THE TROPICAL ACTRlCUI.TTJrJST. [March 2, 1903. 
engineers, ship building firms, and indeed steam 
nsers generally. Various forms of burners have 
been placed on the market, and though consider- 
able efficiency has resulted, there is no reason for 
believing that finality or anything approaching it 
has yet been reached. To obtain the fullesc ad- 
vantage which liquid fuel possesses over solid fuels 
it is important that the burner should provide 
means for the complete conibuEtion of the oil, and 
thus avoid the deposit of a solid residue. Mr. 
Kenny claims for his invention that it afi'ords a 
simple means for the more efficient and economi?,al 
combustion of liquid fuel for the production of 
steam, for smelting and for other pu>"poses, and 
that it overcomes many of the objections attached 
to oil fuel burners as liitherto constructed. The 
apparatus consists of a easing fitted with an oil 
inlet and having two internal diameters with two 
nozzless attached, one being fitted within the 
other and forming with the outer casing passages 
for air, steam, and oil. If necessary it may be 
worked by air pressure instead of steam, though 
the latter is stated to be the more eeononiiial. 
We understand that Mr H Cowdeil, of the Crad- 
ley Heath Boiler Works, Staffordshire, is the En- 
glish agent for this burner, and that applications 
liave been received from several important firms 
for permission to adopt it. Under these circum- 
stances there is not the least doubt that the burner 
will receive the fullest trial, and we trust these 
trials will bear out the satisfactory results whicli 
were obtained during the experiments carried out 
in this Settlement. — S F Press, Jan 21. 
THE ANOPHELES MOSQUITO. 
A Renter telegram from Liverpool, dated 
January 9, says f — " A letter has been received by 
the Hon. secretary of the Liverpool School of 
Tropical Medicine from the leader of the Sierra 
Leone expedition of the school. Dr. Logan Taylor 
(who has been sent on an expedition to the Gold 
Coast by the school), with reference to the progress 
of the expedition in Sierra Leone. Dr. Logan 
Taylor says : — ' I am getting a report ready for the 
school about the Sierra Leone work and will let 
you have it soon. We had to stop most of the 
men at the end of August, only keeping on the 
oiling gang after that. I am well pleased with the 
work this gang has been doing during my absence, 
as when I went round to inspect their work I found 
both in untouched and drained streets a very 
noticeable absence of anopheles larvaj in places 
where we used to be able to get any number. This 
is due, of course, to their not being able to breed 
owing to the pools being either swept out or oiled 
regularly. The result of this is, that, compared 
with the corresponding time last year, in some of 
the notoriously bad streets, where in a single house 
we could find as many as six, seven, or a dozen 
anopheles mosquitoes in the early morning, this 
year with great difficulty, after searching house 
after house, we could get one, or perhaps two, adult 
insects. J[ can keep on an oiling gang of men and 
the headman Shaw until the end of February or so, 
by which time I should be free of the Gold Coast, 
and am leaving 11 men to peg away at Grassfields 
District until I return to Freetown. An extra 
£500 has been put down in next year's estimates 
for continuing drainage work. The engineers are 
working at the hill railway, and also at the new 
waterworks. I may say that since the men of the 
Liverpool School expedition stopped clearing up 
yards and emptying out the water containing culex 
larvaj no one else has taken up the work, and these 
insects are getting bad again ; in fact, the rubbish 
is beginning to accunnilate in the yards just as 
before, and several of the Europeans were com- 
plaining to me of being much annoyed by culex and 
stegomyia. This means that, unless the Govern- 
ment or the school will keep on the work, the 
money the school has spent on it will be almost 
thrown away. My destination now is Cape Coast, 
where I am to go and take charge of the sanitary 
work of the town and see that my former recom- 
mendations are carried out. The people at Accra 
have been very kind, and the principal medical 
officer and the medical depirtment are doing 
everything to assist me,' ' — London Times,

RUBBEB PLANTING IN TENASSERIM. 
The Rubber Planting experiments in the Te- 
nasserim division by the Forest Department have 
been continued on an extended scale, 772 acres of 
land having bean cleared and 663 planted vvith 
Hevea during the past year. The area of the ex- 
perimental garden has been extended by some 42 
acres, and the Kambe rubber plantation, Rangoon, 
has been taken over by the Forest Department 
from the Cantonment Committee. — Madras Mail,

"DE INDISOHE MERCUUR." 
This excellent and ably edited agricultural 
and' commercial weekly, published by Mr. 
J. H. de Bussy of Amsterdam, has attained 
its twenty-fifth birthday, which has been 
commemorated by the issue of a special 
number, with an artistic cover, containing 
a number of contributions by well-known 
Dutch writers on agriculture with facsimiles 
of their signatures, a history of the " In- 
dische Mercuur " by Mr. de Bussy, &c., &c., 
and numerous illustrations. Among the 
papers is a reprint of the in memoriam 
notice, by Mr. F. W. Van Eeden, of Mr. 
J. C. B. Moens, formerly the director of 
the Government cinchona plantations in 
Java, who died in 188R. and who once paid 
a visit to Ceylon. We congratulate our 
contemporary on having reached the quarter- 
century of its existence, and wish the 
" Indische Mercuur" a long career of use- 
fulness.
