In the third degree the symbolic allusions to the temple of Solomon, and the implements of Masonry employed in its construction, are extended and fully completed. At the building of that edifice, we have already seen that one class of the workmen was employed in the preparation of the materials, while another was engaged in placing those materials in their proper position. But there was a third and higher class,--the master workmen,--whose duty it was to superintend the two other classes, and to see that the stones were not only duly prepared, but that the most exact accuracy had been observed in giving to them their true juxtaposition in the edifice. It was then only that the last and finishing labor[63] was performed, and the cement was applied by these skilful workmen, to secure the materials in their appropriate places, and to unite the building in one enduring and connected mass. Hence the _trowel_, we are informed, was the most important, though of course not the only, implement in use among the master builders. They did not permit this last, indelible operation to be performed by any hands less skilful than their own. They required that the craftsmen should prove the correctness of their work by the square, level, and plumb, and test, by these unerring instruments, the accuracy of their joints; and, when satisfied of the just arrangement of every part, the cement, which was to give an unchangeable union to the whole, was then applied by themselves. Hence, in speculative Masonry, the trowel has been assigned to the third degree as its proper implement, and the symbolic meaning which accompanies it has a strict and beautiful reference to the purposes for which it was used in the ancient temple; for as it was there employed "to spread the cement which united the building in one common mass," so is it selected as the symbol of brotherly love--that cement whose object is to unite our mystic association in one sacred and harmonious band of brethren. Here, then, we perceive the first, or, as I have already called it, the elementary form of our symbolism--the adaptation of the terms, and implements, and processes of an operative art to a speculative science. The temple is now completed. The stones having been hewed, squared, and numbered in the quarries by the apprentices,--having been properly adjusted by the craftsmen, and finally secured in their appropriate places, with the strongest and purest cement, by the master builders,--the temple of King Solomon presented, in its finished condition, so noble an appearance of sublimity and grandeur as to well deserve to be selected, as it has been, for the type or symbol of that immortal temple of the body, to which Christ significantly and symbolically alluded when he said, "Destroy this temple, and in three days I will raise it up."
