Nothing can abide the taste of it but the jackass and his illegitimate child the mule.

But their testimony to its nutritiousness is worth nothing, for they will eat pine knots, or anthracite coal, or brass filings, or lead pipe, or old bottles, or anything that comes handy, and then go off looking as grateful as if they had had oysters for dinner.

Mules and donkeys and camels have appetites that anything will relieve temporarily, but nothing satisfy.
In Syria, once, at the head-waters of the Jordan, a camel took charge of my overcoat while the tents were being pitched, and examined it with a critical eye, all over, with as much interest as if he had an idea of getting one made like it; and then, after he was done figuring on it as an article of apparel, he began to contemplate it as an article of diet.
He put his foot on it, and lifted one of the sleeves out with his teeth, and chewed and chewed at it, gradually taking it in, and all the while opening and closing his eyes in a kind of religious ecstasy, as if he had never tasted anything as good as an overcoat before, in his life.

Then he smacked his lips once or twice, and reached after the other sleeve.
Next he tried the velvet collar, and smiled a smile of such contentment that it was plain to see that he regarded that as the daintiest thing about an overcoat.

The tails went next, along with some percussion caps and cough candy, and some fig-paste from Constantinople.
