We’re tired. Tolya and I try to be restrained. In the morning we continued preparing for the experiment with the equipment installed on the cargo ship. Many operations in the experiment methodology haven’t been timed. We’re losing time clarifying the documentation and demanding explanations for how to perform operations.

Today I photographed Lake Victoria in Africa. Nothing remarkable. A flat lake of uniform blue water with ragged, irregularly shaped, gently sloping shores. All around is flat terrain covered with reed jungles of yellowish-brown color, and to the right and left — elongated north-to-south lakes 100 to 200 kilometers long — Tanganyika and Rudolf. In their water shades, shape, and surrounding terrain they’re more picturesque. In Africa, in its central part, an enormous number of smoke plumes are visible — impossible even to count. Hundreds of smoke trails stand there, as if all the chimneys on Earth had been assembled. Though many of them, I know, aren’t fires but bonfires from the burning of giant grass thickets by inhabitants before planting; here they even call it elephant grass.
