§ 5. Special orders. Whenever any bill or other matter is made a
special order for a particular day, and it shall not be completed on
that day, it shall, unless otherwise ordered, retain its place on the
calendar as a special order in the order of business in which it was
considered. When a special order is under consideration, it shall take
precedence over any special order for a subsequent hour of the same day;
but such subsequent order may be taken up immediately after disposal of
the previous special order.
