p The Artificial Fertilisation of Vanilla Plani- 
folia. — The fertilisation of the Vanilla, says a corres- 
pondent in the Deutsche Gartner Zeitung for May 20, 
like that of other Orchids, cannot be left to Nature 
if fruit is to be obtained. The chief poi it is abundant 
ventilation in favourable weather. The pollination 
should be undertaken daily with newly opened . blos- 
soms about noon. As the pollen of the Vanilla is not 
powdery but sticky, the operation is not performed 
with a camel-hair pencil but with a wooden spaaila 
by means of which the pollen mas3 is lifted and 
smeared on the stigma. In this simple manner a 
plant, certainly a large one, in the Jardin des 
Plantes in Pads set about 100 fruits.— Gardenzrs' 
Chronicle. 
COFFEB CULTURE IN HONDURAS. 
The United States C'msul at Tegucigalpa i 1 a 
recent report to his Government, deals with the 
subject of the prospects of coffee culture in Hon- 
duras, and states: — 
'■ The cultivation of the coffee plant is yet in ita 
infancy in the Republic of Honduras. While there 
are nuni*rous so-called plantations of coffee, they 
are small and indifferently cured for, and, conse- 
quently, the production ia far from being np to the 
proper standard. 
" The foil, climate, and conditions in Honduras are 
equal in evei v reject to those of Guatemala. Nic- 
aragua, or Costa Rica, where the coffee industry hag 
already reached large proportions. The only draw- 
back in Honduras is lack of means of transportation 
and facilities for shipment to the coast. At present, 
there is practica'ly no exportation of coffee from 
Honduras, the product of the plantations being readily 
sold at home. I have known the price of coffee, even 
in time of peace, to reach the sum of 40 cents (gold; 
per pound, and in time of war, as much a-, 75 cents 
notwithstanding the splendid adaptation of the country 
to its production. 
"The Honduranean coffee is equal in every respcet 
to the Mexican, Guatemala or Costa Rican product, 
and is well-known to be of a superior quality, com- 
manding a price in the great markets of from 20 to 
25 cents per pound. 
" In the Republic of Honduras land can be had 
in either cf three ways— by direct concession from 
the Government or municipalities, by preemption 
under the agricultural law, or by direct purchase from 
individual-. In the first two ways, the lands will 
cost nothing or a nominal price ; in the latter, the 
lands will cost from 5 dols. to 10 dole, per acre. 
" A new plantation of coffee will commence to 
produce a profit by the end of the fourth year after 
planting, and after the seventh year a profit of from 
100 to 300 per cent, on the capital invested may be 
expected. The average cost of the production of 
conee, after the plantation is well started and five 
years old, will not exceed 7 cents per pound. 
" The preparation of the laud for a coffee plantation 
will consists only of clearing it off well and keeping it 
clean. The young trees are to be secured from a nur- 
sery, and cost from 10 dols. to 20 dols. per thousand. 
Nurseries, of course, are maintained on every planta- 
tion. The young tree is planted from 12 to 15 feet 
apart, in regular rows, like an orchard in the Un ted 
States, and the holes are dug about 1 foot square 
an! 15 inches deep. 
" The following extract is taken from the Two 
Republics of Mexico: All expenses of cost and plant- 
ing 1,000 trees are estimated at 100 d-ds. ; their 
keeping and attendance during the three following 
years or until they reach the bearing age, at from 
8) dol3. to 100 dols. per 1,000 trees. During the third 
year the plantation produces sufficient coffee to pay 
expenses. The outlay for every 100 lb. of coffee 
prep<red ready for market does not exceed 7 dols. 
as a maximum price, the market price of which is, 
at the present time, 20 dols. to 22 dols. per ino lb. 
The value of coffee plantations in full bearing is 
calculated at the rate of i dol. per grown tree, a 
single acre producing from 400 to 500 trees, which 
price only serves as a basis of purchase, at it includes 
besides the land and buildings, cattle, implements, 
and machinery. Much of the labo ir required for the 
cn'tivation and preparation of coffee is performed hy 
women and children, which largely increases the 
labour supply and reduces the cost, the average being 
30 cents per day. The season for planting commences 
in April and ends in November, but plants raised 
from seed require eight months to mature before they 
are ready for transplanting to the field in which they 
are finally to gruw. The altitude best suited for 
coffee culture is from 1,000 to 4,000 fee: above sea 
level, that is, up to what is termed the frost line. 
If the soil be rich and deep, 500 trees to the acre 
is a sufficient number. Results have been found 
more satisfactory with this number than with a greater 
or les3 number of trees per aire. The coffee districts
