Read it through once

We wished to go aloft. The sacristan showed us a marble stairway (of course it was marble, and of the purest and whitest--there is no other stone, no brick, no wood, among its building materials) and told us to go up one hundred and eighty-two steps and stop till he came. It was not necessary to say stop--we should have done that any how. We were tired by the time we got there. This was the roof. Here, springing from its broad marble flagstones, were the long files of spires, looking very tall close at hand, but diminishing in the distance like the pipes of an organ. We could see now that the statue on the top of each was the size of a large man, though they all looked like dolls from the street. We could see, also, that from the inside of each and every one of these hollow spires, from sixteen to thirty-one beautiful marble statues looked out upon the world below.
