In 1839 there were exported 46,781,729 kilogrammes, valued at 48 million florins.  Eight years labor, 1833 to 1841, brought its produce of coffee from 12 million kilogrammes annually, up to 55 millions.

In 1846, the exports were 916,876 piculs, but, in 1850 they were only 14,801 piculs.  The total coffee crop of Java was in 1850, 1,280,702 lbs.; in 1851, 1,436,171 lbs.; in 1852, 1,229,349 lbs.

The comparative result of this table shows—­1st.  That, in the year 1841, coffee had been gathered from 20,000,000 more trees than the number in 1840, and that the crop had increased by 171,000 piculs.

2nd.  That, in the month of March, 1842, there were above 7 millions less of coffee trees than in 1840.  This diminution is merely nominal, seeing that these trees have served to replace those which by their small produce have to be suppressed in the lowlands of the residency of Baylen.  On the contrary, the increase of trees, planted from 1839 to 1840, amount to very nearly the same number, of 7 millions.

3rd.  That, in the season of 1842, there was planted nearly 20 millions of plants; of which 12 millions are to serve to replace the old trees, and 8 millions are destined to extend this culture.  It is calculated that this island will very soon be in a condition to produce a million of piculs or 125 millions more of Dutch pounds of coffee.  Previous to 1830, Java scarcely exported as much as 40 millions of pounds.

Cultivation and Preparation of Coffee in Java.—­For the following valuable details I am indebted to M. de Munnick, the inspector of the agricultural department, Batavia, as contributed to my “Colonial Magazine” (vol. xi. p. 46).

Soil and Situation.—­Elevated lands are found to be those best suited for the growth of coffee in Java.  Land situated between 1,000 and 4,000 feet above the level of the sea may be generally said to be adapted to the cultivation of coffee.  It must not be taken for granted that all ground of less elevation is unsuited.  Suitable ground is to be found lower down, but the cultivation on it is more difficult; the tree gives less fruit, and the plant is less durable.  Valleys lying between high mountains are more especially fit for coffee plantations, because the soil which is washed down from the heights affords fresh food continually to the lowlands; the valleys themselves are moist, since the hills surrounding them attract the rain; and they are shut out from severe winds by the same protecting enclosure.  The soils best suited to the successful growth of coffee may be classed as follows:—­
