Pg. 28 (KREMENTSCHUK):
   The inhabitants live almost entirely on flesh; it rarely (Pg. 29--ed.) happens that they have fish or vegetables to be served on their tables.  They have a kind of soup, however, which is made of groats and vegetables, of which they are very fond: this soup is rather sour, and is called borsch, from the name of the carrot which is boiled in it.
