The Trivia Situation, Part 43

Each day for the next few weeks I will be giving away a volume of the Harvard Classics from a complete set dating back to 1910. Here’s how it works. I’m going to ask a question relating to the volume in question. If you think you know that answer, email it to thewholefivefeet AT gmail DOT com. You will have until five o’clock Eastern time to respond. I will then randomly select the winner from among one of the correct answers, and that winner will get the book.

Here is today’s question on Volume 43: American Historical Documents.  What explorer was the first European to land at mainland North America, claiming it for England?

I will announce today’s winner tomorrow, at the same time that I pose tomorrow’s question.
