It is not without signification that practically all district-maps of this date mark the courses of rivers, but not of roads. Probably few records could be found of any touring of this period worth calling a tour which was not partly conducted by river. One advantage of river travel was that that way was more regularly practicable than the roads, which bad weather soon rendered barely passable. Moreover, it was the pleasantest mode of journeying, especially if the boat was towed; for travelling in a sixteenth-century waggon produced something like sea-sickness in those unaccustomed to it. On the other hand, to get the benefit of the cheapness of river travelling, as compared with riding, one had to wait, at times, for fellow-travellers to fill the boat; also, the choice of route was, of course, more limited; and on the swifter rivers it was not usual, or worth while, to attempt an up-stream journey. On the Loire, for instance, at Roanne, where it began to be navigable, boats were all built for sale, not for hire, as they were not expected to come back; and the same practice was in use elsewhere. But this must be taken as a rule with many exceptions. On the lower Loire towing was in regular use and Lady Fanshawe, who tried it, right from Nantes to Orleans, says, "of all my travels none were, for travel sake, as I may call it, so pleasant as this." They went on shore to sleep, but kept to the boat all daytime, for it possessed a "hearth," a charcoal fire on which they did the cooking. Where towing was most frequently used was probably Russia, all by hand; sometimes as many as three hundred men were being employed at once by Charles II's ambassador for the six barges and one boat between Archangel and Vologda. When rowing was to be done, the tourist found himself expected, practically compelled, to take his share on the Elbe and the Rhine, and often on other rivers too. The diarist Evelyn reckoned that he rowed twenty leagues of the distance between Roanne and Orleans, and no doubt Edmund Waller, the poet, did the same, as he was one of the party. If any exemptions were made, it was the boatman who exempted himself.
