Moseh took a deep breath and said, "O patient and noble Floor, concerned as you are with preventing the Pasha’s carpets from falling through into the cellar, no doubt you have scarce concerned yourself with anything so tedious and ignoble as long-term bathy-metric trends in the Guadalquivir Estuary. But, half-breed crypto-Jewish oar-slaves have much leisure to contemplate such matters—so, pray allow me to try your patience even further by informing you that there is a submerged sand-bar at the place where the Guadalquivir empties into the Gulf of Cadiz. For many years it has been the case that the treasure-galleons could pass this bar at high tide and enter the Guadalquivir and drop anchor before Sanlúcar de Barrameda, or Bonanza; or even sail fifty miles up the river to Seville. Those cities, then, were long the destinations of the treasure-fleet, and accordingly it is at Bonanza that the Viceroy, at the beginning of his reign, laid the cornerstone of a palace to receive the proceeds of his relentless, corrupt, and gluttonous pillagings. It has been a-building ever since, and is now complete. But the galleons have grown ever larger, and meanwhile Allah in His wisdom has decreed that the sand-bar I spoke of should wax, and build itself nearer to the surface. For these reasons, as of three years ago, the treasure-fleet no longer ends its journey in the mouth of the Guadalquivir, but at the magnificent deep-water bay of Cadiz, a few miles down the coast."
