TH£ TROPICAL AGRICULTURIST. 
[Februry i t 1889. 
I have seen was on Cinchona saccirubra where the 
coffee had been cut out. We have some patches of 
coffee that had it badly in 1887 ; got clear of it in 
the N.-E. monsoon and were scarcely touched 
past season ; but as a rule it has stuck most 
tenacior4y to trees once affected until many are 
killed ( c left in a hopeless state. As to what I 
think of it now : from former experience, I would 
rather not risk an opinion; but certainly at 
present there seems a prospect of its leaving us, 
that it has exhausted its fecundity and run its 
course, or from some natural cause got so weakened 
as to be comparatively harmless. Would that 
some scientist could till us if its generations are 
nearly run out, with little chance of new ones ; 
but I fear they are hermaphrodite. I am much 
pleased however to see that such an authority 
as Dr. Trimen has hopes that the bug may have 
nearly run its course, as, should it leave the 
coffee now, it will be a fine thing for those who 
have retained the old King ; he will be well 
worth all the care we can bestow on him. Some 
have the idea that manuring is only fostering 
and keeping on the bug, and I don't mean to 
say it will stop it, but I find, although some 
of our best coffee has been badly attacked, what 
has been lately manured has withstood it better 
and throws off the effect sooner than what is 
unmanured. Another thing is attention to pruning 
and handling, free air through the branches, and 
all suckers and small centre shoots carefully re- 
moved, as these are usually the favourite food of 
the bug. From the effects of leaf disease and bug 
the sap connection between root and branch has 
been so much weakened and intercepted that many 
roots have died, and this accounts in great 
measure for so many primaries and branches dying 
back, but should bug stop its course and we get 
some healthy foliage, the trees would soon recover 
their vigour. Although our average is much reduced 
we have still got coffee bearing its 7 cwt. per acre 
and looking as well as ever. Let us hope we are 
near the end of this dire scourge, and that we shall 
see a considerable remnant left flourishing to cheer 
the heart and gladden the eye of the worthy men 
who have done so much for Ceylon. 
We have had a most wonderful planting season, 
only 21 days since 12th Oct. no rain measured, 
but not all dry. Eainfall for past year to 31st Dec. 
100/13 inches and 13£ inches for Jan. to date. 
Heaviest rainfall 21st and 22nd Dec. mornings 7-13 
and 9*15 in. respectively. This was too much for 
our steep free hillsides, and caused much wash arid 
many slips. — Yours, J. BAGRA. 
HOPFBNBAU UND HOFFENBEHANDl/UNG. — By 0. FrU- 
wirth. Pages 184, figs. 32. Berlin, 18S8. Paul Parey. 
In response to a prize offer of 1,000 marks, by the 
editor of the Allegemeine Brauer und Hopfenzeitung of 
Niirnberg, Herr C. Fruwirth, an agriculturist of Vienna, 
has prepared a very thorough essay on the subject 
of hop culture and treatment, which has just been 
issued as a number of the " Thaer " library. It is 
a monograph upon the subject, practically and scien- 
tifically discussing tbe hep-plant in its botanical, 
agricu'tural, economical and commercial relations. Some 
interesting statements are made showing how varieties 
have been modified by change of environment. A 
comparison of the German, English and American 
products is presented. Detailed descriptions of the 
different methods of cultivation, fertilization, prun- 
ing, trellisin^, harvesting and curing are given with 
illustrations ; there is a short chapter on the chemistry 
of the hop t,nd its active principles ; and finally a 
sion of its commercial features. The whole makes 
a very complete and successful handbook which can- 
not f h i J to be a useful help to the practical hop-grower. 
Unfortunately for American readers it is published in 
Germ»n.— Agricultural Science.
