What is tail assembly?

Famous quotes containing the words assembly and/or tail:

    A man may be a heretic in the truth; and if he believe things only because his pastor says so, or the assembly so determines, without knowing other reason, though his belief be true, yet the very truth he holds becomes his heresy.
    John Milton (1608–1674)

    And now he comes again with clatter of stone,
    And mounts the wall again with whited eyes
    And all his tail that isn’t hair up straight.
    Robert Frost (1874–1963)
