The average of all these experiments being 56 per cent. only. The result of M. Avequin, on Louisiana cane, was 50 per cent. Mr.

Thompson, of Jamaica, states 50 per cent. as the average throughout the island of Martinique. Dr. Evans ventures 47 per cent. as the lowest, and 61 per cent. as the highest in the West Indies. A mill in Madeira gave 47.5 and 70.2 of juice--the larger yield being obtained by bracing the horizontal rollers more than usually tight, and introducing only a few canes at a time, the motive power being cattle.

The three roller mill has the disadvantage of re-absorbing a part of the cane juice in the spongy mega.s.s, (or trash as it is termed in the West Indies), and a loss of power.

Those with five rollers have been used in Cuba, Bourbon and the Mauritius, which gave 70 per cent., but a great increase of motive power is necessary. Four roller mills, two below and two above, requiring little more motive power than three rollers, have given 70 to 75 per cent of juice.

Some years since, the East India Company inst.i.tuted inquiries relative to the cultivation of the sugar cane in Hindostan, and the information obtained was published in a large folio volume. The Reports furnished by their officers, from almost every district, concur in stating that there were three kinds cultivated:--1. The purple. 2. The white. 3. A variety of the white, requiring a large supply of water. The epitome of the Reports affords this information:--

1. The purple colored cane yields a sweeter, richer juice, than the yellow or light colored, but in less quant.i.ty, and is harder to press.

Grows on dry lands. Scarce any other sort in Beerbhoom, much in Radnagore, some about Santipore, mixed with light colored cane. Grows also near Calcutta; in some fields separate, in others mixed with pooree or light colored cane. When eaten raw, is more dry and pithy in the mouth, but esteemed better sugar than the pooree, and appears to be the superior sort of cane. Persons who have been West Indian planters do not know it as a West Indian cane.

2. The light colored cane, yellow, inclining to white; deeper yellow when ripe, and on rich ground, it is the same sort as that which grows in the West India Islands; softer, more juicy than the Cadjoolee, but juice less rich, and produces sugar less strong; requires seven maunds of pooree juice to make as much goor or insp.i.s.sated juice as is produced from six of the Cadjoolee. Much of this kind is brought to the Calcutta markets, and eaten raw.

3. The white variety, which grows in swampy, lands, is light colored, and grows to a great height. Its juice is more watery, and yields a weaker sugar than the Cadjoolee. However, as much of Bengal consists of low grounds, and as the upland canes are liable to suffer from drought, it may be advisable to encourage the cultivation of it, should the sugar it produces be approved, though in a less degree than other sugars, in order to guard against the effects of dry seasons.

Experience alone can determine how far the idea of encouraging this sort may answer.

Besides the foregoing, several kinds are now known to the Indian planter. One of them, the China sugar cane, was considered by Dr.

Roxburgh to be a distinct species, and distinguished by him as _Saccharum sinensis_. It was introduced into India in 1796, by Earl Cornwallis, as being superior to the native kinds. It is characterised by a hardness which effectually resists most of the country rude mills; but this hardness is importantly beneficial, inasmuch as that it withstands the attack of the white ants, hogs, and jackals, which destroy annually a large portion of the common cane.[18] Dr. Buchanan found that four kinds are known in Mysore. Two of these are evidently the purple and white generally known; but as this is not distinctly stated, I have retained the form in which he notices them. _Restali_, the native sugar of the Mysore, can only be planted in the last two weeks of March and two first of April. It completes its growth in twelve months, and does not survive for a second crop. Its cultivation has been superseded by the other.

_Putta-putti_.--This was introduced from Arcot, during the reign of Hyder Ali. It is the only one from which the natives can extract sugar; it also produces the best _Bella_ or _Jaggery_. It can be planted at the same season as the other, as well as at the end of July and beginning of August. It is fourteen months in completing its growth; but the stools produce a second crop, like the ratoons of the West Indies, which ripen in twelve months.

_Maracabo_, _Cuttaycabo_.--These two are very small, seldom exceeding half an inch in diameter; yet in some districts of Mysore, as about Colar, the last-named is the variety usually cultivated; but this arises from its requiring less water than the larger varieties.

The best varieties are those introduced from the Islands of Otaheite and Bourbon. Hindostan is indebted for their introduction to Captain Sleeman, who brought them hither from the Mauritius in 1827. He committed them to Dr. Wallich, under whose care, at the Botanic Garden, they have flourished, and been the source from whence the benefit has been generally diffused. Their superiority over those which have been usually cultivated by the natives has been completely established. The largest of the Hindostan canes, ripe and trimmed ready for the mill, has never been found to exceed five pounds; but it is not uncommon for an Otaheite cane,[19] under similar circ.u.mstances, to weigh seven pounds. The extra weight arises proportionately from an increased secretion of superior sap. The sugar is more abundant, granulates more readily, and has less sc.u.m. Other superior qualities are, that the canes ripen earlier, and are less injured by the occurrence of protracted dry weather.

Of the history of the sugar cane a popular tradition obtains amongst the natives, that, in very ancient times, a vessel belonging to their country chanced by accident to leave one of her crew, under a desperate fit of sickness, at a desert island, at a considerable distance in the Eastern Seas, and that, returning by the same route, curiosity prompted them to inquire after the fate of their companion, when, to their utter astonishment, the man presented himself to their view, completely recovered from his sickness, and even in a state of more than common health. With anxiety they inquired for the physic he had so successfully applied, and were conducted by him to the sugar cane, on which he acquainted them he had solely subsisted from the time of their departure. Attracted by such powerful recommendation, every care and attention was bestowed, we may suppose, to convey such an invaluable acquisition to their own lands, where the soil and climate have mutually since contributed to its present prosperity.

_Soil_.--The soil best suiting the sugar cane is aluminous rather than the contrary, tenacious without being heavy, readily allowing excessive moisture to drain away, yet not light. One gentleman, Mr.

Ballard, has endeavoured to make this point clear by describing the most favorable soils about Gazepore as "_light clays_," called there _Mootearee_, or _doansa_, according as there is more or less sand in their composition.--_Trans. Agri-Hort. Soc._ i. 121.

Mr. Peddington seems to think that calcareous matter, and iron in the state of _peroxide_, are essential to be present in a soil for the production of the superior sugar cane. There can be no doubt that the calcareous matter is necessary, but experience is opposed to his opinion relative to the peroxide.

The soil preferred at Radnagore is there distinguished as the soil of "two qualities," being a mixture of rich clay and sand, and which Mr.

Touchet believed to be known in England as a light brick mould.

About Rungpore, Dinajpoor, and other places where the ground is low, they raise the beds where the cane is to be planted four or five feet above the level of the land adjacent.

The experience of Dr. Roxburgh agrees with the preceding statements.

He says, "The soil that suits the cane best in this climate is, a rich vegetable earth, which on exposure to the air readily crumbles down into very fine mould. It is also necessary for it to be of such a level as allows of its being watered from the river by simply damming it up (which almost the whole of the land adjoining to this river, the G.o.davery, admits of), and yet so high as to be easily drained during heavy rains. Such a soil, and in such a situation, having been well meliorated by various crops of leguminous plants, or fallowing, for two or three years, is slightly manured, or has had for some time cattle pent upon it. A favourite manure for the cane with the Hindoo farmer is the rotten straw of green and black pessaloo (_Phaseolus Mungo max_)."[20] Many accordant opinions might be added to the preceding, but it seems only necessary to observe further, that "the sugar cane requires a soil sufficiently elevated to be entirely free from inundation, but not so high as to be deprived of moisture, or as to encourage the production of white ants (_termes_)."

The sugar cane is an exhausting crop, and it is seldom cultivated by the ryot more frequently than once in three or four years on the same land. During the intermediate period, such plants are grown as are found to improve the soil, of which, says Dr. Tennant, the Indian farmer is a perfect judge. They find the leguminous tribe the best for the purpose. Such long intervals of repose from the cane would not be requisite if a better system of manuring were adopted.

Mr. J. Prinsep has recorded the following a.n.a.lysis of three soils distinguished for producing sugar. They were all a soft, fine-grained alluvium, without pebbles. No. 1 was from a village called Mothe, on the Sarjee, about ten miles north of the Ganges, at Buxar, and the others from the south bank of the Ganges, near the same place. There is a substratum of _kunkar_ throughout the whole of that part of the country, and to some mixture of this earth with the surface soil the fertility of the latter is ascribed:--

1 2 3 Hygrometric moisture, on drying at 212 deg. 2.5 2.1 3.6 Carbonaceous and vegetable matter, on calcination 1.8 2.1 4.0 Carbonate of lime (No. 3 effervesced) 1.6 0.6 3.9 Alkaline salt, soluble 1.0 1.1 0.3 Silex and alumina 94.1 94.1 88.2 ----- ----- ----- 100.0 100.0 100.0

The earths unfortunately were not separated. Mr. Prinsep says the two first were chiefly of sand, and the third somewhat argillaceous. The former required irrigation, but the other was sufficiently retentive of moisture to render it unnecessary.--(Journ. Asiatic Soc., ii. 435.)

_Manures_.--The sugar cane being one of the most valued crops of the ryot, he always devotes to it a portion of the fertilising matters he has at command, though in every instance this is too small.

In the Rajahmundry district, previously to planting, the soil is slightly manured, either by having cattle folded upon it, or by a light covering of the rotten straw of the green and black pessalloo, which is here a favourite fertiliser. In some parts of Mysore the mud from the bottom of tanks is employed, and this practice is more generally adopted in other places. Thus the fields being divided by deep ditches in Dinajpoor, the mud from which is enriched by the remains of decayed aquatic plants and animals, forms an excellent manure for the sugar cane, and of this the ryots make use, spreading it over the surface before the ploughing is commenced; and when that operation is completed, the soil is further fertilised by a dressing of oil-cake and ashes.

Crushed bones would unquestionably be of the greatest benefit if applied to the sugar cane crop. Not only would their animal matter serve as food for the plants, but the phosphate of lime of the bones is one of the chief saline const.i.tuents of the sugar cane.

Salt is another valuable manure for this crop. Dr. Nugent, in a Report made to the Agricultural Society of Antigua, observes that salt has been found a valuable auxiliary in cultivating the sugar cane. Many trials of it, he says, have been made during successive seasons, applied generally to the extent of about nine or ten bushels per acre.

It destroys grubs and other insects, and gives the canes an increased vigor and ability to resist drought. It is a singular remark of the intelligent traveller, M. de Humboldt, while speaking of the practice adopted in the Missions of the Orinoco, when a coco-nut plantation is made, of throwing a certain quant.i.ty of salt into the hole which receives the nut; that of all the plants cultivated by man there are only the sugar cane, the plantain, the mammee, and the Avocado pear, which endure equally irrigation with fresh and salt water.

In the West Indies, when the cane is affected by what is called there the _blast_, which is a withering or drying up of the plants, an unfailing remedy is found to be watering them with an infusion of dung in salt water.[21] _Preparation of soil_.--In the Rajahmundry district, during the months of April and May, the ground is frequently ploughed, until brought into a very fine tilth. About the end of May, or beginning of June, the rains usually commence, and the canes are then to be planted. If the rains do not set in so early, the land is flooded artificially, and when converted into a soft mud, whether by the rain or by flooding, the canes are planted.

In Mysore the ground is watered for three days, and then, after drying for the same period, ploughing commences, this operation being repeated five times during the following eight days. The clods during this time are broken small by an instrument called _colkudali_. The field is then manured and ploughed a sixth time. After fifteen days it is ploughed again, twice in the course of one or two days. After a lapse of eight days it is ploughed a ninth time. Altogether these operations occupy about forty-four days.

For planting, which is done six days, an implement called _yella kudali_ is employed.

In Dinajpoor, "the field, from about the middle of October until about the 10th of January, receives ten or twelve double ploughings, and after each is smoothed with the _moyi_. During the last three months of this time it is manured with cow-dung and mud from ponds and ditches. On this account, the land fit for sugar cane is generally divided into fields by wide ditches, into which much mud is washed by the rain, and is again thrown on the fields when the country dries, and leaves it enriched by innumerable aquatic vegetables and animals that have died as the water left them. When the ploughing has been completed, the field is manured with ashes and oil-cake."

About Malda, "the land is first ploughed in the month of Cartick, length and breadth ways, and harrowed in like manner; four or five days after it is again ploughed and harrowed, as before, twice. In the month of Aghun, the whole land is covered with fresh earth, again twice ploughed, and harrowed in different directions, and then manured with dung. Fifteen or twenty days afterwards it is to be twice ploughed, as before; eight or ten days after which, it is to be slightly manured with dung, and the refuse of oil, mixed together; then twice ploughed and harrowed in different directions, so that the clods of earth brought be well mixed together with the land. This preparation continues until the 20th or 25th of the month Pows."

In the vicinity of Dacca, during "Cautic or Augun (October, November) the Ryots begin to prepare their ground. They first dig a trench round their fields, and raise a mound of about three feet in height. If the ground to be cultivated is waste, about nine inches of the surface are taken off, and thrown without the enclosure. The ground is ploughed to the depth of nine inches more. The clods are broken, and the earth made fine. In Maug or Faugun (January, February) the sugar cane is planted; a month afterwards earth is raised about the plants; after another month this is repeated. The crop is cut in Poous and Maug (December, January). If the ground be not waste, but cultivated, the surface is not taken off. After cutting the crop, it is not usual again to grow sugar cane on the same ground for eighteen months, on account of the indifferent produce afforded by a more early planting.

In the Zillah, North Mooradabad, the land is broken up at the end of June. After the rains have ceased it is manured, and has eight or ten ploughings. This clears it of weeds. In February it is again manured and ploughed four or five times, and just before the sets are planted, some dung, four cart-loads to each cutcha beegah of low land, and five cart-loads to high land, are added. The land is well rolled after the four last ploughings, and again after the cuttings are set.

About Benares and the neighbouring districts, Mr. Haines says, that owing to the hot winds which prevail "from March until the setting in of the annual rains in June or July, the lands remain fallow till that period. In the mean time, those fields that are selected for sugar cane are partially manured by throwing upon them all manner of rubbish they can collect, and by herding their buffaloes and cattle upon them at night, though most of the manure from the latter source is again collected and dried for fuel.

When the annual rains have fairly set in, and the a.s.sarree crops sown (in some instances I have seen an a.s.sarree crop taken from the lands intended for sugar cane), they commence ploughing the cane lands, and continue to do so four or five times monthly (as they consider the greater number of times the fields are turned up at this period of the season, the better the crop of cane will be), till the end of October, continuing to throw on the little manure they can collect.

Towards the end of October, and in November, their ploughs are much engaged in sowing their winter (or rubbee) crops of wheat, barley, grain, &c.; and at this period they make arrangements with the shepherds who have large flocks of sheep, to fold them upon the fields at night, for which they pay so much per beegah in grain.

During the latter part of November, and early in December, the fields are again ploughed well, and all gra.s.s, weeds, &c., removed with the hoe; then the surface of the field is made as smooth as possible by putting the hengah (a piece of wood eight to ten feet in length, and five to six inches in breadth, and three or four inches in thickness, drawn by two pairs of bullocks, and the man standing upon the wood to give it weight), over several times for three or four days in succession. This makes the surface of the field very even and somewhat hard, which prevents the sun and dry west wind from abstracting the moisture, which is of great importance at this period of the season, for, should there be no rain, there would not be sufficient moisture at the time of planting the cane to cause vegetation.

In this state the land remains till the time of planting the cane cuttings, which is generally the 1st to the 15th of February; but should there have been a fall of rain in the mean time, or excess of moisture appear, the field is again ploughed, and the hengah put over as before.

A day or two previous to planting the cane, the field is ploughed and the hengah lightly put over."--(Trans. Agri-Hort. Soc. vi. 4, 5.)

_Sets_.--When the canes are cut at harvest time, twelve or eighteen inches of their tops are usually taken off, and stored, to be employed for sets. Each top has several joints, from each of which a shoot rises, but seldom more than one or two arrive at a proper growth.

When first cut from the stem, the tops intended for plants are tied in bundles of forty or fifty each, and are carefully kept moist. In a few days they put forth new leaves: they are then cleared of the old leaves, and separately dipped into a mixture of cow-dung, pressed mustard seed, and water. A dry spot is prepared, and rich loose mould and a small quant.i.ty of pressed mustard-seed; the plants are separately placed therein, a small quant.i.ty of earth strewed amongst them, and then covered with leaves and gra.s.s to preserve them from heat. Ten or twelve days afterwards they are planted in the fields.

In Burdwan, the tops, before they are planted, are cut into pieces from four to six inches long, so that there are not more than four knots in each. Two or three of these plant tops are put together in the ground, and a beegah requires from 7,500 to 10,240 plants.

In Rungpore and Dinajpoor, about 9,000 plants are required for a beegah, each being about a foot in length.

In Beerbhoom, 3,000 plants are said to be requisite for a beegah, each cane top being about fifteen inches long.

Near Calcutta, from 3,000 to 8,000 plants are required for a beegah, according to the goodness of the soil, the worst soil needing most plants. In Mysore an acre contains 2,420 stools, and yields about 11,000 ripe canes.
