The edition I read growing up was one of the ones that missed out that chapter, so it was very interesting to me when I first read it. The Wind in the Willows is out of copyright and available for free on Gutenberg, incidentally.I like the idea of Constantinople-based trader rats.
‘You are not one of US,’ said the Water Rat, ‘nor yet a farmer; nor even, I should judge, of this country.’
‘Right,’ replied the stranger. ‘I’m a seafaring rat, I am, and the port I originally hail from is Constantinople, though I’m a sort of a foreigner there too, in a manner of speaking. You will have heard of Constantinople, friend? A fair city, and an ancient and glorious one. And you may have heard, too, of Sigurd, King of Norway, and how he sailed thither with sixty ships, and how he and his men rode up through streets all canopied in their honour with purple and gold; and how the Emperor and Empress came down and banqueted with him on board his ship. When Sigurd returned home, many of his Northmen remained behind and entered the Emperor’s body-guard, and my ancestor, a Norwegian born, stayed behind too, with the ships that Sigurd gave the Emperor. Seafarers we have ever been, and no wonder; as for me, the city of my birth is no more my home than any pleasant port between there and the London River. I know them all, and they know me. Set me down on any of their quays or foreshores, and I am home again.’
