"In our other talks, we have named the elements of each rock, and given some study to each. We have found that some of their elements are the basic elements of our own mortal frames--our bodies have a common earth-mother with these stones. "This last fact puts them in the Brotherhood--of Man." The seven hundred men showed their appreciation of the point made by prolonged applause. "Now I want to make clear to you that, although these rocks have different market values, are put to different uses, the real value for us this evening consists in the fact that each, in its own place, can yield a crystal equal in purity to the others.--Remember this the next time you go to work in the quarries and the sheds." He laid aside the specimens. "We had a talk last month about the guilds of four hundred years ago. I asked you then to look upon yourselves as members of a great twentieth century working guild. Have you done it? Has every man, who was present then, said since, when hewing a foundation stone, a block for a bridge abutment, a corner-stone for a cathedral or a railroad station, a cap-stone for a monument, a milestone, a lintel for a door, a hearthstone or a step for an altar, 'I belong to the great guild of the makers of this country; I quarry and hew the rock that lays the enduring bed for the iron or electric horses which rush from sea to sea and carry the burden of humanity'?--Think of it, men! Yours are the hands that make this great track of commerce possible. Yours are the hands that curve the stones, afterwards reared into noble arches beneath which the people assemble to do God reverence. Yours are the hands that square the deep foundations of the great bridges which, like the Brooklyn, cross high in mid-air from shore to shore! Have you said this? Have you done it?" "Ay, ay.--Sure.--We done it." The murmuring assent was polyglot. "Very well--see that you keep on doing it, and show that you do it by the good work you furnish." He motioned to the manipulators in the gallery to make ready for the stereopticon views. The blank blinding round played erratically on the curtain. The entire audience sat expectant. There was flashed upon the screen the interior of a Canadian "cabin." The family were at supper; the whole interior, simple and homely, was indicative of warmth and cheerful family life. The Canucks in the audience lost their heads. The clapping was frantic. Father Honore smiled. He tapped the portrayed wall with the end of his pointer. "This is comfort--no cold can penetrate these walls; they are double plastered. Credit limestone with that!" The audience showed its appreciation in no uncertain way. "The crystal--can any one see that--find that in this interior?"
