The diameterof each pier is 23^ in.; and their horizontal section is some-thing of the form shown at b. The height of the masonry overthe crown of each arch is 2 ft. Now, in 13 ft. there are 156 in., which, divided by 6, gives26 in. for the diameter of each pillar: but the diameter is 23^ in.,therefore 2^ in. too small; consequently, each pier requires thereduction of 1 ft. 3 in. in the height, taken from the dimensionsof the span; thus leaving 11 ft. 9 in. for the balancing height of 374- Principles of Construction65. the piers: but the piers are 11 ft. 6 in. As their proportionsapproach so near to each other, it is probable that a mistakemight have been made in the measurement of the diameter, byhaving allowed a trifle too much. The above proportions ex-actly coincide with those required for arches and piers runningin a single series, as in Hartlip Church. In the Lady Chapel, it has been stated that several seriesof arches and piers cross each other at right angles; therefore,according to the experiment fig. 158., Vol. III. p. 418., theywill, thus circumstanced, carry double the weight of a singleseries. The architects were fully aware of this, and availed them-selves of it to give lightness and beauty to the structure, whichthey have admirably accomplished by the concave section up thefour sides of every pillar.
