All hearings hereinbefore provided to be heard before the chancellor may be heard before a special commissioner who may be appointed by the chancellor, who shall have full authority to make all findings of law and of fact, and whose findings shall be reduced to writing and reported to the chancellor for confirmation either in term-time or in vacation. Such reports shall be subject to exceptions or objections, but no notice of the hearing of such exceptions shall be necessary, provided the date for hearing exceptions to the commissioner’s report shall have been fixed in the order referring the matter to the commissioner. Such commissioner shall receive such compensation as may be allowed him by the chancellor.
