Freezing hard all day, 4 degrees of frost minimum; very dull with dirty brown mist, treacherous underfoot. In morning to buy vegetables; met Mr.Costella. To get groceries in afternoon. Then tramped all over Wimbledon and Raynes Park to get food for cats. Finally bought a tin of Kit-E-Kat in Raynes Park which the animals will not eat. Met Dorothy and Mabel Longhurst under the skew arch at the station. I improved winding gear of gramophone.
