tree. We find trees that are not more than ten inches in cir- 
cumference that will give a profitable yield, while some six- 
teen-inch trees do not give a profitable yield. We find, too, 
that removing the bark all at once is apt to injure the tree, 
but we will probably try to find some way of removing all of 
the outside bark at once. This knife does very good work 
cutting through even the original tough bark as well as the 
new bark that might form. 
"We have over 1200 trees and I think it will work out to 
tap about nine times and then rest the tree for a week. 
"We cannot tap one tree one hundred times in a year unless 
we make our cuts wider than this. Of course, if we made our 
tappings twice as far apart, we would get twice as much rub- 
ber. We may find that it will be wiser in the long run to 
make our tappings farther apart. I do not think that we shall 
want to tap all the year around. The trees should be rested 
from the first of February until the first of May. It will 
probably be found wiser to tap the tree nine times and then 
rest it for three weeks and then make another tapping, in 
which case we remove one inch of the bark. By this scheme 
we make eight or ten cuts each side of the channel, and that 
makes sixteen or twenty cuts on the tree. Of course, the ex- 
pert will prick a great many more than he will pare. We 
select the more skillful ones for the tapping. We are not 
using any acid. We tried a scheme that I believe is being 
used in South Africa. We found the same difiiculty there 
that we found in trying to grow without paring. I am firmly 
convinced that more or less injury is done to the tree every 
time the bark is taken off. The scheme that we have now 
adopted avoids that difficulty.'' 
PAPER BY MB. L. F. TURXER. 
After the conclusion of the discussion following Air. An- 
derson's paper, Mr. L. F. Turner read an address on "Cul- 
tivation of Rubber Trees and Its Results." It was as follows : 
"I have been asked to prepare a paper on Cultivation and 
Soil Conditions. I presume that the request refers entirely 
to rubber culture, as it is to be read at a convention of rubber 
planters. 
"Several conditions are necessary for success, with rubber 
as with all other crops ; Ave must have soil to cultivate, and we 
must cultivate the soil ; to a reasonable extent at least. To 
this may be added that heat and moisture and proper climatic 
conditions are also essential. This much will be conceded by 
all, and then — each man has his own opinion of what culti- 
vation means. 
Different conditions require different methods of treatment ; 
each manager probably recognizes that the stirring of the soil
