INDIARUBBER FROM EUPHORBIA. 
Major C. Giberne writing to the Standard sa.ya : — 
"Will you allow me to draw attentioti to the 
enormous quantity of Indiarubber locked up in 
the jungles of India in the various .species of 
JSupkorbia or " milk-bush,'' with which it is in 
parts so thickly studded ? 
'' Many years ago when in India I ordered a box 
of chemicals from England, and in the course of 
some e.'cperiements I made, I added a little nitric 
acid to the strong alkaline milk juice of Euphorbia 
tircualli, and to my surprise not; only neutraUied 
the alkali, but left floating on the surface a piece 
of Indiarubber. There is a considerable quantity 
oi E. ifVitCif/// growing ill Guzerat and especially 
in the neighbourhood of Bombay, but the supply is 
limited. On the other hand there are other species 
of milk-bush such as E. antiqurium and 
E. neriifolia, the supplies of which, should they 
be found efficacious, are inexhaustible. 
" I should strongly recommend that a trial be 
made of all these different species as to the qu;xlity 
of the Indiarubber they generally produce. 
Probably also a cheaper acid, such as hydrochloric, 
would prove efficacious as nitric acid. The milk 
could easily be extracted from the milk-bush by 
means of a common native sugar-cane pre.ss. The 
only question then would be whether the acid should 
be brought to the milk or the milk to the acid, 
and, in the latter case, whether it should be sent 
in the form of n fluid or be previously dried in the 
sun and e.^ported to England in the form of the 
gum known in commerce us Euphorbium." 
E. tiru"alli, E- antiquirum, and E. neriifolia 
are also well-known in Ceylon, and are familiar 
as " nawa-handi," "patuk" and "daluk" res- 
pectively. It remains to be proved, however, tliat 
the latex from these plaut.s is capable of yielding 
commercial rubber. Dr. Watt mentions the fact 
that many Eitphorbiao yield a gum or gutta- 
percha-like substance, but does not say anything 
ot as its ecoQomic value. 
GENERAL ITEMS. 
In a recommendation by Dr. W. Schlich, C.i.e., 
Principal Professor of Forestry at Cooper's Hill, 
which has just been circulated by the Government 
of India, that eminent authority on Forestry 
refers to a visit paid by him with his students to 
Vieraheim in Hesse-Darmstadt, ivhere they saw 
the regeneration of oak and Scotch pine in 
combination with the rearing ot held crops, which 
has been carried on in these forests during the 
last 80 years with remarkable success. He 
recommends this as an object lesson to Indian 
Foresters, particularly to those in Burmah, where 
teak cultivation under somewhat similar con- 
ditions is carried ou. 
A Frenchman (Jlons- Cossins) is said to have 
invented and patented a new process for sterilising 
all fermenting liquids. He plicfvs the liquid to 
be operated on in a closed vessel, and subjects 
it to a stream of oxygen proportionate to the 
quantity of fluid. Milk can thus be kept for 
any length of time after the steriling process. 
To make champagne milk, whicli also keeps any 
length of time, and is a most delicious and re- 
fresliing drink, sugar and an aromatic essence 
are added to thi; milk, which also receives a 
quantity of carbonic acid gas in a closed vessel, 
Not many people are aware that the onion 
contains a principle which acts ou the nerves in 
a manner similar to the action of opium. 
Unfortunately, the persistent odour of tlie vege- 
table makes seii^itive persons disinclined to use 
them, at all events in a raw state. Now, an 
onion taken at night, is one of the best sleep- 
inducers- The element above mentioned has 
tlio effect of calming the nerves, and consequently 
of putting the brain to rest.

Nursery, Cairns, sees uo reason why Cacao should
