There were seven variations in the arrangement of food in these boxes and they were numbered from 1 to 7, so that a different box could be used every day of the week. In addition to the food, each box contained a cake of soap, a piece of cheese-cloth, two boxes of matches, and a box of table salt. These tin boxes were lacquered to protect from rust and enclosed in wooden cases for transportation. A number in large type was printed on each. No. 1 was cased separately; Nos. 2 and 3, 4 and 5, 6 and 7 were cased together. For canoe travel the idea was to take these wooden cases off. I did not have an opportunity personally to experience the management of these food cases. We had sent them all ahead by pack-train for the explorers of the Dúvida River. The exploration of the Papagaio was decided upon during the march over the plateau of Matto Grosso and was accomplished with dependence upon native food only.
