Upstairs we set ourselves to astonish each other with gymnastic tours de force. Ilinka watched us with a faint smile of admiration, but refused an invitation to attempt a similar feat, saying that he had no strength.

Seriosha was extremely captivating. His face and eyes glowed with laughter as he surprised us with tricks which we had never seen before. He jumped over three chairs put together, turned somersaults right across the room, and finally stood on his head on a pyramid of Tatistchev’s dictionaries, moving his legs about with such comical rapidity that it was impossible not to help bursting with merriment.

After this last trick he pondered for a moment (blinking his eyes as usual), and then went up to Ilinka with a very serious face.
