The next step is the treatment of the juices expressed by the rollers and collected in the troughs that carry it onward. The operations are highly technical, and different methods are employed in different mills. The first operation is one of purification. The juice, as it comes from the rollers, carries such materials as glucose, salts, organic acids, and other impurities, that must be removed. For this, lime is the principal agent. The details of it all would be as tedious here as they are complicated in the mill. The percentages of the different impurities vary with the variation of the soils in which the cane is grown. The next step, following clarification, is evaporation, the boiling out of a large percentage of the water carried in the juice. For this purpose, a vacuum system is used, making possible a more rapid evaporation with a smaller expenditure of fuel. These two operations, clarification and evaporation by the use of the vacuum, are merely improved methods for doing, on a large scale, what was formerly done by boiling in pans or kettles, on a small scale. That method is still used in many parts of the world, and even in the United States, in a small way. For special reasons, it is still used on some of the Louisiana plantations; it is common in the farm production of sorghum molasses in the South; and in the manufacture of maple sugar in the North. In those places, the juices are boiled in open pans or kettles, the impurities skimmed off as they rise, and the boiling, for evaporation, is continued until a proper consistency is reached, for molasses in the case of sorghum and for crystallization in the case of plantation and maple sugars. There is an old story of an erratic New England trader, in Newburyport, who called himself Lord Timothy Dexter. In one of his shipments to the West Indies, a hundred and fifty years ago, this picturesque individual included a consignment of "warming pans," shallow metal basins with a cover and a long wooden handle, used for warming beds on cold winter nights. The basin was filled with coals from the fireplace, and then moved about between the sheets to take off the chill. He was not a little ridiculed by his acquaintances for sending such merchandise where it could not possibly be needed, but it is said that he made considerable money out of his enterprise. With the covers removed, the long-handled, shallow basins proved admirably adapted for use in skimming the sugar in the boiling-pans. But the old-fashioned method would be impossible today.
The different operations are too complicated and too technical for more than a reference to the purpose of the successive processes. Clarification and evaporation having been completed, the next step is crystallization, also a complicated operation. When this is done, there remains a dark brown mass consisting of sugar crystals and molasses, and the next step is the removal of all except a small percentage of the molasses. This is accomplished by what are called the centrifugals, deep bowls with perforated walls, whirled at two or three thousand revolutions a minute. This expels the greater part of the molasses, and leaves a mass of yellow-brown crystals, the coloring being due to the molasses remaining. This is the raw sugar of commerce. Most of Cuba's raw product is classed as "96 degree centrifugals," that is, the raw sugar, as it comes from the centrifugal machines and is bagged for shipment, is of 96 degrees of sugar purity. This is shipped to market, usually in full cargo lots. There it goes to the refineries, where it is melted, clarified, evaporated, and crystallized. This second clarification removes practically everything except the pure crystallized sugar of the market and the table. It is then an article of daily use in every household, and a subject of everlasting debate in Congress.

VARIOUS PRODUCTS AND INDUSTRIES
The Encyclopædia Britannica states that "although the fact has been controverted, there cannot be a doubt that the knowledge of tobacco and its uses came to the rest of the world from America. As the continent was opened up and explored, it became evident that the consumption of tobacco, especially by smoking, was a universal and immemorial usage, in many cases bound up with the most significant and solemn tribal ceremonials." The name "tobacco" was originally the name of the appliance in which it was smoked and not of the plant itself, just as the term "chowder" comes from the vessel (chaudière) in which the compound was prepared. The tobacco plant was first taken to Europe in 1558, by Francisco Fernandez, a physician who had been sent to Mexico by Philip II to investigate the products of that country. The English, however, appear to have been the first Europeans to adopt the smoking habit, and Sir Walter Raleigh was notable for his indulgence in the weed. He is said to have called for a solacing pipe just before his execution. Very soon after their arrival, in 1607, the Virginia settlers engaged in the cultivation of tobacco, and it soon became the most important commercial product of the colony. Smoking, as practiced in this country, appears to have been largely, and perhaps only, by means of pipes generally similar to those now in use. The contents of ancient Indian mounds, or tumuli, opened in Ohio, Indiana, Illinois, and Iowa, show the use of pipes by the aborigines probably centuries before the discoveries by Columbus. Many were elaborately carved in porphyry or some other hard stone, while others were made of baked clay. Others, many of them also elaborately carved and ornamented, have been found in Mexico. Roman antiquities show many pipes, but they do not show the use of tobacco. It is assumed that they were used for burning incense, or for smoking some aromatic herb or hemp.
The first knowledge of the use of the plant in Cuba was in November, 1492, when Columbus, on landing near Nuevitas, sent his messengers inland to greet the supposed ruler of a supposed great Asiatic empire. Washington Irving thus reports the story as it was told by Navarete, the Spanish historian. Referring to those messengers, he says: "They beheld several of the natives going about with firebrands in their hands, and certain dried herbs which they rolled up in a leaf, and lighting one end, put the other in their mouths, and continued exhaling and puffing out the smoke. A roll of this kind they called a tobacco, a name since transferred to the plant of which the rolls were made. The Spaniards, although prepared to meet with wonders, were struck with astonishment at this singular and apparently nauseous indulgence." A few years later, a different method was reported, by Columbus, as employed in Hispaniola. This consisted of inhaling the fumes of the leaf through a Y-shaped device applied to the nostrils. This operation is said to have produced intoxication and stupefaction, which appears to have been the desired result. The old name still continues in Cuba, and if a smoker wants a cigar, he will get it by calling for a "tobacco." The production of the plant is, next to sugar, Cuba's most important commercial industry. Its early history is only imperfectly known. There was probably very little commercial production during the 16th Century, for the reason that there was then no demand for it. The demand came in the first half of the 17th Century, and by the middle of that period tobacco was known and used in practically all civilized countries. The demand for it spread very rapidly, in spite of papal fulminations and penal enactments. For a time, in Russia, the noses of smokers were cut off. The early part of the 18th Century saw Cuba actively engaged in production and shipment. In 1717, Cuba's tobacco was made a monopoly of the Spanish Government. Under that system, production was regulated and prices were fixed by the agents of the government, in utter disregard of the welfare of the producers. As a result, several serious riots occurred. In 1723, a large number of planters refused to accept the terms offered by the officials, and destroyed the crops of those who did accept, a condition repeated in the State of Kentucky a few years ago, the only difference being that in the Cuban experience the monopolist was the Government, and in Kentucky it was a corporation. A few years later, in 1734, the Cuban monopoly was sold to Don José Tallapiedra who contracted to ship to Spain, annually, three million pounds of tobacco. The contract was afterward given to another, but control was resumed by the Crown, in 1760. Finally, in 1817, cultivation and trade were declared to be free, subject only to taxation.
STREET IN CAMAGUEY
In time, it became known that the choicest tobacco in the market came from the western end of Cuba, from the Province of Pinar del Rio. It was given a distinct name, Vuelta Abajo, a term variously translated but referring to the downward bend of the section of the island in which that grade is produced. Here is grown a tobacco that, thus far, has been impossible of production elsewhere. Many experiments have been tried, in Cuba and in other countries. Soils have been analyzed by chemists; seeds from the Vuelta Abajo have been planted; and localities have been sought where climatic conditions corresponded. No success has been attained. Nor is the crop of that region produced on an extensive scale, that is, the choicer leaf. Not all of the tobacco is of the finest grade, although most of it is of high quality. There are what may be called "patches" of ground, known to the experts, on which the best is produced, for reasons not yet clearly determined. The fact is well known, but the causes are somewhat mysterious. Nor does the plant of this region appear to be susceptible of improvement through any modern, scientific systems of cultivation. The quality deteriorates rather than improves as a result of artificial fertilizers. The people of the region, cultivating this special product through generation after generation, seem to have developed a peculiar instinct for its treatment. It is not impossible that a time may come when scientific soil selection, seed selection, special cultivation, irrigation, and other systems, singly or in combination, will make possible the production of a standardized high-grade leaf in much greater quantity than heretofore, but it seems little probable that anything so produced will excel or even equal the best produced by these expert vegueros by their indefinable but thorough knowledge of the minutest peculiarities of this peculiar plant. Thus far, it has not even been possible to produce it elsewhere in the island. It has been tried outside of the fairly defined area of its production, tried by men who knew it thoroughly within that area, tried from the same seed, from soils that seem quite the same. But all failed. Science may some day definitely locate the reasons, just as it may find the reason for deterioration in the quality of Cuban tobacco eastward from that area. The tobacco of Havana Province is excellent, but inferior to that of Pinar del Rio. The growth of Santa Clara Province is of good quality, but inferior to that of Havana Province, while the tobacco of eastern Cuba is little short of an offence to a discriminating taste.
Tobacco is grown from seeds, planted in specially prepared seed beds. Seeding is begun in the early autumn. When the young plant has attained a proper height, about eight or ten inches, it is removed to, and planted in, the field of its final growth. This preliminary process demands skill, knowledge, and careful attention equal, perhaps, to the requirements of the later stages. Experiments have been made with mechanical appliances, but most of the work is still done by hand, particularly in the area producing the better qualities of leaf. From the time of transplanting, it is watched with the greatest care. A constant battle is waged with weeds and insect life, and water must be brought if the season is too dry. If rains are excessive, as they sometimes are, the crop may be partly or wholly destroyed, as it was in the autumn of 1914. The plant matures in January, after four months of constant watchfulness and labor, in cultivation, pruning, and protection from worms and insects. When the leaves are properly ripened, the stalks are cut in sections, two leaves to a section. These are hung on poles and taken to the drying sheds where they are suspended for three or more weeks. The time of this process, and its results, depend upon moisture, temperature, and treatment. All this is again an operation demanding expert knowledge and constant care. When properly cured, the leaves are packed in bales of about 110 pounds each, and are then ready for the market. Because of the varying conditions under which the leaf is produced, from year to year, it is somewhat difficult to determine with any accuracy the increase in the industry. Broadly, the output appears to have been practically doubled in the last twenty years, a growth attributed to the new economic conditions, to the extension of transportation facilities that have made possible the opening of new areas to cultivation, and to the investment of capital, largely American capital. The exports show, generally, a material increase in sales of leaf tobacco and some decline in sales of cigars. The principal market for the leaf, for about 85 per cent of it, is in the United States where it is made, with more or less honesty, into "all-Havana" cigars. This country, however, takes only about a third of Cuba's cigar output. The United Kingdom takes about as much of that product as we do, and Germany, in normal times, takes about half as much. The remainder is widely scattered, and genuine imported Havana cigars are obtainable in all countries throughout the world. The total value of Cuba's yearly tobacco crop is from $40,000,000 to $50,000,000, including domestic consumption and foreign trade.
