I'm going to go with Natelson on this one:

I got this information from his book The Original Constitution:

The first procedure began with two-thirds of the House and two-thirds of the Senate concurring on a proposed amendment. The idea behind allowing Congress to initiate amendments was that Congress, by reason of its familiarity with the day-to-day workings of the government, would be more likely to perceive the need for reform than would the states.[672] The wording of Article V (“shall deem it necessary”) made it clear that the decision to propose an amendment was within the absolute discretion of Congress.

Congress also would decide whether the amendment should be ratified by state legislatures or conventions. If Congress selected state legislatures, Congress sent its proposal to them for ratification. If three-quarters of the legislatures ratified it, the amendment became part of the Constitution.

The second procedure was the same as the first, except that Congress elected to send its proposal to state ratifying conventions. If three-quarters of the conventions agreed, the amendment would become part of the Constitution.

The third and fourth options contemplated state legislatures applying to Congress for a new convention for the limited purpose of proposing amendments. If two-thirds of all state legislatures agreed on the substance of the application, Congress was to call such a convention. If the convention proposed one or more amendments, then Congress would decide whether ratification would be by state legislatures (third option) or state conventions (fourth option). Approval by three-quarters of the state legislatures or conventions was needed for ratification.
