Sigmaringen marks the lower limit of the series of rocky gorges into which the river plunges near Friedigen, and soon after leaving the town we came into a more pastoral region again, similar to that of our first day’s cruise. The flora changed somewhat, and fewer varieties of plants were noticeable. Alfred Parsons makes the following remarks in his botanical note-book: “Below Sigmaringen the meadow flora becomes more like that of England, but still with campanulas and purple sage; also occasionally a bright crimson dianthus with clusters of flowers. In an ash wood beneath which we camped was an undergrowth of _Spiræa aruncus_, all in bloom, five or six feet in height; in the wood also were Turk’s-cap lilies, Jacobs-ladder, tall, pale-yellow phyteuma, and commonly, near the river, gelder-rose bushes and clumps of forget-me-nots and white water-buttercups. The general impression of the flora is a greater prevalence of purple and blue flowers.” [Illustration: _Hohenzollern._] Frequent villages dot the hill-sides on either side of the broad, fertile valley, and the river begins to feel a new tyranny of man in the partial canalization of its channel. The current now increased in speed between the artificially straightened banks, and, counting the kilometre marks as we swept along, we found we were making seven and a half kilometres (nearly five miles) an hour without lifting a paddle. A more satisfactory mode of progression never fell to the lot of any traveller. Perfect summer weather, a comfortable canoe to lounge in, beautiful landscapes on all sides; [Illustration: NUNS AT RIEDLINGEN] and a vigorous current under the keel which gave an exhilarating sense of added strength, much like that felt when riding a spirited horse. Nothing more could be desired except, perhaps, unlimited time in which to enjoy such pleasant recreation. Haste was, indeed, a slight drawback to our enjoyment. We did not dare delay, for the season was already in its full prime, and we knew that the gales began in the lower river as early as the first week of September; besides, one of the party had only a limited number of weeks at his disposal. Under other circumstances we would have spent a day or more at Riedlingen, where we found most interesting architecture along the river-front and saw a party of nuns at work in a hay-field. We had a little more social success with them than we did with their coreligionists, the monks at Beuron, for they turned their great, cool, flapping head-dresses in our direction, and actually seemed temporarily interested in our canoes, and in us as well.
