There is frost even as far as the Chobe, and a partial winter in the Barotse valley, but beyond the Orange River we never have cold and damp combined.

Indeed, a shower of rain seldom or never falls during winter, and hence the healthiness of the Bechuana climate.

From the Barotse valley northward it is questionable if it ever freezes; but, during the prevalence of the south wind, the thermometer sinks as low as 42 Deg., and conveys the impression of bitter cold.
Nothing can exceed the beauty of the change from the wintry appearance to that of spring at Kolobeng.

Previous to the commencement of the rains, an easterly wind blows strongly by day, but dies away at night.
The clouds collect in increasing masses, and relieve in some measure the bright glare of the southern sun.

The wind dries up every thing, and when at its greatest strength is hot, and raises clouds of dust.
The general temperature during the day rises above 96 Deg.: then showers begin to fall; and if the ground is but once well soaked with a good day's rain, the change produced is marvelous.
