To the Editor of the "Gardener's Chronicle."

I am very glad that my letter and your remarks on the improvement

of cotton in India have attracted the attention of so able a

correspondent as G. F. R. (Dr. Royle), who appears to be

conversant with a good deal of what has been attempted there. No

doubt there are, as he states, great diversities of soil and

climate in so extensive a country as India; and if so, although

there may be some which are not adapted to the growth of either

the _Gossypium Barbadense_ or the _Gossypium Peruvianum_, there

must be both soil and climate suited to them in various localities

in that country.

My chief reason for suspecting that the injury arises from the new

kinds hybridizing with the indigenous cotton, is, that very good

cotton has been grown from both varieties in the first generation,

but when the seed from this first crop is sown again, the quality

always deteriorates (at least all the gentlemen say so with whom I

have conversed on this subject). I have a sample of Indian-grown

cotton of excellent quality from Pernambuco seed, worth twice as

much as the best Surat cotton I ever saw; but I cannot learn that

anything deserving the name of aught but a sample was ever

obtained. We hear of no increase in the quantity of this improved

variety; it does not--like cotton in the United States--go on from

ten bags to ten thousand, in eight or ten years; on the contrary,

so far as I can learn, it dwindles away to nothing. The Tinnivelly

cotton brought forward as an example by your correspondent is no

exception to this--it is no more like Bourbon cotton, than Bowed

cotton is like Sea Island--at least none that I ever saw. Bourbon

is a long, silky-stapled cotton, whilst Tinnivelly has the

shortness and inequality of fibre common to most of the cotton of

India. It is generally much cleaner than the cotton grown on the

western side of India, but this arises from the greater care in

picking it.

An intelligent friend of mine, now in India, says that the pod of

cotton is overhung by a brown leaf (bractea?), and if the cotton

is gathered early in the morning, whilst the dew is on the plant,

this leaf is tough and does not break, and the cotton is gathered

clean; but if it is picked after the dew has evaporated, this leaf

is brittle, and gets mixed with the cotton in the picking. But he

says that no persuasion can induce the ryots to keep that which is

picked in the morning from that which is gathered in the heat of

the day. He also suggests that the cotton should be irrigated

during its growth, and alleges as a motive for doing this, that in

Egypt and Peru no good cotton can be grown without resorting to

it. But the cases are not exactly parallel, inasmuch as no rain

falls in either of these countries, whilst rain is most abundant

in India, eighty or ninety inches of rain sometimes falling at

Bombay in three months during the monsoon.

Another intelligent gentleman with whom I have conversed on this

subject since my former letter was written, and who has resided at

Bombay many years, where he has paid much attention to this

subject, tells me that the gentleman entrusted by the East India

Company with the management of one of the experimental cotton

estates, assures him he has grown excellent Orleans cotton, and

that the ryots were so satisfied with its superiority over the

indigenous kind that 1,200 begahs (say 300 acres) were planted

with it. But this was two years ago, and as the disturbances took

place in this very neighbourhood, he fears these plantations have

perished, as he heard no more of the matter, and had omitted to

inquire of the gentleman entrusted with the management.

I reserved this until I saw the second letter from your

correspondent G. F. R., which I have now read, as well as an

article on the same subject in the "Manchester Guardian," in which

it is stated that 20,000 acres are now under cultivation, planted

with this improved cotton. I fear this is too good news to be

true. My informant is a gentleman who was in correspondence with

Mr. Mercer, the superintendent of these cotton estates, or some of

them, and I have again questioned him. He says that the crop which

would be gathered in March last, would amount to what I have

stated (1,200 begahs), according to Mr. Mercer's letter to him,

but he says it is now twelve months since he heard from Mr.

Mercer, as he left Bombay for England shortly after. His fear was

that none of this cotton would be gathered, as the disturbances

which took place in Central India, and which required so long a

time to quell them, were in this very district. If your

correspondent G. F. R. has got samples of this improved cotton, of

the second or third generation, he would confer a great obligation

upon me by sending me a small sample of it by post. But this is

wandering from what I intended to say, which was most heartily to

thank your correspondent for his second communication, which goes

far to prove the truth of what I had previously supposed, that the

cotton of India is capable of great improvement by being

judiciously crossed with suitable foreign varieties. Your

correspondent thinks if the old varieties deteriorate the new when

growing in proximity to each other, the new ought, for the same

reason, to improve the old; and no doubt they will, but to a much

smaller extent. It is said that a man leaping up into the air

attracts the earth (proportionately) as much as the earth attracts

him, and it may be so with the old and new cotton. What I mean to

say is, that although some of the old sort of cotton might be

hybridized by the new, the improved variety would be in so small a

quantity that a thousand to one the cultivator would never observe

it; and such is the aversion or indifference to anything new among

the natives of India, that if an improved plant were observed, it

is again a thousand to one he would take no pains to preserve it;

and if he did, it is again perhaps a thousand to one that it would

be entirely spoilt in the next generation by being planted among

the indigenous sorts.

I trust your correspondent will continue to favour us with his

communications whenever he has any fresh information on the

subject, which, the more it is considered the more important it

seems to be.
