Soon after the departure of Perestrello, the attention of Zarco and Vaz was strongly excited by observing certain clouds or vapours at a great distance in the ocean, which continually presented the same aspect, and preserved exactly the same bearing from Puerto Santo, and at length occasioned a conjecture, that the appearance might proceed from land in that quarter. Gonsalvo and Vaz accordingly put to sea and sailed towards the suspected land, and soon discovered that the appearances which had attracted their notice actually proceeded from a considerable island entirely overgrown with wood, to which, on that account, they gave the name of Madeira[5]. After bestowing considerable attention upon the soil and other circumstances of this island, which was utterly destitute of inhabitants, Gonzalvo and Vaz returned to Portugal with the welcome intelligence, and gave so favourable a report of the extent, fertility, and salubrity of Madeira, that Don Henry determined to colonize and cultivate it. Accordingly, with the consent of the king of Portugal, the island of Madeira was bestowed in hereditary property upon Zarco and Vaz; one division named _Funchal_ being given to Zarco, and the other moiety, named _Machico_, to Vaz. In the year 1420 Zarco began the plantation of Madeira, and being much impeded in his progress by the immense quantity of thick and tall trees, with which it was then everywhere encumbered, he set the wood on fire to facilitate the clearing of the surface for cultivation. The wood is reported to have continued burning for seven years[6], and so great was the devastation as to occasion great inconvenience to the colony for many years afterwards, from the want of timber. Don Henry appears to have been a prince of most uncommonly enlarged and liberal views; not only capable of devising the means of making maritime discoveries, which had never been thought of before his time, but of estimating their value when made, and of applying them to purposes the most useful and important for his country. Reflecting upon the reported fertility of the soil, and the excellence of the climate of Madeira, and comparing both with the judicious foresight of a philosopher, politician, and naturalist, in reference to the most valuable productions of similar climates and soils, he wisely conceived, and successfully executed the idea of introducing the cultivation of sugar and wines into this new colony; For these purposes, Portugal would readily supply him with vines; and with people conversant in their management: But he had to procure sugar canes, and persons experienced in their cultivation, and in the process of manufacturing sugar from their juice, from the island of Sicily, into which that article of culture had been introduced by the Arabs.
