RUBBER NOTES. 
Angola. 
From the district of Loanda there has been exported during the 
last 12 months for the first time one ton of plantation rubber. This 
is the product of the common Ceara species introduced into Angola 
some 18 years ago. The Panama and Para rubber trees planted 
during recent years are making satisfactory progress. The Manicoba 
Jequie have been cut for the first time in March last. The trees were 
then 2 years old, full of fruit and yielded an average of 35 grammes 
per tree. By many growers this species is considered inferior to the 
Ceara Manicoba which grow like weeds in the Coffee belt and is 
actually preferred to the Hevea Braziliensis which requires double 
the time to develop. Owing to the introduction on the market of 
a new knife for extracting the milk from the Manihot Glaziovii the 
planters have recently become enthusiastic. 
The percentage of scrap rubber is greatly diminished as the milk 
is diluted on the trunk with a simple alkaline solution which prevents 
rapid coagulation and permits the preparation of rubber in the form 
of transparent sheets having a high market value. 
All the rubber cultivators are comparatively poor Europeans. 
There are a few r planters who established new plantations exclusively 
of Ceara Manicoba.

[Evidently Angola is suited well for the Ceara rubbers and from 
what we know of the soil and climate this is what might be expected.] 
Uganda. 
The Para rubber trees in the Botanic Gardens continue to make 
most satisfactory growth and tapping experiments show that the 
prospect of Para rubber cultivation are most encouraging. The 
growth of Funtumia elastica trees is slow compared with that of Para. 
The results of an experimental tapping of a 6 V 2 years old tree show 
that they are not of a tappable size at this age. The Castilloa rubber 
tree grows well but it is very subject to the attacks of a borer 
(Inesida leprosa) w'hich does very great damage to the trees and 
accordingly it must be considered to be of very little importance 
to the Protectorate.” 
The Manihots all seem to do well here. Total number of plants 
distributed by the Botanic Gardens during the year was 160,679, 
The demand for Cocoa and Para rubber seeds greatly exceeded the 
suppbvand in addition to the plants and seeds distributed by the 
Botanic Gardens a large number of seeds were distributed at Kampala 
and on behalf of the planters. Large numbers of seeds chiefly of Para 
rubber were imported by the planters.
