A man was wont to spare his horse and put the burden upon the back of his burro. Ailing somewhat the burro one day asked the horse to relieve him of part of the load. "If you will take your fair share I shall get well again."
The horse told him to get along with his complaints. So the burro jogged on until he dropped. Then, the man came up, loosed the load from the burro and putting it on the horse, made him carry the body of the dead burro also.
"Alas! For my ill nature," cried the horse, "by not bearing my just share of the load I must now carry all of it, with a dead weight into the bargain."
