Still, except for very unusual occa-sions, the suspension principle is hardly practicable ; nor in any casedoes it seem to offer any corresponding facility in bridging openings inwalls that -we have postulated as one of the requirements of a construc-tion that can aspire to be the basis of a style. The cantilever principle, on the other hand, does, I think, fulfilboth the requirements. It is capable of satisfactorily covering areas,and also of bridging openings, while, as distinct essentially from both 224 THE CANTILEVER E\ ARCHITECTURE.

The principle of the cantilever, to put it paradoxically, is that youcan double the strength of a beam by cutting it in two. In Fig. I, for instance, we see a beam, say, twenty feet long, ca-pable of sustaining, say, ten thousand pounds. If, now, the beam besawed in two, at A and K, the middle piece, being only half the lengthof the whole beam, will sustain twice the load,—in this case, twenty THE CANTILEVER IN ARCHITECTURE. thousand pounds. The end pieces also are each capable of sustainingten thousand, each its share of the load of the middle piece. True,they could not for a moment stand, as they are shown in Fig. i ; they
