Each morning in summer the boats go, loaded with fruit and vegetables, to the "floating market" of Amiens (_photo below_). The soil of these gardens is wonderfully fertile, fruit and vegetable crops succeeding one another unceasingly all the year round. The total revenue exceeds two million francs, and a "hectare" (rather less than two and a half acres) often costs twelve thousand francs. [Illustration: THE "FLOATING" MARKET _Place Parmentier. In the background "Pont de la Dodane."_] [Illustration: THE RUE DU DON ON MARKET-DAY.] The St. Leu Quarter _Return by the same way to the bridge, then turn to the right and follow the Port d'Amont as far as the first bridge_ (Pont du Cange). This bridge dates from the fifteenth century, and is the oldest of the many bridges which cross the canals. _Cross the bridge, then turn to the left into the Rue Belu, which runs along the river-side. From here there is_ a pretty =view= of the Cathedral and the old town (_photo below_). _At the end of the Rue Belu, cross the Pont de la Dodane. To the left is the Place Parmentier, where the_ "Floating Market" _is held (p. 51). In front are the first houses of the curious_ Rue du Don, _seen in the centre of the photo below, and on the right of the photo on p. 53._ _Take a few steps to get a good view of this street (photo above), re-cross the Pont de la Dodane, then take on the left the Rue d' Engoulvent, which runs by the side of an arm of the Somme (photo p. 53), as far as the_ =church of St. Leu=. _The tourist may either go round the apsis of the_ church, _taking on the left the small Rue St. Leu which crosses the arm of the river, or continue straight ahead as far as the Rue St. Leu, via the Rue Graineville, which is the continuation of the Rue d'Engoulvent_. [Illustration: _To the right_, PONT DE LA DODANE. _In the background, Place Parmentier entrance to the Rue du Don._] =St. Leu Church= (hist. mon.) has undergone important alterations at various times. One of its façades is 15th century, and a steeple was rebuilt in the 16th century, in the Gothic style. A shell splinter [Illustration: OLD BISHOPS' PALACE (_in front of Cathedral_). _To the right_, RUE DU DON.] broke the mullions and stained glass of one of the windows of the apse (north side). This Church is in the centre of the old quarter or lower part of the city. It is there that the commerce and industry of the town have been centralised since the Middle Ages. A maze of narrow, winding streets crossed by innumerable canals or arms of the Somme river, connected by bridges, forms this part of the town. Numerous small water-falls supply motive power to the local factories and works. Formerly, the workshops of the fullers and dyers, which crowded the banks of the canals, and where the cloth-fulling and woad-grinding were done, were driven by water-wheels (_see p. 2_).
