Most of the introductions I was fortunate enough to have came about, directly or indirectly, through letters written by Mary Lord and by Arturo Ramos, and I should like to thank these good friends first of all. I am grateful also to Lucha and Alfredo Porras in Lima, who put me up in the beginning and in the end put up with me; to Dorry and Ted Blacque, in La Paz; to Angela and Peter Deane in Buenos Aires; to Jean and Tony Deane in Punta del Este (Uruguay); to Nina and Clayton Templeton in Orizona (Brazil); to Señora and Señor Carlos Menendez Behety in Río Grande (Tierra del Fuego); and to Betsy and Oliver Bridges in Viamonte (Tierra del Fuego), all of whom, for no other reason than their own generosity, cheerfully took me in. The kind people who gave me supper here and a drink there are too numerous to list, but for kindness, advice and assistance, and incidental hospitality I am especially indebted to the following: Captain Geoffrey Davis, Mr. Deslandes, Brian Starmer, Derek Johnson, and Mike Williamson (M.S.Venimos); Harry Haddad (Belém); Jack Henderson, Wayne Snell, Joseph Hocking (Yarina Cocha); Andrés Porras, Celeste Allen, Señor Rafael Larco Hoyle, Sir Berkeley and Lady Gage, Madeleine Vuillemin, Anna and John Timoney, Mr.
