Barges and wherries plied up and down, the former often gaily canopied and propelled by livened oarsmen, all plying their arms in unison, so that the vessel looked like some brilliant many-limbed creature treading the water. Presently appeared the heavy walls inclosing the City itself, dominated by the tall openwork timber spire of Saint Paul's, with the four-square, four-turreted Tower acting, as it has been well said, as a padlock to a chain, and the river's breadth spanned by London bridge, a very street of houses built on the abutments. Now, Bankside had houses on each side of the road, and Wry-mouthed Tibble showed evident satisfaction when they turned to cross the bridge, where they had to ride in single file, not without some refractoriness on the part of young Headley's steed. On they went, now along streets where each story of the tall houses projected over the last, so that the gables seemed ready to meet; now beside walls of convent gardens, now past churches, while the country lads felt bewildered with the numbers passing to and fro, and the air was full of bells. Cap after cap was lifted in greeting to Master Headley by burgess, artisan, or apprentice, and many times did he draw Poppet's rein to exchange greetings and receive congratulations on his return. On reaching Saint Paul's Minster, he halted and bade the servants take home the horses, and tell the mistress, with his dutiful greetings, that he should be at home anon, and with guests. "We must een return thanks for our safe journey and great deliverance," he said to his young companions, and thrusting his arm into that of a russet-vested citizen, who met him at the door, he walked into the cathedral, recounting his adventure.
