Explanation:

These strangers have arrive to our shore. I warned my brother and told the chief to come take a look. They are strange. I have never seen anything like this. It appears as if they are giant white seabirds or floating islands. Their skin is a different color, very pale. Their hair is the color of fresh ripe corn. In the distance there is something remarkably large swimming, or floating on the water, and I've never seen this before. They immediately returning to the shore apprised their countrymen of what they had seen, and pressed them to go out with them and discover what it might be.
