True enough, in less than half an hour they had crossed a dike of solid masonry and were in the very heart of the great metropolis of the Netherlands--a walled city of ninety-five islands and nearly two hundred bridges. Although Ben had been there twice since his arrival in Holland, he saw much to excite wonder, but his Dutch comrades, having lived nearby all their lives, considered it the most matter-of-course place in the world. Everything interested Ben: the tall houses with their forked chimneys and gable ends facing the street; the merchants’ ware rooms, perched high up under the roofs of their dwellings, with long, armlike cranes hoisting and lowering goods past the household windows; the grand public buildings erected upon wooden piles driven deep into the marshy ground; the narrow streets; the canals crossing the city everywhere; the bridges; the locks; the various costumes; and, strangest of all, shops and dwellings crouching close to the fronts of the churches, sending their long, disproportionate chimneys far upward along the sacred walls. If he looked up, he saw tall, leaning houses, seeming to pierce the sky with their shining roofs. If he looked down, there was the queer street, without crossing or curb--nothing to separate the cobblestone pavement from the footpath of brick--and if he rested his eyes halfway, he saw complicated little mirrors (spionnen) fastened upon the outside of nearly every window, so arranged that the inmates of the houses could observe all that was going on in the street or inspect whoever might be knocking at the door, without being seen themselves. Sometimes a dogcart, heaped with wooden ware, passed him; then a donkey bearing a pair of panniers filled with crockery or glass; then a sled driven over the bare cobblestones (the runners kept greased with a dripping oil rag so that it might run easily); and then, perhaps, a showy but clumsy family carriage, drawn by the brownest of Flanders horses, swinging the whitest of snowy tails.
