The oxen once upon a time sought to destroy the butchers, whopracticed a trade destructive to their race. They assembled on acertain day to carry out their purpose, and sharpened their hornsfor the contest. But one of them who was exceedingly old thus spoke: "These butchers, it istrue, slaughter1 us, but they do so with skillful hands, and withno unnecessary pain. if we get rid of them, we shall fall intothe hands of unskillful operators, and thus suffer a doubledeath: for you may be assured, that though all the butchersshould perish, yet will men never want beef." 
Do not be in a hurry to change one evil for another.
