Passage adapted from Gulliver's Travels by Jonathan Swift (1726)

About four hours after we began our journey, I awaked by a very ridiculous accident; for the carriage being stopped a while, to adjust something that was out of order, two or three of the young natives had the curiosity to see how I looked when I was asleep; they climbed up into the engine, and advancing very softly to my face, one of them, an officer in the guards, put the sharp end of his half–pike a good way up into my left nostril, which tickled my nose like a straw, and made me sneeze violently; whereupon they stole off unperceived, and it was three weeks before I knew the cause of my waking so suddenly. We made a long march the remaining part of the day, and, rested at night with five hundred guards on each side of me, half with torches, and half with bows and arrows, ready to shoot me if I should offer to stir. The next morning at sun–rise we continued our march, and arrived within two hundred yards of the city gates about noon. The emperor, and all his court, came out to meet us; but his great officers would by no means suffer his majesty to endanger his person by mounting on my body.

At the place where the carriage stopped there stood an ancient temple, esteemed to be the largest in the whole kingdom; which, having been polluted some years before by an unnatural murder, was, according to the zeal of those people, looked upon as profane, and therefore had been applied to common use, and all the ornaments and furniture carried away. In this edifice it was determined I should lodge. The great gate fronting to the north was about four feet high, and almost two feet wide, through which I could easily creep. On each side of the gate was a small window, not above six inches from the ground: into that on the left side, the king's smith conveyed fourscore and eleven chains, like those that hang to a lady's watch in Europe, and almost as large, which were locked to my left leg with six–and–thirty padlocks. Over against this temple, on the other side of the great highway, at twenty feet distance, there was a turret at least five feet high. Here the emperor ascended, with many principal lords of his court, to have an opportunity of viewing me, as I was told, for I could not see them. It was reckoned that above a hundred thousand inhabitants came out of the town upon the same errand; and, in spite of my guards, I believe there could not be fewer than ten thousand at several times, who mounted my body by the help of ladders. But a proclamation was soon issued, to forbid it upon pain of death. When the workmen found it was impossible for me to break loose, they cut all the strings that bound me; whereupon I rose up, with as melancholy a disposition as ever I had in my life. But the noise and astonishment of the people, at seeing me rise and walk, are not to be expressed. The chains that held my left leg were about two yards long, and gave me not only the liberty of walking backwards and forwards in a semicircle, but, being fixed within four inches of the gate, allowed me to creep in, and lie at my full length in the temple.

When I found myself on my feet, I looked about me, and must confess I never beheld a more entertaining prospect. The country around appeared like a continued garden, and the enclosed fields, which were generally forty feet square, resembled so many beds of flowers. These fields were intermingled with woods of half a stang, and the tallest trees, as I could judge, appeared to be seven feet high. I viewed the town on my left hand, which looked like the painted scene of a city in a theatre.

I had been for some hours extremely pressed by the necessities of nature; which was no wonder, it being almost two days since I had last disburdened myself. I was under great difficulties between urgency and shame. The best expedient I could think of, was to creep into my house, which I accordingly did; and shutting the gate after me, I went as far as the length of my chain would suffer, and discharged my body of that uneasy load. But this was the only time I was ever guilty of so uncleanly an action; for which I cannot but hope the candid reader will give some allowance, after he has maturely and impartially considered my case, and the distress I was in. From this time my constant practice was, as soon as I rose, to perform that business in open air, at the full extent of my chain; and due care was taken every morning before company came, that the offensive matter should be carried off in wheel–barrows, by two servants appointed for that purpose. I would not have dwelt so long upon a circumstance that, perhaps, at first sight, may appear not very momentous, if I had not thought it necessary to justify my character, in point of cleanliness, to the world; which, I am told, some of my maligners have been pleased, upon this and other occasions, to call in question.

What does the bolded and underlined word "necessities" most nearly mean?

Adapted from "Walter Raleigh" by Wilbur F. Gordy (1917)

[Raleigh] therefore fitted out two vessels, which were to sail to the land north of Florida, then occupied by Spain, and bring back reports of the country. The captains of these vessels arrived in Pamlico Sound, and landed on an island, which they found rich in grapes and woods and abounding in deer and other game. The explorers received kind treatment from the Indians, two of whom accompanied the voyagers to England on their return. Queen Elizabeth was so pleased with the good reports from the new country that she called it Virginia in honor of herself—the Virgin Queen.

The next year, 1585, Raleigh sent out to Virginia seven vessels and one hundred colonists, under his cousin, Sir Richard Grenville, and Ralph Lane. They landed on Roanoke Island, and made a settlement there, but the colony was not prosperous. At the outset, by unwise and cruel treatment they made enemies of the natives. It is related that, an Indian having stolen a silver cup from one of the colonists, the Englishmen burned an entire village and ruined the corn belonging to its people. Such punishment was out of all proportion to the petty offence. It is not surprising, therefore, that from that time the settlers found the Indians unfriendly.

Very soon Grenville sailed back to England, leaving the colony in charge of Ralph Lane. The colonists instead of building houses and tilling the soil to supply food, were bent upon finding gold. Hence they listened with eager interest to a story that the Indians told of the Roanoke River. According to this story, the river flowed out of a fountain in a rock so near the ocean that in time of storm the waves dashed over into the fountain. The river, the Indians said, flowed near rich mines of gold and silver, in a country where there was a town with walls made of pearls. Lane and his followers foolishly started up the river in a vain search for this wonderful land. They encountered many difficulties, including hostile attacks by Indians, and suffered so much from lack of food that they had to eat the flesh of their own dogs.

The discovery of the tobacco plant introduced into England the custom of smoking, and a curious story is told of it in connection with Sir Walter Raleigh, who soon learned to smoke. One day his servant, who knew nothing of the new custom, came into his master’s room and found him smoking from a silver pipe. Believing Raleigh was on fire, the faithful servant hastily dashed a mug of ale at him to quench the flames and rescue him from death.

The wealth that lay hidden in the soil was yet , and no one felt any enthusiasm over the new colony of Virginia. Most men would by this time have lost hope. But Raleigh was not daunted. Two years later he made a second attempt to plant a colony in the New World, this time sending over three ships, with a hundred and fifty settlers, including seventeen women. John White was appointed governor of the colony. These settlers had the forethought to carry with them farming implements to use in tilling the soil. When they landed on Roanoke Island they found no trace of the fifteen men left there two years before by Sir Richard Grenville. The new settlers had not been on the island long before they were in need of help from England, and begged Governor White to return home for provisions and more settlers. White at first refused to leave them, but finally consented. A warm interest in the feeble settlement and love for his little granddaughter, born soon after the settlers arrived, persuaded him to yield. This little girl, the first white girl born in America, was named after the new country, Virginia, her full name being Virginia Dare.

When Governor White left the settlement he expected to return immediately, but upon reaching England he found his countrymen greatly excited over the coming invasion of the much-dreaded “Spanish Armada.“ Everybody was astir, and Raleigh was aroused to his fullest energy in preparation to meet the hated foe.

But, notwithstanding this, he found time to fit out two small vessels for Governor White. Although they sailed, trouble with the Spaniards compelled their return to England, and not until two years later, when he Spanish Armada had been defeated, did Governor White sail again for Virginia, this time as a passenger in a West Indianan. He landed on Roanoke Island as before, but there remained of the settlement only some chests of books, some maps, and some firearms, all of which had been ruined by the Indians.

Upon bidding Governor White farewell, the colonists had agreed to carve on a tree the name of the place to which they would go if they should decide to leave Roanoke Island. They were also to carve above the name a cross if they were in serious trouble. Governor White found the word CROATOAN cut in capital letters on a large tree, but he found no cross. Before White could sail to Croatian, which was an island not far away, he had to return to England because the captain of the vessel, having encountered stormy weather, refused to sail further. What became of the lost colonists is still a mystery. It is possible, that the Indians either killed them or captured and enslaved them.

Raleigh sent out other expeditions in search of the lost colony, but without success. He had already spent a sum equal to more than a million dollars in trying to plant this colony, and now felt that he must give up all hope of accomplishing his purpose.
