The trees on them are scraggy and wide apart.

There are also large open grass-covered spaces, with scarcely even a bush.

On these rather dreary intervals between the rivers it was impossible not to be painfully struck with the absence of all animal life.

Not a bird was to be seen, except occasionally a tomtit, some of the 'Sylviadae' and 'Drymoica', also a black bird ('Dicrurus Ludwigii', Smith) common throughout the country.

We were gladdened by the voice of birds only near the rivers, and there they are neither numerous nor varied.
