Experiment 2/07 0. — Seeds sown in nursery, October, 
1907. Planted out in April, 1908. Average height, 5 feet 
9 inches; average girth, 1}| inches. 
Experiment 2/07 D. — ’Seeds sown in nursery, October, 
1907. Planted out in November, 1908. Not measured. 
Stumps cut down to 18 inches. 
Experiment 3/07. — Close planting. This plot shows 
very fine progress as a whole. The plants have not yet 
become crowded enough to have any bad effect on their 
growth. A large number of the plants have shot ahead of 
their neighbours, but whether they Avill maintain this lead, 
and kill out the weaker plants, remains to be seen. The 
average height is 10 feet 61 inches; average girth, 2 T 7 ^ 
inches. 
Purple Manicoba Rubber (Manihot sp.). — The plot of 
tins plant, put out in November, 1907, has made good 
growth during the year. 
The plants have now grown into strong bushes, averag- 
ing 12 feet 2-1 inches in height, the stem measuring 5f inches 
at 3 feet from the ground. 
Jiquie Rubber (Manihot dichotoina). — Seeds of this 
rubber, recently discovered in Brazil, were received from 
the Royal Botanic Gardens, Kew, in October, and sown both 
at stake (U acres) and in nursery beds. 
The seeds germinated freely and the plants appear to 
be very similar to the' Purple Manicoba rubber received last 
year. 
Romanso Rubber (Manihot piaiihyensis ). — Seeds of 
this species, also from Brazil, and discovered at the same 
time as the above, were received from the Royal Botanic 
Gardens, Kew. They were sown under conditions similar 
to the “Jiquie” variety, but many of the seed failed to 
germinate. I have, however', got about 50 plants which 
will be put out in this year. 
The young seedlings of this rubber are thicker and 
more sappy in appearance than those of M. dichotoma. 
These new Manicoba rubbers "belonging to the same 
family as the Ceara rubber (Manihot Glaziovii) but are said 
to be much superior to the latter species in every way. 
They grow naturally in drier and less fertile land than the 
Para rubber (II eve a braziliensis). 
Ram bong (Ficus elastica ). — The two acres of this rub- 
ber put out in 1907 are now well established and the plants 
have begun to grow freely, about a dozen vacancies were 
supplied.
