To the quote:

What grass did Leo Nikolaevich Tolstoy cut before writing the next passage?

The telegram was from my wife. Her signature with a blue pencil, "Anna", came first into his eyes.
...
Peter, stop the car. I’m going to St. Petersburg,” he said to the lace."

Two points are drawn to attention here. First, it is unclear where the signature of the blue pencil on the _telegram_ came from. Second, the character asking to stop the car sits in the hotel room."

I explain to the fools:
1) The telegrams are called so because they were transmitted by telegraph, using the Morse alphabet. The device issued either a long strip with points-tyre to be deciphered, or, if it was a writing telegraph (in 1839 such appeared) - a twist recorded in blue color. Seismographs still paint in blue, you can see.
2) "Stop the car" is the order of the lackey to run out on the street and catch the pitcher.
