But there were able men among these colonists, and some things were done which were not foolish. Hariot, who had scientific knowledge, and was a careful observer, made notes of the products of the land, and became proficient in tobacco smoking; he also tested and approved the potato, and in other ways laid the foundation for a profitable export and import trade. John White, an artist, who afterward was put in charge of another colony, made drawings of the natives and their appurtenances, which still survive, and witness his fidelity and skill. Explorations up and down the coast, and for some distance inland, were made; the salubrity of the climate was eulogized, and it was admitted that the soil was of excellent fertility. In short, nothing was lacking, in the way of natural conditions, to make the colony a success; yet the Englishmen grew homesick and despondent, and longed to return to England and English women. The supplies which they were expecting from home had not arrived; and their situation was rendered somewhat precarious, by the growing hostility of the natives, who had come to the conclusion that these godlike white men were not persons with whom it was expedient for them to associate. At this juncture, down upon the coast suddenly swooped a fleet of over twenty sail with the English flag flying, and no less a personage than Sir Francis Drake in command. He was returning from a profitable pirating expedition against the Spaniards in the West Indies, and desired to see for himself how the colony sent out by his friend Raleigh was prospering. Out of his easily-got abundance he generously supplied the needs of the colonists, and presented them with a ship into the bargain, in which they might sail home should circumstances demand it. A couple of his most experienced officers, too, were added to the gift of the generous freebooter; and the outlook was now very different from what it had been a few days before. Yet fate was against them; or, to speak more accurately, they had lost the spirit which should animate pioneers, and when a touch of bad luck was added to their indisposition, they incontinently beat a retreat. A storm arose, which wrecked the ship that Drake had given them, and thus deprived them of the means of escape in case other disasters should arrive. They besought Drake to take them home with him; and he, with inexhaustible good humor, agreed to do so. His fleet, with the slack-souled colonists on board, had scarcely lost sight of the low shores of Roanoke, when the supply ship that had been so long awaited arrived with all the requisites for subduing the wilderness on board. She found the place deserted, and, putting about, sailed for home again. A fortnight later came Sir Richard Grenville with three ships more; and he, being of a persistent nature, would not consent to lose altogether the fruit of the efforts which had been made; he left fifteen of his men on the
