At first in order to press the juice out of the cane the same means were employed as for the grinding of wheat. They were cylinders set in motion by mules or oxen, a process in which half of the juice was wasted. At the beginning of the eighteenth century a more efficacious process was employed in imitation of that which was in use in Hayti. Not until the government itself took the initiative and encouraged the use of implements and machines that had proved of advantage in other sugar-raising colonies, was a change gradually effected. The great planter and landowner of Havana, D. Nicolas Calvo de la Puerta, was the man through whose influence and insistence upon certain innovations the sugar production was slowly improved. Finally there was the problem of converting the guarapo or fermented cane juice into sugar, which was at first also very primitive and slowly yielded to more productive and profitable methods. Lastly the sugar production of the island developed another product, which was not only popular on the island, but became an article of exportation. From 1760 to 1767 Havana, which was the only port qualified to export sweetmeats, sent out annually thirteen thousand cases of sixteen arrobas each. In the period of five years from 1791 to 1795 inclusive, the export was 7,572,600 arrobas. White sugar was then worth thirty-two reals per arroba, brown sugar twenty-eight. The French immigrants from Santo Domingo were an element that contributed to the improvement and promotion of the sugar industry.

Though they furnished a far smaller proportion of the island's wealth, hides, cane, brandy, refined honey and wax also began to figure in the economic records of Cuba. Wax became a valuable product about the year 1764 when Bishop Morell brought a few swarms of bees from his Florida exile. It was exported to the ports of the Gulf of Mexico where it was highly esteemed for its superior quality. The indigo plant which was introduced during the administration of Governor Las Casas proved in time a new source of Cuban wealth. Coffee plantations and cocoa groves had also multiplied in number, and were slowly furnishing new products for home consumption as for exportation.

The following figures will give a limited but reliable survey of the growth of agriculture towards the end of the century. Before the year 1761 there were only between sixty and seventy sugar refineries on the island. By the end of the century there were four hundred and eighty. Before the year 1796 there were only eight or ten coffee plantations, so that the island barely produced enough coffee for its own consumption. By the end of the century there were three hundred and twenty-six "cafeyeres." At the same time the island had two thousand four hundred and thirty-nine vegas, or tobacco fields, and one thousand two hundred and twenty-three colmenares or apiaries. The revenues of the island from 1793, when they amounted to over one million pesos, rose steadily until at the beginning of the century they were about three million pesos annually. The sugar plantations yielded great profits, but they also required big investments of money and labor. One of the most prominent sugar planters on the island, D. José Ignacio Echegoyen, calculated that to produce ten thousand arrobas of sugar, an expenditure of twelve thousand seven hundred and sixty-seven pesos was needed, besides a capital of sixty thousand. He was one of the foremost citizens that protested against the tax of one tenth on sugar. Work on the sugar plantations was the hardest imaginable; even the negro slaves could not stand it longer than ten years. Then their working capacity was completely exhausted and they were given their liberty.

Though the importation of negro slaves essentially helped the development of agriculture and the industries connected with it, there still existed restrictions and regulations which acted as a continual check upon the growth of the population, and had a paralyzing effect upon the intellectual development of the colonists. A favorable solution of these important questions offered great obstacles. Although the principles on which Spain founded her restrictive system had been relaxed, there existed a great number of interests that had been created through this system and were unwilling to give up their privileges. Derogation of these restrictions would have meant loss and injury to some peninsular subjects that had grown rich and powerful through them.

The historian Guiteras elucidates this point when he says that higher state reasons, supported by the right that, according to the notions of the epoch gave them the international law and the famous bull of Alexander VI. and was sustained by a great and expensive war against the nations that attempted to colonize America, had influenced the conduct of the government for nearly three centuries. The government only agreed by force of invincible circumstances to have the British and the French establish themselves in and continue in possession of a part of North America and a few islands of the Antilles; but it always insisted on maintaining the vast possessions that recognized its authority closed to the commerce of the allies according to the agreement. With the existence of a new and independent nation near these states, whose political organization, religious principles and national character were diametrically opposed to those of the Spanish government, these possessions and dominions of the crown seemed to be in danger. The imprudent demonstration in the state of Georgia had already shown the spirit of hostility which when the republic of the United States was barely established began to manifest itself against the neighboring possessions of a country which in her diplomatic relations had from the beginning of the Revolution always showed herself friendly. Such considerations very likely increased the aversion of the monarch as of his court towards Britain and the British race, in whose favor they had yielded more than to any other power concessions demanded by the interests of their subjects in America.

These were some of the great impediments which the champions of progress encountered in their valiant endeavors to free the economic development of Cuba and to help its much hampered industries. But one of the most serious obstacles was the restriction of Spanish and especially foreign immigration.

It seems that these restrictions which dated from the accession of Philip II. had two definite objects; the first was to preserve the purity of the Spanish stock in the West Indies and other possessions of Spanish America; the second was to prevent foreigners from learning the extent and the resources of Spain's American colonies. Edward Gaylord Bourne says in "Spain in America":

"In regard to Spaniards, the policy adopted was one of restriction and rigid supervision. No one, either native or foreigner, was allowed to go to the Indies without a permit from the crown (or in some cases from the Casa de Contracion) under penalty of forfeiting his property. Officers of the fleets or vessels were held strictly responsible for infractions of this rule. In the code the details of these restrictions are amplified in seventy-three laws. The reasons for such strict regulations covering emigration was to protect the Indies from being overrun with idle and turbulent adventurers anxious only 'to get rich quickly and not content with food and clothing, which every moderately industrious man was assured of.'"

Another reason for this strict supervision is given in a law enacted in the year 1602, which directs the deportation of foreigners from the ports of the Indies, because "the ports are not safe in the things of our holy Catholic faith, and great care should be taken that no error creep in among the Indians." An exception to the rule was made twenty years later, when expert mechanics were allowed, but traders in the cities remained excluded. So rigidly was this policy upheld that Humboldt during five years of travel in Spanish America met only one German resident.

It is more difficult to understand the object of this policy than to realize its effect upon the country's growth and progress. M. Masse says in his book "L'Isle de Cuba et la Havane":
