Missouri shall be admitted into this Union on an equal footing with the
original states, in all respects whatever. To this resolution there is a
condition, which having been fulfilled, it is now useless here to repeat.

at St. Louis, on Monday the 12th of June, 1820, and continued by

Missouri.'"

qualifications as the governor. Art. 4, s. 14. He is by virtue of his office
president of the senate, and when the office of governor becomes vacant by
death, resignation, absence from the state, removal from office, refusal to
qualify, or otherwise, the lieutenant-governor possesses all the powers and
