9 January: In the morning, clear sky, heavy frost, wind northwest. At eight o’clock, −20°F [−28.9°C]. The deaf-mute Mandan came into our room very early. The Hidatsa had slept in the fort. La Chevelure Levée—his name is actually [BíddaChóhki]—let himself be drawn, but it was too cold in the room and the work was soon stopped. The sun shone brightly about noon, but it was very cold. Because brushes and colors froze while painting, we had to keep warm water always [available]. At the same time, an intense fire burned in the fireplace. At twelve o’clock, −8°F [−22.2°C]. In the afternoon the Dacota came, and his drawing was completed. His name is Psíhdjä-Sáhpa. The evening was cold and calm.
