The Wolf and the Crane
He who expects a recompense for his services from the dishonest commits a twofold mistake; first, because he assists the undeserving, and in the next place, because he cannot be gone while he is yet safe.
A bone that he had swallowed stuck in the jaws of a Wolf. Thereupon, overcome by extreme pain, he began to tempt all and sundry by great rewards to extract the cause of misery. At length, on his taking an oath, a Crane was prevailed on, and, trusting the length of her neck to his throat, she wrought, with danger to herself, a cure for the Wolf. When she demanded the promised reward for this service, “You are an ungrateful one,” replied the Wolf, “to have taken your head in safety out of my mouth, and then to ask for a reward.”
