In June 1923, Hemingway took Hadley, with Robert McAlmon and Bird, to Spain where he found a new passion with his first visits to the bullfights. During the summer he wrote five new vignettes (chapters 12–16), all about bullfighting, finishing the last two on his return to Paris in August. That summer he also honed new narrative techniques in chapters 7–11. In August he reported to Pound that he was about to begin the last two pieces (chapters 17 and 18), implemented revisions that Pound suggested, and sent the manuscript to Bill Bird. Then he left Paris with Hadley (who was pregnant with their first child) for Toronto, where he was living when Bird finished producing the book.
