Before the narrative which follows was placed in my hands, I had never seen Dr. Walter T. Goodwin, its author.

When the manuscript revealing his adventures among the pre-historic ruins of the Nan-Matal in the Carolines (The Moon Pool) had been given me by the International Association of Science for editing and revision to meet the requirements of a popular presentation, Dr. Goodwin had left America. He had explained that he was still too shaken, too depressed, to be able to recall experiences that must inevitably carry with them freshened memories of those whom he loved so well and from whom, he felt, he was separated in all probability forever.

I had understood that he had gone to some remote part of Asia to pursue certain botanical studies, and it was therefore with the liveliest surprise and interest that I received a summons from the President of the Association to meet Dr. Goodwin at a designated place and hour.

Through my close study of the Moon Pool papers I had formed a mental image of their writer. I had read, too, those volumes of botanical research which have set him high above all other American scientists in this field, gleaning from their curious mingling of extremely technical observations and minutely accurate but extraordinarily poetic descriptions, hints to amplify my picture of him. It gratified me to find I had drawn a pretty good one.

The man to whom the President of the Association introduced me was sturdy, well-knit, a little under average height. He had a broad but rather low forehead that reminded me somewhat of the late electrical wizard Steinmetz. Under level black brows shone eyes of clear hazel, kindly, shrewd, a little wistful, lightly humorous; the eyes both of a doer and a dreamer.
