It is so bad, my friend, to live in Paris without a crust of a black bread...
From the letter, written by Sheremetyev to Pushkin
The third Spas (falls on the 29 of August) was called Nuts Spas or Grain Spas. It was called Nut Spas due to the fact that by this time nuts were usually ripe, and Grain Spas because it symbolized the end of the harvest-time.
This holiday was usually celebrated by baking a round loaf of new yield. In ancient times Russian people used to say "The Third Spas brought us bread".
