During tliree years of regular correspondenee with my friend Pro- 
fessor Lafone Quevedo, I liave learnt much of the general bearing of 
these unknown Chaco languages upon the wider lield of South Ameri- 
can lingüistica, and through his many hints and suggestions, and con- 
stant encouragcment to tlirow out my feelers into the Quechua and 
Mojo particularly, I venture in this work to compare and weave into 
my net some of the beauties of Andean type. 
He generously disclaims the thanks that I would gladly offer for all 
his help in revisión of ideas and conclusions, for the translation into 
Spanish of the Grammar, and for his excellent introduction to this 
work, all of which he declares malee for scientiiic truth for wliich we 
both earnestly seelc.
