Were some of my youthful friends with me, they would find many things that would please them very much. Particularly, they would like to share with me the pleasure of throwing out crumbs to the pigeons, which have followed us two or three thousand miles, to pick up whatever is thrown them. They are very pretty creatures; their bodies are white, and their wings spotted with black. The manner of measuring the distance we advance is amusing. I will attempt to describe it. They have a glass, shaped like an hour-glass, filled with sand, which will run out in fourteen seconds.

A knot is tied at certain distances in the cord, and as many knots as run off, while the sand is running in the glass, so many miles the ship sails in an hour.
