This is William Bradford's 'From History of Plymouth Plantation' written in 1650. He was a Governor of the colony for 35 years. This is his personal journal. The full texts are found here but I have chosen to concentrate on this particular extract.
How they sought a place of habitation (1620)
Being thus arrived at Cape Cod the 11th of November, and necessity calling them to look out a place for habitation (as well as the master's and mariner's importunity); they having brought a large shallop with them out of England, stowed in quarters in the ship, they now got her out and set their carpenters to work to trim her up; but being much bruised and shattered in the ship with foul weather, they saw she would be long in mending. Whereupon a few of them tendered themselves to go by land and discover those nearest places, whilst the shallop was in mending; and the rather because as they went into that harbor there seemed to be an opening some two or three leagues off, which the master judged to be a river. It was conceived there might be some danger in the attempt, yet seeing them resolute, they were permitted to go, being sixteen of them well armed under the conduct of Captain Standish, having such instructions given them as was thought meet.
They set forth the 15 of November; and when they had marched about the space of a mile by the seaside, they espied five or six persons with a dog coming towards them, who were savages; but they fled from them and ran up into the woods, and the English followed them, partly to see if they could speak with them, and partly to discover if there might not be more of them lying in ambush. But the Indians seeing themselves thus followed, they again forsook the woods and ran away on the sands as hard as they could, so as they could not come near them but followed them by the track of their feet sundry miles and saw that they had come the same way. So, night coming on, they made their rendezvous and set out their sentinels, and rested in quiet that night; and the next morning followed their track till they had headed a great creek and so left the sands, and turned another way into the woods. But they still followed them by guess, hoping to find their dwellings; but they soon lost both them and themselves, falling into such thickets as were ready to tear their clothes and armor in pieces; but were most distressed for want of drink. But at length they found water and refreshed themselves, being the first New England water they drunk of, and was now in great thirst as pleasant unto them as wine or beer had been in foretimes.
Afterwards, they directed their course to come to the other shore, for they knew it was a neck of land they were to cross over, and so at length got to the seaside and marched to this supposed river, and by the way found a pond of clear, fresh water, and shortly after a good quantity of clear ground where the Indians had formerly set corn, and some of their graves. And proceeding further they saw new stubble where corn had been set the same year; also they found where lately a house had been, where some planks and a great kettle was remaining, and heaps of sand newly paddled with their hands. Which, they digging up, found in them divers fair Indian baskets filled with corn, and some in ears, fair and good, of divers colors, which seemed to them a very goodly sight (having never seen any such before). This was near the place of that supposed river they came to seek, unto which they went and found it to open itself into two arms with a high cliff of sand in the entrance but more like to be creeks of salt water than any fresh, for aught they saw; and that there was good harborage for their shallop, leaving it further to be discovered by their shallop, when she was ready. So, their time limited them being expired, they returned to the ship lest they should be in fear of their safety; and took with them part of the corn and buried up the rest. And so, like the men from Eshcol, carried with them of the fruits of the land and showed their brethren; of which, and their return, they were marvelously glad and their hearts encouraged.
After this, the shallop being got ready, they set out again for the better discovery of this place, and the master of the ship desired to go himself. So there went some thirty men but found it to be no harbor for ships but only for boats. There was also found two of their houses covered with mats, and sundry of their implements in them, but the people were run away and could not be seen. Also there was found more of their corn and of their beans of various colors; the corn and beans they brought away, purposing to give them full satisfaction when they should meet with any of them as, about some six months afterward they did, to their good content.
And here is to be noted a special providence of God, and a great mercy to this poor people, that here they got seed to plant them corn the next year, or else they might have starved, for they had none nor any likelihood to get any till the season had been past, as the sequel did manifest. Neither is it likely they had had this, if the first voyage had not been made, for the ground was now all covered with snow and hard frozen; but the Lord is never wanting unto His in their greatest needs; let His holy name have all the praise. . . .
One quote I have highlighted talks about the first contact with The Native Americans, Bradford calls The Natives 'savages' and says there may be 'more of them lying in ambush', this shows how The Settlers had preconceived notions of The Natives that sway their judgement. It is particularly interesting when focusing on other parts of the journal where Bradford describes The Settlers finding houses and crops. These are indications of civilisation and not of a savage lifestyle, however, he doesn't note that this is the case. Bradford notes how The Settlers 'might have starved' if they had not 'got seed to plant them corn the next year'. He attributes the finding of the seeds to god instead of to The Natives from whom The Settlers stole the seeds. This is another representation of the attitude towards the natives that was adopted in early colonial America as well as a strong emphasis on religion. Without the Native's help the Settlers would have starved and yet they are not willing to acknowledge it.
The extract also demonstrates the idea of America as a haven. When the men drink the New England water for the first time it is said to be as 'pleasant unto them as wine or beer had been in foretimes'. This gives the reader a sense of America being better than England and possibly encourage them to emigrate.
