The structural connexion of all the mighty, magnificent buildings throughout these ten miles was the grand conception of Rameses the Great, of which I spoke some way back. There never were, we may be quite sure, ten such miles, elsewhere, on the surface of this earth. It is rash to prophesy, but we may doubt whether there ever will be ten such miles again. We may, I think, say there will not be, unless time give birth to two conditions. The first of the two is, that communities should become animated with the desire to do for themselves what these mighty Pharaohs did for themselves in the old days of their greatness; and as man is much the same now that he was then, and as private persons are capable of entertaining the same ideas as kings, there is no _à priori_ reason against the possibility of this. The second condition is, that machinery should eventually give us the power of cutting and moving large blocks of stone at a far cheaper rate than is possible, with that already mighty assistant, at present. For, as the world does not go back, we may be sure that myriads of captives, and of helpless subjects, will never again be employed in this way. It is quite conceivable that the mass of some community may come to feel itself great, the feeling being in the community generally, and not only in the individual at its head; and should they at the same time entertain the desire that the magnificence of their architecture should be in proportion to, and express, the greatness of their ideas and sentiments, then the world may again see hypostyle halls as grand as that of Karnak, and magnificence equal to that of the Osirid Court of the Rameseum: with, however, the difference that they will be constructed by, and for, the community. In this there would be no injury in any way to any one, and there would be nothing to regret, for those who had raised such structures, and were in the habit of using them, would perhaps on that account be less likely to be mean, and little, in the ordinary occurrences of life. At all events there would be nothing demoralizing in making machinery the slave to do the heavy drudgery required in their construction. * * * * *
