The shriek was followed by another, louder and yet more agonizing..for once started upon that journey, the hog never came back. One by one the men hooked up the hogs and slit their throats. There was a line of hogs with squeals and lifeblood ebbing away.. until at last each vanished into a huge vat of boiling water (some still alive). The hogs were so innocent. They came so very trustingly. They were so very human in their protests. They had done nothing to deserve it.
