EUCALYPTUS TREES. 65 
According to this calculation we could raise from one 
pound of seeds of the Blue Gum-tree one hundred and 
sixty-one thousand seven hundred and ninety-two 
plants. Let us suppose, for argument’s sake, that only 
half the seeds of such grew, the number of seedlings 
would be enormous; and even if only the seedlings 
of one quarter of the seeds of one pound finally were 
established, they would suffice, in the instance of the 
Blue Gum-tree, to cover four hundred and four acres, 
assuming that we planted at the rate of one hundred 
trees to the acre (allowing for thinning out). The fol- 
lowing notes, for comparison, may be of interest:

It seems marvellous that trees of such colossal di- 
mensions, counting among the most gigantic of the 
globe, should arise from a seed-grain so extremely 
minute, 
The exportation of Eucalyptus-seeds has already as- 
sumed some magnitude. Our monthly mails conveyed 
occasionally quantities to the value of over £100 ; the 
total export during the past twelve years must have 
reached several or, perhaps, many thousand pounds 
sterling. For the initiation of this new resource, by 
his extensive correspondence abroad, the writer can 
lay much claim; and he believes that almost any 
quantity of Eucalyptus-seeds could be sold in markets
