young plants. I should be disposed: to’ recommend: that the experi- — 
“ment should be pushed om steadily and regularly, and that. 150 acres — 
should be added annually to the plantations, for a period of nine orten | 
years at least. Should the lopping and pruning produce the quantity | 
of bark anticipated by Mr. M‘Ivor, the return will be sufficient to | 
repay the capital expended in about ten years, inclusive of inter- | 
est. "The cost to the Government would be at the utmost, supposing : 
here to be no return in the interval, about £100 per acre, and the — 
return even at present prices would be at least £16,000 per aere. | 
“The number of trees which an acre will cover is about 650, and it | 
is calculated that each tree will produce after ten years’ growth, 5 3 
bs. weight of bark annually; the yield per acre will thus be 8250 | 
bs., and for 160 acres 480,000 lbs., or upwards of 200 tons, at six- | 
pence per pound, which I believe to be a low price. This will give | 
£12,060 per annum as the return upon the 160 acres, the annual ex- i 
pense of management being £1320.” 1 
On October 22nd, the Madras Government iecordod the following 7

“The Government resolve to bring the papers relating to the ex- 4 
periments now being made upon the Neilgherries in the cultivation of | 
the different species of Chinchona, to the notice of the Secretary of : 
State. The Dodabetta plantation extended at present over 60 acres, | 
of which 15 have been already occupied, while the remaining 45-are | 
in various stages of preparation, and will be planted before the end of 
the current year: The Neddiwuttum site comprises 150 acres, of | 
which 21 have been planted, and the remainder more or less pre- 4 
pared. The actual plantation will be extended from 21 to 100 aeres | 
in the course of the present calendar year. The rapid propagation of , 
the plants has enabled us to offer a considerable number for sale early 4 
“next year, at the moderate price of 4 annas or sixpence each." - a
