Thus we know, from our own experience among modern workmen, who still pursue the same method, as well as from the traditions of the order, that the implements used in the quarries were few and simple, the work there requiring necessarily, indeed, but two tools, namely, the _twenty-four inch gauge_, or two foot rule, and the _common gavel_, or stone-cutter's hammer. With the former implement, the operative mason took the necessary dimensions of the stone he was about to prepare, and with the latter, by repeated blows, skilfully applied, he broke off every unnecessary protuberance, and rendered it smooth and square, and fit to take its place in the building. And thus, in the first degree of speculative Masonry, the Entered Apprentice receives these simple implements, as the emblematic working tools of his profession, with their appropriate symbolical instruction. To the operative mason their mechanical and practical use alone is signified, and nothing more of value does their presence convey to his mind. To the speculative Mason the sight of them is suggestive of far nobler and sublimer thoughts; they teach him to measure, not stones, but time; not to smooth and polish the marble for the builder's use, but to purify and cleanse his heart from every vice and imperfection that would render it unfit for a place in the spiritual temple of his body. In the symbolic alphabet of Freemasonry, therefore, the twenty-four inch gauge is a symbol of time well employed; the common gavel, of the purification of the heart. Here we may pause for a moment to refer to one of the coincidences between Freemasonry and those _Mysteries_[59] which formed so important a part of the ancient religions, and which coincidences have led the writers on this subject to the formation of a well-supported theory that there was a common connection between them. The coincidence to which I at present allude is this: in all these Mysteries--the incipient ceremony of initiation--the first step taken by the candidate was a lustration or purification. The aspirant was not permitted to enter the sacred vestibule, or take any part in the secret formula of initiation, until, by water or by fire, he was emblematically purified from the corruptions of the world which he was about to leave behind. I need not, after this, do more than suggest the similarity of this formula, in principle, to a corresponding one in Freemasonry, where the first symbols presented to the apprentice are those which inculcate a purification of the heart, of which the purification of the body in the ancient Mysteries was symbolic. We no longer use the bath or the fountain, because in our philosophical system the symbolization is more abstract, if I may use the term; but we present the aspirant with the _lamb-skin apron_, the _gauge_, and the _gavel_, as symbols of a spiritual purification. The design is the same, but the mode in which it is accomplished is different.
