 " No. 26. A large pigweed extensively cultivated in the high plateaus 



of South America. The seeds are eaten, prepared in various ways. 

 Quinoa presents many color variations in the plants, as well as in the 

 seeds, especially in the direction of reds and purples. The colored seeds 

 are used almost exclusively for making cliiclia, or native beer. The 

 white seeds are preferred for eating, A possibility of utilizing the quinoa 

 in the United States lies in its use as a breakfast food. Some pronounce 

 it as good as oatmeal, and one resident Scotchman even insisted that it 

 was better ! From a crop stauvlpoint, too, the plant appears rather prom- 

 ising, being very vigorous and productive. It is of erect habit, has a 

 strong central stalk, and forms compact heads, heavy with seeds. There 

 is no reason why it shoukl not be gathered and thrashed by machii'.ery."
