The Crane, the Crow, and the Countryman

The authors of which are not known
A Crane and a Crow had made a league on oath, that the Crane should protect the Crow against the Birds, and that the Crow should foretell the future, so that the Crane might be on her guard. After this, on their frequently flying into the fields of a certain Countryman, and tearing up by the roots what had been sown, the owner of the field saw it, and being vexed, cried out: “Give me a stone, Boy, that I may hit the Crane.” When the Crow heard this, at once she warned the Crane, who took all due precaution. On another day, too, the Crow hearing him ask for a stone, again warned the Crane carefully to avoid the danger. The Countryman, suspecting that the divining Bird heard his commands, said to the Boy: “If I say, give me a cake, do you secretly hand me a stone.” The Crane came again; he bade the Boy give him a cake, but the Boy gave him a stone, with which he hit the Crane, and broke her legs. The Crane, on being wounded, said: “Prophetic Crow, where now are your auspices? Why did you not hasten to warn your companion, as you swore you would, that no such evil might befall me?” The Crow made answer: “It is not my art that deserves to be blamed; but the purposes of double-tongued people are so deceiving, who say one thing and do another.”
Those who impose upon the inexperienced by deceitful promises, fail not to cajole them by-and-bye with pretended reasons.
