The work and observation of a professional American woman author, this diary tells of six weeks spent on the great Sahara desert in 1961 on what amounted to a part scientific- part adventurous expedition to the remote country of Chad. The party consisted of Catherine Collins, and her husband; the woman who shared both the authorship and the arduous trip, Miggs Pomeroy, and her husband; Randolph Churchill and his son; an American scientist; and seven British soldiers. Travelling over the sands in Land-Rovers the party variously hunted desert mice, encountered wandering tribesmen, ate fantastic meals of beans and champagne; found abandoned wreckage from the desert campaigns of World War II; and finally reached the isolated Chad far down in the Tibesti Mountains. Notes on the voyagers themselves and their misadventures verge on the precious, but observations of native life and the terrain of North Africa prove valuable and informative. Probably will appeal most to women readers---especially those with an urge for travel adventure.
