Account of the State of the Cultivation of the Cinchona in Java in the Second Quarter of 1868. 
By C. Van G-orkom. 
During this quarter there were obtained about 1(3,666 plants of C. Calisaya (of which about 5000 were from Bolivian seeds) , 
13,845 C. succirubra (mostly from seeds from Ceylon), and 9840 C. Condaminea, so that at present the account of the plantations 
contains — 
C. Calisaya 
C. succirubra . 
C. Condaminea 
C. lancifolia 
C. micrantha . 
Total 566,993 Plants.

The state of the weather was less favourable for the youngest plantations ; the continuous drought must also have half- 
checked the extension of the plantations. On the other hand, the preparation of the woodland was greatly promoted, and in two 
months sufficient land will be got ready for the following year. Free day-labourers were paid for 11,160 days’ labour. The 
number of fully-engaged and more or less skilled workmen amounts to 120, of whom about one quarter are continuously employed 
in the nursery garden. 
The development of the plantations of 1866 and 1867 is very satisfactory. On the Tilu and Tankuban-Prahu Mountains it 
may be called unusually good; on the Malawar Mountains the gardens are rather behindhand. Without any particular reason 
being manifest, the leaves of the C. Calisaya pucker and dry up, and their power of life appears to slumber. In other establishments 
this has only exceptionally been the case. In 1866 a similar sickness showed itself in the former year s plantation; nevertheless 
the consequences were not serious, and this plantation has so far extended itself since, that in the year 18/1 some thousand 
kilogrammes of bark may be expected to be gathered therefrom, in order to bring these first proofs of the Java cultivation to 
market. It is to be hoped that some seasonable showers will bring the Malawar plantation again into its normal state. 
Many G. Condaminea plants already begin to blossom, and from single O. lancifolia plants we may expect fruit towards the 
end of this year. Seeds of the C. Calisaya were continuously gathered in still larger quantity, even under the plants which were 
produced in 1865 from American seeds. Some plants of the G. Calisaya vera are loaded with ripe fruit. Through the friendly 
and efficacious assistance of Dr. Thwaites, of Paradenia. (Ceylon), the stock of C. succirubra and C. Condaminea plants was largely 
increased. This help is very highly prized, and its continuance will be very welcome in future. The C. Calisaya seeds received 
from Bolivia have relatively produced bad results, for only 5000 seedlings were produced therefrom. 
Most of the raising-houses have required considerable repairs : two new contrivances were completed, and measures taken that 
the kinds of Cinchona which have not produced any seeds in Java should afford young plants with greater quickness. 
First, in September and October great numbers of seeds of the C. Calisaya will be sown, since further steps must be taken to 
protect the plantations against ruin in a rainy season, in order to have from nine to twelve months after the sowing of the 
seed, the plants strong enough to plant out in the open ground. 
Seeds of the Cinchona have been continuously desired by private individuals, but no results have yet shown a happy treatment. 
If people would trust with confidence in the cost of the transport, these attempts would certainly succeed better, and the universal 
sympathy for private plantations would be in consequence aroused and increased. 
Mr. Van Gorkom says, in reference to the Calisaya Dr. Scheffer has confirmed my supposition that the seeds ripened in 
Java of the plants raised by Junghuhn (5000 plants) are not Calisaya; indeed, this sort of Cinchona appears, like the Pa.lmdiana, 
to be a sort hitherto unknown. It is not described by Weddell. Miquel is closely examining it. These trees grow splendidly, 
and contain the double quantity of alkaloids (0-7 = 13 per cent.) compared with the Pahudiana. Would the trade purchase well 
such a bark ? Should this question be answered in the affirmative, I could easily bring 10,000 pounds into the market, for I have 
caused the plantations of this sort in the year 1864 to be lightened, and have constantly kept the eye upon them, so that the 
beautiful high and strong trees should remain. The greater part of these are eight years old, and hundreds of these are to be 
found which could give three to five pounds of bark, whilst I will take as a mean produce only two pounds.”
