I wish to thank Chief Gustavo Melendez of the Sharanahua community of Gastabala for giving us permission to stay in Gastabala and for his hospitality during that time. I also wish to thank the people of Gastabala who taught us their language with great patience, and demonstrated great friendliness and concern for our well-being and safety. I am especially grateful to Eusebio, our most dedicated language teacher, and companion on our exploratory trip up the Quebrada E.
I wish to thank the Summer Institute of Linguistics' fieldworkers among the Sharanahua, Gene and Marie Scott, for their friendship and hospitality during the time we shared in Gastabala. Their willingness to share of their wealth of knowledge from four decades of work in the region was much appreciated.
Finally I wish to thank Paul Johnson, Scott Welsh , and his wife Nicole, of Pioneer Mission for their willingness to discuss their activities in the Alto Purús region with us.
