where the dead woods ends, the other side is quite healthy and 
latex flows on being cut, one of the branches above on that side is 
putting out leaves but the others still show no signs ol life. I could 
not reach up to try them with a knife. 
The second tree is sprouting about 5 or 6 ft. from the ground 
where it branched before, there is a good tuft ol foliage but the old 
branches seem dead, I could not reach them to try them with a 
knife or break one of them off, the hark appears to be cracked and 
dead on them. 
The third tree is sprouting about 3 ft. from tbs ground on the 
trunk, above that the stem is quite dead, l cut into it all round and 
found no sign of vitality. 
The trees are of no value to the owner of the plantation, being 
the only three on it, and have not had any attention paid to them 
since they were first burnt or scorched, they are sprouting again 
simply from their own vitality. 
R. SCOT T. 
Mr. Scott’s note Oil the recovery of Para rubber trees gives 
another illustration of the vitality of the plant. It will be inteiest- 
ing to see if the trees completely recover and develop into strong 
plants again. The danger . to a tree burnt on one side badly is 
from the attacks of fungi on the dead portion which may be too 
extensive for the young bark to cover, rot once getting in to the 
heart of the tree is sooner or later fatal, though the tree continues 
to give latex abundantly from the uninjured portion, or as it ap- 
pears even more abundantly than in the case ol a thoroughly sound 
tree. A good deal depends on the age or rather size ot the tree 
damaged, younger trees would stand tire probably bettei than old 
ones, ‘and would repair better. I have seen an old stump about 7 
feet tall, and about a foot through which constantly puts fresh 
shoots, but these come to nothing, the decay of the inteiior of the 
trunk goes on downwards slowly, and the young shoots make no 
growth. The injury is too extensive to be covered with fresh bark. 
Several trees of considerable size were accidentally scorched at the 
base by a fire. One died soon from the attacks of fungi, perhaps 
helped on by boring beetles. I he fungi spread to the loots and 
attacked the trees on either side two or three of which died in 
about a year or two. — Editor. 
CASTILLOA RETURNS. 
In the Bulletin of the Para Museum, Dr. jACOUES HUBER (Vol. 
Ill Feb. P. 84) gives an account of the yield of some trees of Cau- 
cho (Castilloa elastica). 
He says a grown up tree yields as a rule one vessel full of latex 
which contains 14 gallons.' This quantity corresponds with 20 
kilogramts of Caucho in slabs and as one slab weighs generally 
about 60 kilos or one man’s load it takes 3 trees to make a slab.
