for winter use) were accustomed to save a portion 

 of the Bread-root harvest, first slicing the tubers 

 and then drying them in the sun or over a slow 

 tire. The dried article was ground between stones 

 and added to stews or soups, or mixed with water 

 and baked in the form of cakes. The heart of the 

 tuber is white and granular, and, according to an 

 analysis quoted hj Dr. Havard,^ contains 70% 

 starch, 9% nitrogenous matter and 5% sugar. Some 

 attempts have been made to introduce it into culti- 

 vation as a rival of the potato, but the latter is so 

 well entrenched in the popular regard that nothing 

 has come of the effort. As a resource for those 

 who are cut off from a potato supply, however, this 

 free offering of Nature should be better known. 

 John Colter, one of Lewis and Clarke's men, escap-
