Mr. Syme's latest in his series of biographies of famous explorers and settlers recreates Balboa's life in the familiar succinct manner that deftly captures much of the urgency and drama as well as personal elements that marked the events. Placing Balboa's particular role in the opening of America in a clearly indicated continuum, Mr. Syme sets the stage with the first Columbus voyages and the particular combination of motives-for riches and for progress- in Balboa which caused him to go to the new world too. The smoothly related events which followed- Balboa's first trip to the Pearl Coast, the struggle with the wicked Enciso over leadership in San Sebastian, the final settlement of Darien, the expedition of discovery and the treachery which ended it all for Balboa- have their fascination. And, taken in their own perspective, there is an accurate realism both in the narrative and in William Stobbs rough but capable drawing.
