During the ten years of rebellion, the planters were able to protect their property by paying regular taxes to the Spanish Government, and at the same time allowing a certain amount to the insurgents, who agreed for this not to destroy the plantations. During this period they employed slave and coolie labour; but they were then subject to the Moret law, which was, in effect, that each planter should liberate a certain number of his slaves each year, and this was to continue until slavery had disappeared. Before this occurred, however, the treaty of Zanjon was made, whereby all slaves were liberated. By the Moret law, numbers were given to the slaves by the municipality, the name and number of the slave written on a slip, which was put in a box and each year ten per cent. of the names were drawn out. The owners were then officially notified that certain slaves, giving their numbers, were free, and this was published in a local paper. Most of these slaves remained with the planters. This law had a very good effect. Returning for a moment to the outbreak of the rebellion of 1868, it is necessary to refer to another sad page in the history of labour in Cuba; namely, the introduction of coolie labour from China. In 1869 the importation of slaves into Cuba was stopped, and then commenced the traffic in coolies, who were shipped from China, cargoes of them being landed at Havana. They were brought over under a contract for eight years by a company in Havana which had its own line of steamers. The contracts were sold to anyone who wished to buy them, at from four hundred to five hundred dollars per contract. The conditions of a contract were that the Chinaman was to serve for eight years. He was to be paid at the rate of four dollars per month, with rations, and was to receive two suits of clothes and a blanket. If ill for fifteen days, his wages were to be deducted and his time lost.
