Read it through once

The streets are roughly and badly paved with stone, and are tolerably crooked--enough so to make each street appear to close together constantly and come to an end about a hundred yards ahead of a pilgrim as long as he chooses to walk in it. Projecting from the top of the lower story of many of the houses is a very narrow porch-roof or shed, without supports from below; and I have several times seen cats jump across the street from one shed to the other when they were out calling. The cats could have jumped double the distance without extraordinary exertion. I mention these things to give an idea of how narrow the streets are. Since a cat can jump across them without the least inconvenience, it is hardly necessary to state that such streets are too narrow for carriages. These vehicles cannot navigate the Holy City.
