I wonder how many readers advised you that the “Red Sea” south of Kadesh Barnea is really the Persian Gulf? (Cover, April 26.)

THE EDITOR REPLIES: Thank you so much, Mr. Eisen, but the map is correct. The map on last week’s cover shows two arms of the Red Sea; the Persian Gulf is farther east. We also thank you for allowing us to fix an error that we did make.

The map we used came from “The Picture-Book History of the Jews” by Howard and Bette Fast, published by the Hebrew Publishing Company on 79 Delancey Street on Manhattan’s Lower East Side in 1942. The labeling error was the Fasts’; the lack of acknowledgement of the art source last week was ours, and for that we apologize.
