 " 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 w T ell as in the 

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

 are used almost exclusively for making chicha, 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 standpoint, 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 should not be gathered and thrashed by machinery."

 " No. 19. Oca. A plant related to our common sheep sorrel, widely

 are an important article of food. Ocas are eaten raw, as well as cooked, 

 and are also frozen and dried. Raw ocas, when first dug, have a dis- 

 tinctly acid taste, like sheep sorrel, but this is lost after the tubers have 

 been exposed to the sun. The plant attains a height of 1 foot or more 

 and has the general appearance of a large sheep sorrel. The flowers are 

 yellow and the leaflets are folded at night or in wet weather, the same
