CHAPTER II--THE MAD GOD

A small number of white men lived in Fort Yukon. These men had been long
in the country. They called themselves Sour-doughs, and took great pride
in so classifying themselves. For other men, new in the land, they felt
nothing but disdain. The men who came ashore from the steamers were
newcomers. They were known as _chechaquos_, and they always wilted at
the application of the name. They made their bread with baking-powder.
This was the invidious distinction between them and the Sour-doughs, who,
forsooth, made their bread from sour-dough because they had no baking-
powder.
