the best bows and arrows; the Amahuacas raise the best 
dogs and trade them to their neighbors. The Conebos and 
Shipibos are the best pottery makers in the whole Amazon 
valley and furnish supplies to all their neighbors...:. The 
women are the pottery makers and gather all the NES 
while the men do most of the trading. » (p. 94 ).. 
ls. e. p. 101: «The Collins Day -- Expedition left 
Philadelphia Christmas Day, 1914, and travelled by way of 
Molendo in Peru to La Paz in Bolivia. From La Paz the ex- 
pedition went to the headwaters of the Chapore aud descended 
this river into the Mamore, and thence proceeded down the 
Madeira and the Amazon. The main object of this interes- 
ting and successful expedition was the collection of natural 
history specimens. At the same time opportunities were 
found for collecting data relative to the Indian tribes on 
the Chapcre and the Mamore, especialiy the Yuracaras and 
the Joaquinanos. » 
1. s. e., vol. VII. pp. 210 ss: « The Indians of South 
America are physically so similar to those of North Ame- 
rica, and so unlike any other possible progenitors, that we 
must believe that their ancestors migrated across the Isth- 
mus of Panama in very early time. That migration ceased 
so long ago that little resemblance remains in the langua- 
ges or costums of the two continents. At the time of the 
Discovery a return migration was in progress. Indians from 
the Southern Continent were found passing over to dus is— 
lands of the West Indies. 
« When Columbus landed in the West Indies the peo- 
ple whom he found were the Arawaks and the Caribs. 
« The Arawaks, who were found trading from Cuba 
to the mainland of North America, can be traced through 
Venezuela, the Guianas, across the Amazon and the high-. 
lands of Brazil, to the Paraguay river: from there westward 
to the very foot of the Andes mountains. 
«The Caribs at the same time were pressing the 
Arawaks and were also beginning to occupy some of the 
islands of the Antilles. They, too, by means of their Jan- 
guage, can be traced southward to Central Brazil and west- 
ward about as far as the head waters of the Amazon. 
« The great Tupi stock, whose original home was in 
the very southern point of Brazil, pus! bed their way north- 
wards through other tribes of the uplands and around the 
three thousand miles of coast in the Amazon valley, thus 
coming into contact with the two other great stocks, and 
so mingling customs and cultures. 
« To the complications due to these great prehistoric 
migrations of peoples are added others of more recent date.»
