REPORT OF THE CULTIVATION OF CINCHON2E AT DARJEELING 
DURING THE MONTH OF OCTOBER, 1865. 
From T. AndersonEsq., M.D., Superintendent, Botanical Gardens, and in charge of 
Cinchona cultivation in Bengal, to S. C. Bayley, Esq., Junior Secretary to the Go¬ 
vernment of Bengal, dated the 3rd January, 1866. 
I have the honour to transmit herewith the Report of the Cinchona cultivation at 
Darjeeling for the month of October, 1865. 
Report for the Month of October. 
I am glad to be able to report the continued success of the cultivation. The number 
of cuttings made during the month was 9615, making a total number of plants and 
cuttings in all stages of growth 108,962. The alterations in the mode of growing the 
plants from which cuttings are obtained has been completed for all the species. The 
full number of stock plants for cutting (10,000) has been attained in the case of 
C. succirubra and C. officinalis, but some months must elapse before the number of 
stock plants of C. micrantha is completed. 
As I possess only 142 plants and cuttings of C. Calisaya, this valuable species must 
be cultivated under the shelter of glass for some years longer. During the month 
14,500 well-rooted plants of C. succirubra were planted in open-air beds, from which 
they will be transferred in April next to the open ground. 
2. The first public sale of Cinchonas took place on the 2nd October. Three purchasers 
attended, who among them bought the 1000 plants offered for sale at the upset price of 
four annas each: only C. officinalis was sold. 
3. The temperature of the past month has been considerably lower than that of Sep¬ 
tember, the greatest difference being in the mean minimum temperature from the clear 
cloudless nights favouring radiation. 
4. The rainfall has also greatly diminished, only one and a half inches of rain were 
recorded during the month, making a total fall of 153-08 inches from the 1st January. 
The mean maximum temperature at the fourth plantation was 80 06. The mean mini¬ 
mum 59*19, and the mean temperature of the month 69-62. 
5. At the fifth and lowest plantation, nine observations of the minimum thermometer 
give a minimum temperature of 61-3. 
6. This decrease in the temperature, accompanied by dryness of the atmosphere, has 
affected the growth of the plants. The period of rest is rapidly approaching when the 
plants will remain almost dormant.
