences are, however, readily explained by the 

 individual seeds being weightier in one case than in the 

 other, probably owing to the age and health of the tree from 

 which they were collected, the situation and exposure 

 to which it was subjected, etc. However, for all nursery 

 purposes the above figures may be accepted as a fair 

 standard.
