The temperature was 65 degrees Fahr.

at night and 72 degrees during the day; dense clouds obscured the sun for many days, and the air was reeking with moisture.

In the evening it was always necessary to keep a blazing fire within the hut, as the floor and walls were wet and chilly.
The wet herbage disagreed with my baggage animals.
Innumerable flies appeared, including the tsetse, and in a few weeks the donkeys had no hair left, either on their ears or legs.

They drooped and died one by one.

It was in vain that I erected sheds and lighted fires; nothing would protect them from the flies.
