*If the wild tree always seeks the shade of trees of greater 
growth iu the natural forests, it is because, by the help of these, 
its sap remains in the state imposed by nature as a condition of its 
proper growth and production. It is not the desire here 
: o 
leaves do not resist the sun, nor do they, by the nature of their 
surface, oppose evaporation. It is clear that without shade there 
is an evaporation which must exercise a harmful infiuence upon 
the production of the milk of the tree. It should also not be lost 
ue of that on the Pacific Coast we have a dry season for six 
onsecutive months, very prejudicial to plantations in the sun. 
Allow the rubber tree a high and well-distributed shade, withont 
undergrowth or brush, and tbe result will be healthy and robust

conduct the Mitis of iila alae "with that of 
rubber, utilizing the trees for shade. 
“Advocating the planting in the shade is equivalent, in a 
untry like een still possessing so much virgin forest, to 
sete ing in the woods. There are thousands of acres of land 
where it would to autioloht = clear the forest (cutting down part 
and removing the low branches and undergrowth) in order to 
obtain ground sufficiently shaded and with the necessary ventila- 
tion, the latter a condition of the greatest importance. The trees 
and undergrowth cut down could be spread ae! the ground to 
prevent the growth of weeds, as well as to serve as manure. 
pla pos the rubber tree the ground should be ‘perfectly cleaned 
for a circle at least a yard in diameter and the tree placed in the

trees are taken out with great care (it is best if the FAX adheres 
to the roots) and transplanted. 
* The least distance at which rubber trees should be set out is 
covering the und as has previously been explained. In the 
third and inn years two to Hind cleanings per year should be 
made ; and from the fifth year, one cleaning annually will suffice 
until the growth of the tree impedes the further wh m of 
weeds. Before beginning to exploit, the trunk of the tree should 
measure at least 12 inches in diamete ter, an and eX e + 15 yards in 
height, for which from 9 to 10 years is n
