The proportion of storyed tower has a tendency to be lean and long with the times, among others the proportion of height (from footing to roof) to first-story, s span changes remarkably. With this change at outward form inside construction changes also. About the way of fabricating framework; since ancient tims, post Tokyo and eaves are fabricated in order. But in middle of mediaeval ages the new way that eaves is set up after post is set up on Tokyo directly is used at three-storyed tower. And in modorn times this way is used at five-storyed-tower also. The tower being constructed by this way has not always lean and long proportion. But I think this way has suited to construct the tower that has lean and long proportion, with various ways reinforcing fablication of post and Tokyo. At three-storyed tower since last ancient, the center-post is set up on the ceeling of first-story always, and there are many case that four-posts of interior are not set. But, at five-storyed tower the former exists only with the case primitted, and the latter does not at all. At three-storyed tower story is few as compared with five-storyed tower. All the more because easy-feeling exists on constructing tower, and so the new way of fabrication was used at three-storyed tower at first, I think.
