intercourse in the interior.[263] The Gauchos of central Uruguay speak Spanish with harsh rough accents. They change _y_ and _ll_ into the French _j_.[264] Whitney and Waitz thought that all American languages proceeded from a single original one. Powell thought that they were "many languages, belonging to distinct families, which have no apparent unity of origin."[265] Evidence is adduced, however, that "the same aboriginal peoples who named the waters of North America coined also the prehistoric geographical titles in South America."[266] The Finns and Samoyeds are, from the standpoint of language, practically the same race. The two tongues present the highest development of the agglutinative process of the Ural-Altaic languages.[267] +139. Taking up and dropping languages.+ The way in which languages are taken up or dropped is also perplexing. Keane[268] gives a list of peoples who have dropped one language and taken up another; he also gives a list of those who have changed physical type but have retained the same language. Holub[269] mentions the Makololo, who have almost entirely disappeared, but their language has passed to their conquerors. It became necessary to the latter from the spread of their dominion and from their closer intercourse with the peoples south of the Zambesi, on account of which, "without any intentional interference by the rulers, a common and easily understood language showed itself indispensable." Almost every village in New Guinea has its own language, and it is said that in New Britain people who live thirty miles apart cannot understand each other.[270] +140. Pigeon dialects.+ The Germans find themselves at a disadvantage in dealing with aborigines because they have no dialect like pigeon English or the Coast Malay used by the Dutch.[271] Many examples are given, from the Baltic region, of peasant dialects made in sport by subjecting all words to the same modification.[272] Our own children often do this to English in order to make a secret language.
