Off the coast of Chile

"It happened one day, about noon, going towards my boat, I was exceedingly surprised with the print of a man's naked foot on the shore, which was very plain to be seen in the sand.  I stood like one thunderstruck, or as if I had seen an apparition;  I listened, I looked round me, but I could hear nothing, nor see anything; I went up to a rising ground, to look farther; I went up the shore and down the shore, but it was all one;  I could see no other impression but that one."
