THE TROPICAL AGRICULTURIST. [Nov. 1, 1900. 
with great vigor ; and from the fact that I am now 
gathering fruit from trees not yet three years old, 
I feel confident in recommending the culture of 
Lemons to you as likely to add at no distant date, 
a valuable quota to our fruit exports. Yet another 
variety of valuable citrus family jis the Pomelo or 
Grape Frait. Americans have developed a gr«»t 
taste for this fruit, and when it gets better known 
in Europe it may have a great future, and be a 
source of wealth to this community; for no where 
else can better Grape SFruit be grown ; and the 
rapidity with which this fruit grows and begins 
to bear is very encouraging. Some of our native 
varieties are excellent, whilst there are a great 
many bad and rubbishy hybrids that it will be 
useless to waste time and space to cultivate. Of 
the imported varieties Royal Pomelo, Triumph 
"Walters and March Seedless are the best ; whilst of 
natives, the Wilton and the Windsor are the best 
that can be procured, alchongh there are no doubt, 
several other good varieties in the country. But 
whatever you do, select a variety of proved good 
quality. It will always pay to grow the best. 
The cultivation and propagation are the same as for 
oranges. The greatest troubles that the orange 
grower has to contend with are insect pests and 
disease. But the grove owner should bear in mind 
that his best weapon against these enemies is careful 
and constant good cultivation. Bear in mind always 
that insects and disease will always attack the 
sickly and weakly plants : whilst the well cultivated, 
vigorous growing plant will have within itself power 
to resist and throw off the attacks of its enemies, the 
weakly illcultivated plant will easily succumb. It 
pays therefore to keep out weeds and ply Jthe cultiva- 
tor regularly through your groves, if for no other 
reason than to keep your plants in vigorous growth, 
BO that they may be able to resist the encroach- 
ments of their natural enemies. Time will not per- 
mit me to give you an elaborate lis of Latin and 
Greek names of the insects that are enemies to 
citrus cultivation, but the coloured plate which I 
have here will show you which are your friends 
and which are your enemies, for by that wonderful 
provision of a beneficial providence one set of insects 
prey on the other, so as to preserve the balance of 
• nature. There is however one active little enemy to 
combat against ; an enemy whose name is legion, and 
wha if allowed to follow out its own plans will nip off 
the embryo leaves of the plants the moment they 
appear above the ground. I refer to those very indus- 
trious creatures whom the primers hold up to us as 
an example to emulate, but it could be wished that 
their proverbial industry was more tempered with 
iudement in consideration for struggling humanity. 
I mean ants, of course. They evidently .regard your 
citrus leaves as special dainties', and must be taught 
to keep their distance. An application of air slaked 
lime or hard wood ashes on the seedling bea and a 
Dlanting of strong solution of bitterwood on the larger 
trees will damp their ardour. Another enemy is the 
rust 'mite which attacks and destroys the fruit and 
exhausts the oil cells and renders the orange pnmar- 
ketable Here is an orange attacked therewith. A 
solution of one pound whale oil soap to five gallons 
of water, and applied with a brush to the afiected 
rarts of a tree just before thvi blooming seasen, is an 
effective remedy. Sulpher is also a good thing to 
spray with for this insect. The scale insect is another 
dangerous enemy, and I have here a limb with some 
scale on it. The Laybird is its greatest enemy, 
ijut if no Ladybirds are in your grove a solution ot 
lime kerosene oil and water is a very effective 
remedy And here is one of the most deadly enemies 
to citrus cultivation, the beetle, we know aa Pidler. 
It feeds in the leaves of the trees, then deposits its 
ecea at the root of the trees, and in time produces 
the larvae which feeds on the bark of the roots, and 
as the roots are barked the whole tree ere long |feela 
the loss of its necessary nutrition, and twig after 
twig, branch after branch, dies back, often puzzling the 
owner to determine the trouble. So soon as you 
notice the dying back begin, search carefully rotind 
the root of the tree, and you will find numbers of 
larvae, very like " Mackaka " worm but smaller with 
a hard black pointed beak. Deal out death to every 
one and apply about half lb. of sulphate of ammonia 
and this will drive them away. Prune the trees, 
carefully back, removing all dead or dying branches. 
Prone tbe roots also cutting away the barked roots 
to give those left alive a chance , to < recover vigour. 
Wage perpetual war against Mr. Fidler wherever 
you see him — let death be hi» certain lot and thus 
keep down a dangerous pest.. — Journal of the Jamaica

TEA CIRCULAR ON TEA REFUSE 
TEA WASTE AND DAMAGED 
TEA FROM MESSRS. BARLOW 
AND CO. 37, STRAND, 
CALCUTTA. 
Dear Sirs, — A considerable quantity of the above 
occurs on all factories from various causes, and is 
swept out of the tea house and thrown among the 
bushes or on the ash-heap. Hitherto there has been 
nothing else to do with it. We have, however, lately 
learned that, though useless for human consumption, 
it has a certain value for other purposes. We recom- 
mend you, therefore, to have all the following collected 
and put into goodolA rice bags and sent down to us in 
these bags, when we will dispose of it for you to the 
best advantage- 
yea Flvff. — This is fairly abundant in every part of the 
sifting room, and should be regularly cleared off the 
walls, roofs, beams, etc. 
Tea Refuse. — This includes all pickings during gift- 
ing. Tea blown into odd corners from the dryers, 
teas accidentally left in the corners or under bins, 
etc., etc., till soft and unfit for mixing with ssuad 
and marketable teas. 
Tea Sweepings. — This includes all tea house sweep- 
ings after the work is done, freed of dirt and 
dusty earth or sand as far as possible. 
Damarjed Tt". — Any tea rendered unfit for mixing 
with sound and marketable tea, from any cause 
whatever, such as water, fire, or smoke, should be 
collected and put separately into bags. Any sank 
tea, or tea otherwise damaged by water, should be re- 
dried as soon as possible. 
It is however, to be practically noted that any such 
damaged tea is to be kept entirely separate, and not 
mixed with the above, till you have received in- 
structions as to what is to be done with it. 
Such tea should not be thrown away, as it is of 
some value. 
Tea Dust. — ^Not fit for human consumption on ac- 
count of the earthy dust mixed with it, should be sent 
down in bags. 
We believe it is the practice with some concerns 
to sell the above refuse locally. This is a most 
objectionable practice, as it frequently gets into tbe 
bauds of natives in Calcutta, and possibly out of 
India, and is sold as tea much to the detriment of the 
reputation of Indian teas. The practice is, therefore, 
most harmful, apart from all sanitary considerations. 
We trust you will do your best to stop such traffic. 
We give our absolute gurantee that none of the, 
supplies of the above sent to us will be used for 
human consumption in any way whatever. 
N.B. — Tea stalks by themselves are useless Bad 
should not be sent down, as we are advised at presentf 
but any normal mixture of stalks with the above re- 
fuse will not effect the sale. 
Please advise us about what quantity of the above 
you will have available from now to the end of the 
present season, Ou hearing from you, instrnctioni 
will be sent to you for forwarding it to Calcutta, 
We are, Dear Sirs, yours faithfully. Per Pro BarlolT
