Chapter 10

In continuing my attempts to grow wheat on the same land year after year, I observed that the crop of 1845 was very seriously injured by the deficient drainage--the old drains having been destroyed by the subsoil plough. It was therefore necessary to replace them; they were accordingly put in four feet deep. This took up so much time, that the season for sowing wheat had gone by, and the ground was cropped with potatoes, which were dug up in September, and the wheat might have been got in early in October; but seeing in your paper that sowing too early was not advisable, and also being carried away by the arguments of the thin-seeders, I deferred sowing until the middle of November, and also put in little seed, and the weather proving very unfavourable when the wheat was coming up, there was not half plant enough in the spring, and I hesitated whether to plough up the ground or to drill in barley. I determined to do the latter. It was put in on the 18th April, and wheat and barley grew up together, and when cut and threshed, it yielded 48 bushels to the acre.

ON THE GRAVELLING OF CLAY SOILS.

There is an old story of a man, who, having a very stony field, determined to experiment on the value of these stones in the growth of his crops.

With this view he divided his field into three equal parts. From No. 1 he gathered all the stones, which he spread upon No. 3, leaving No. 2 in its original condition. He then sowed barley over the whole field, and carefully noted the results. The story ends by saying that No. 1 bore a miserably poor crop, No. 2 a tolerable one, and No. 3 a splendid one.

I quote this story as a text on which I wish to speak as to the advantage of gravelling heavy clay soils. Some weeks since I spent a few days at the village of Milnthorpe, in Westmoreland, and during one day with Mr. Hutton, the celebrated bone-setter, I remarked that the land was very stony, being covered with stones (not pebbles) having very much the appearance of road metal. He replied, that these stones were essential to the fertility of the soil, and said that some years before there was a great demand for such material in the neighbourhood of Preston, and the high prices stimulated the farmers to gather these stones from their land, and send them to Preston; but the consequences were so injurious to the growth of their crops, that they were compelled--at least those who had the means of doing so--to lead stones again upon their land before their crops would grow again with the vigour which they had before the stones were abstracted. This brought to mind what had occurred in my own farm practice. A church was built in the neighbourhood, and the stones for it were hewn on the corner of a field which was afterwards sown with wheat, and I remarked that the straw was much brighter, the ripening was forwarded ten days, and the sample was much better where the stones had been hewn than elsewhere in the field. (The stones of which the church was built were of ordinary sandstone, probably millstone grit.)

Borrowing from this hint, I had the field covered with about 400 cartloads of alluvial gravel (from the bed of the river) to the acre, and the land was then ploughed two furrows deep, one plough following the other. Previous to this gravelling, the land was a stiff, obdurate clay nearly to the surface. The subsequent effect was the doubling, or more probably trebling the value of the land, which has now become a nice friable soil.

I was much amused with the criticisms of some of the neighbouring farmers (men of the old school), one of whom remarked that he had seen land tilled (manured) in various ways before my time, but until now he had never seen a field tilled with cobble-stones. I said, "What is your objection to it, John?" "Why, ye see, it makes th' land so poor." I replied, "Making anything or anybody poor, means robbing them of something. If you had twenty shillings in your pocket, and I filled it up with these cobble-stones, how much poorer would you be? Of what have I robbed this field by putting gravel into it?" "Why, of nothing; but it looks so queer." I said, "John, did you never hear of a man gathering the stones off his field, and then having to lead them back again?" "Yes, I have; but then they were _natural_ to the soil." I said, "What does manuring land mean, but putting something into it of which it is deficient? You don't till a muck-midden. If in stony land stones are essential for the vigorous growth of the crop, is it not exceedingly probable that they will be still more beneficial on stiff land which has no stones in it?"

This is a doctrine I tried many years since to inculcate upon our friend Mechi, and some of his land (I speak of its condition twenty years since) needed such a gravelling as much as any land I ever saw. Whether he adopted my suggestion, or his land remains in the same condition now as then, I don't know; but if it does, I would just suggest to him and to all landed proprietors who own stiff clay lands, if they are near to gravel-pits, to try a small portion by gravelling it freely, and let us hear the results.

COTTON.

_June 1st_, 1842.

J. KINDERMANN, ESQ.

I have for some time intended to call your attention to the importance of attempting to grow fine cotton in Peru, but my inability to do justice to the subject, both from my being practically unacquainted with any mode of growing cotton and my general want of information, has hitherto prevented me; but as I made you a promise to that effect yesterday, I have endeavoured to put a few suggestions on paper, and hope that if they be carefully acted upon, some benefit may be derived from the experiments.

We have been (as you are aware) consumers of Peruvian cotton to some extent for the last six or eight months, and from the observations I have made on it during that time, I have no hesitation in saying that it possesses many excellences: it is long enough (almost too long), very sound in staple, and where well managed of a very good colour. Its defects are coarseness and harshness of staple, and if these could be removed I don't see what is to prevent its rivalling the Egyptian and Sea Islands cotton, any considerable approximation to which would very materially enhance its value, seeing that the highest quotation for Sea Island, was last week 30d. per lb. (2s. 6d.), whilst the highest for Peruvian was no more than 6 1/2 d.

With the view of improving the quality of the cotton in Peru, I would strongly recommend you to send seeds of various kinds, packed in air-tight boxes, particularly Sea Island and Egyptian, which some of the cotton-brokers would easily procure from the spinners using these descriptions, and, judging from what I hear of the climate of both countries, I should think the Egyptian would go to a very similar atmosphere and mode of cultivation to that of the country where it had been raised, which would probably render it more easy to acclimatize, and, of course, make it more likely to succeed than a sort of cotton which had been grown under dissimilar circumstances of soil, climate, and mode of cultivation.

These seeds when sown, ought (with the exceptions hereafter to be mentioned) to be planted at such a distance from all other cottons as to render it very unlikely for the wind or insects to carry the pollen from the flowers of one kind to those of another; for without this precaution, such is the tendency in many genera of plants to hybridize (and I believe, from what I have heard, there is this tendency in the different varieties of cotton) or cross- breed with each other, that, however good the quality in the first instance, they would all revert to the old variety in a year or two in consequence of the great preponderance of that variety over any newly-introduced ones. So much are the growers of turnip-seed for sale in England aware of the importance of attending to this, that the greatest precautions are taken to remove all _cruciform plants_ from the vicinity of the field whilst their turnips are in flower, as there is such a tendency in them all to hybridize that the quality of the seed is often injured by the wild mustard (_Sinapis arvensis_) springing up in the same or the adjoining fields; whilst, on the other hand, by carefully selecting the best bulbs for seed, and by judiciously crossing one variety with another, new sorts are obtained, combining the excellences of both. This leads me to observe, that probably seed of foreign varieties of cotton may not thrive well in the first instance, and I would therefore strongly recommend the gentlemen who may make the experiment carefully to select seed from the plants on their estates which they see are growing the best and finest cotton, and sow them in contact with a few seeds of each of the sorts you may send out, carefully removing them in every instance as far as may be practicable from the vicinity of all other cotton; and then again sowing the seeds which are obtained from the plants thus raised in contiguity to each other, and carefully examining the cotton grown upon each of them, it is more than probable they will find that _some_ of the plants will be varieties partaking of the character of both the parent kinds, and by selecting the best of these and sowing them only (still apart from all other cotton), there is little doubt that much benefit will be derived by the persevering and skilful cultivator.

I have heard it stated that the origin of Sea Island cotton is to be traced to something of this kind. An observing and experimental planter, by carefully examining his cotton, and by sowing his seed only from those plants that produced the finest and longest staple, at last arrived at the excellent quality which is now known by that name.

Look, again, at what has been done in Egypt by the introduction of better varieties of cotton. There these improved varieties have by no means had a fair chance of showing what they are capable of becoming, inasmuch as the wretched cultivator has not the slightest inducement to improve their quality--he gets no more per pound for the finest and cleanest cotton than he does for the coarsest and dirtiest, and therefore it is not very likely to improve under his care. But with all this neglect and want of management, we can see by what it is, what it would most probably become in the hands of an enterprising and intelligent man who knew that every improvement he made in its quality would be to his own advantage. Assuming that your Peruvian friends could so far improve the quality of their cotton as to double its value in this market (and I don't think myself too sanguine in expecting more than this), with very little extra labour nearly all the additional price would be profit.

But supposing even that cross-breeding, or hybridizing, as the horticulturists call it, does not frequently occur naturally in cotton, it is well known that it is very easy to effect it artificially by prematurely unfolding the petals and with fine scissors cutting away all the stamens before impregnation takes place. This requires to be carefully done, so as not to injure the petals, and they will then close again of themselves, and when they expand naturally, then impregnate the stigma of the flower with the pollen of the kind you want to cross with. We owe many of our finest varieties of fruits to this practice. The late Mr. Payne Knight was very successful in raising new varieties of many sorts of fruit in this way, and it appears to me from the experiments I have made that the more frequently this cross- breeding takes place, the more easy (within certain limits) is it to extend it until cultivation has so completely changed the character of the plant that it bears very little resemblance to its original stock. There is nothing growing wild like our cabbages, turnips, and cauliflowers; nor even like our carrots, celery, and asparagus. Where are the originals of our wheat, barley, rye, beans, and peas? Many of these appear to be so completely transformed by cultivation that we don't know where to look for the parent stocks from which they originated. But I am forgetting cotton altogether, yet beg to refer to the preceding paragraph to show how much is owing to careful cultivation, and trust that it may not be without its use if my letter induces your friends to make the experiments here suggested, even though their first attempts are unsuccessful.

This letter was translated into Spanish and circulated in Peru, but with what success I do not know. It was also published in the "Gardener's Chronicle," and led to a reply from Dr. Royle, which occasioned the following letter.

* * * * *

_August 14th_, 1845.

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.

PAPERS ON NATURAL HISTORY.

WRENS' NESTS.

THE Editor of Loudon's "Magazine of Natural History," and one of his contributors, Mr. Jennings, were of opinion that the common Wren never lined its nest with feathers. The following contribution was sent to the "Magazine of Natural History" in consequence of this, and led to some discussion afterwards:--

_April 17th_, 1829.

Mr. Jennings and yourself, in opposition to Montagu, are of opinion that the Wren never lines its nest with feathers; like the knights of the gold-and-silver shield, both sides are right. It is true, many Wrens' nests may be found in which there are no feathers; but did you ever find either eggs or young ones in them?

As far as my observations go, the nest in which the Wren lays its eggs is profusely lined with feathers; but during the period of incubation, the male--apparently from a desire to be doing something--constructs several nests in the vicinity of the first, none of which are lined; and whilst the first nest is so artfully concealed as to be found with difficulty, the last is very often seen. The Wren does not appear to be very careful in the selection of a site for these cock-nests, as they are called in Yorkshire by the schoolboys. I have frequently seen them in the twigs of a thick thorn hedge, under banks, in haystacks, in ivy bushes, in old stumps, in the loopholes of buildings, and in one instance in an old bonnet, which was placed among some peas to frighten away the blackcaps.

_August 15th_, 1831.

TO PROFESSOR RENNIE.

In your edition of Montagu's "Ornithological Dictionary," just published, you say--speaking of the Wren--"An anonymous correspondent of Loudon's 'Magazine of Natural History,' &c. &c.;" and you remark, "There can be no doubt of these supposed 'cock- nests' being nothing more than unfinished structures of paired birds; otherwise, the story would require the support of very strong evidence to render it credible."

As I am the anonymous correspondent alluded to, I forward you a few observations of facts tending, as I think, to confirm my view of the question.

In the first place, these nests are far too abundant for the birds, which are not plentiful--at least, in this neighbourhood. Again, it is at least five to one that any Wren's nest which is found during the summer without a lining of hair or feathers is ever completed, or has any eggs in it. This I have verified in a hundred instances, when, having found Wrens' nests, I have visited them again at intervals, for the purpose of ascertaining whether my opinion of cock-nests was correct.

Farther, in a small wood adjoining my garden, where I was certain there was only one pair of Wrens, I found at least half-a-dozen nests, not one of which was either lined with feathers or ever had eggs in it; although I discovered they were not all deserted, as I found an old bird roosting in one of them. I was induced to be more particular in my remarks in consequence of my seeing Mr. Jennings's remarks in the "Magazine of Natural History;" and I searched, as I supposed, every bank, bush, and stump in the wood two or three times before I could find the breeding-nest, which I at last discovered in the twigs of a willow on the bank of the river, in the centre of a bunch of tangled grass, cotton waste, and straws which had been left there by the floods, and which the bird had apparently excavated and in it formed its nest, which was profusely lined with rooks' feathers.

The fear of being thought tedious prevents my giving other facts which tend, as I think, to prove the correctness of my opinion; however, I will just add that all the persons with whom I have conversed who take an interest in such pursuits, agree with me in opinion in this matter.

The nest I have just spoken of was also a strong proof that Wrens, although they may not always adapt their materials to the locality they have chosen for a nest, frequently do so; and if this is not with the intention of concealing it, but merely because the materials are at hand, it serves the purpose of concealment also, and very effectually. The one I am speaking of was so exactly like the other lumps of rubbish which had been left by the floods in the same bush, that I did not discover that it was a Wren's nest until I had pulled it out of the twigs; and if a Wren builds its nest in a haystack--which it frequently does--the front of the nest is almost invariably composed of the hay from the stack, which prevents its being seen much more effectually than if the moss of which the body of the nest is composed were visible on the outside.
