Drawing inside the hall of my deserted shelter, I once more consulted the grocery boy's map with the aid of the flashlight. The immediate problem was how to reach the ancient railway; and I now saw that the safest course was ahead to Babson Street; then west to Lafayette—there edging around but not crossing an open space homologous to the one I had traversed—and subsequently back northward and westward in a zigzagging line through Lafayette, Bates, Adam, and Bank streets—the latter skirting the river gorge—to the abandoned and dilapidated station I had seen from my window. My reason for going ahead to Babson was that I wished neither to recross the earlier open space nor to begin my westward course along a cross street as broad as South.
