PRECOCITY IN RUBBER TREES. 
Dear Mr. Ridley, 
With reference to your article in the August num- 
ber of the Bulletin on “ Precocity of Rubber Trees” 
it may interest you to learn that on 23rd Dec. 1908 we 
successfully raised seedlings from seed obtained from a 
Para tree planted as a stump in June 1906 : the fruit set in 
28 months, and the resultant seedlings sprouted 30 months, 
from date of planting out the stumpiW 
Over fifty trees flowered within 28 months of planting 
out the stumps and four of these set fruit within 30 months. 
In all cases stumps were not more than 12 months old 
when planted out. 
As to the undesirability of such “ precocity ” I would 
quote the opinion of Sir W. T. Tliiselton-Dver of Kew 
Gardens “ I am not aware of any grounds theoretical or” 
“practical for thinking that the age of the seed parent” 
“makes any difference to the offspring in the case of” 
“Para rubber or any other tree. The first Para plants” 
“were senr from New to the Straits Settlements in 1876:” 
“it may be presumed therefore that all the trees now” 
‘ ‘ growing there are the progeny of comparatively young” 
“parents. ” 
Yours faithfully, 
Prank E. Lease. 
Note on above. Mr. Lease’s trees though very pre- 
cocious are not much more so than the ones mentioned in 
the paper referred to as their age works out to 40 months 
from seed i.e. 3 years 4 months. The objection to precocity 
is not based on any supposed weakness of the offspring of 
the trees, about which as Sir 'William-Thiselton Dyer says 
we have no evidence but upon its action on the tree itself, 
i.e. whether or no such trees are short lived'. In the case 
of Nutmegs fruiting in three years instead of the normal 
seven, it is strongly believed and there is some evidence for 
it that such trees die out more quickly than the normal ones. 
There is no advantage to be gained by the rubber planter 
in his trees fruiting early, but there is a great advantage 
in their being large and stout trees early. In the early 
fruiting trees I have seen and mentioned the stems were
