At Koobe there was such a mass of mud in the pond, worked up by the wallowing rhinoceros to the consistency of mortar, that only by great labor could we get a space cleared at one side for the water to ooze through and collect in for the oxen.

Should the rhinoceros come back, a single roll in the great mass we had thrown on one side would have rendered all our labor vain.

It was therefore necessary for us to guard the spot at night.

On these great flats all around we saw in the white sultry glare herds of zebras, gnus, and occasionally buffaloes, standing for days, looking wistfully toward the wells for a share of the nasty water.

It is mere wanton cruelty to take advantage of the necessities of these poor animals, and shoot them down one after another, without intending to make the smallest use of either the flesh, skins, or horns.
