Our conversation was suddenly terminated by one of my men running in to the tent with the bad news that one of the camels had dropped down and was dying. The report was too true. He was poisoned by a well-known plant that he had been caught in the act of eating. In a few hours he died. There is no more stupid animal than the camel. Nature has implanted in most animals an instinctive knowledge of the plants suitable for food, and they generally avoid those that are poisonous: but the camel will eat indiscriminately anything that is green; and if in a country where the plant exists that is well known by the Arabs as the "camel poison," watchers must always accompany the animals while grazing. The most fatal plant is a creeper, very succulent, and so beautifully green that its dense foliage is most attractive to the stupid victim. The stomach of the camel is very subject to inflammation, which is rapidly fatal. I have frequently seen them, after several days of sharp desert marching, arrive in good pasture, and die, within a few hours, of inflammation caused by repletion. It is extraordinary how they can exist upon the driest and apparently most innutritious food. When other animals are starving, the camel manages to pick up a subsistence, eating the ends of barren, leafless twigs, the dried sticks of certain shrubs, and the tough dry paper-like substance of the dome palm, about as succulent a breakfast as would be a green umbrella and a Times newspaper. With intense greediness the camel, although a hermit in simplicity of fare in hard times, feeds voraciously when in abundant pasture, always seeking the greenest shrubs. The poison-bush becomes a fatal bait. The camel is by no means well understood in Europe. Far from being the docile and patient animal generally described, it is quite the reverse, and the males are frequently dangerous. They are exceedingly perverse; and are, as before described, excessively stupid. For the great deserts they are wonderfully adapted, and without them it would be impossible to cross certain tracts of country for want of water.
