The rest of the way is hilly, without anything steep. PLACES OF INTEREST ON THE ROUTE This section of the route is chiefly through the forest country adjoining Les Landes. =Tartas.=--A little town on the Midouze with a few towers of its early fortifications left standing. =Dax= (_just off the road to the left_).--Has hot mineral springs, which were known to the Romans, and is still a small bathing-place. =St. Géours-de-Marenne.=--A roadside hamlet with a semi-fortified church. =St. Vincent-de-Tyrosse.=--The same, with a modern church. =Bayonne.=--A large fortified town on the Adour, the scene of much fighting in the Peninsular War. (1) Cathedral, built when the town belonged to the English, dates from 1213, and the cloisters from 1240; the west end is the latest portion; (2) the Château Vieux, an imposing building of twelfth to fifteenth century date, now barracks. =Biarritz.=--A very attractive watering-place of recent growth; rocky promontory, with slight remains of thirteenth-century castle, picturesque coves and harbours, and a spray-drenched statue of the Virgin. When one leaves Mont-de-Marsan the road is still through forest, and for mile after mile the dark pines shut out the views. The marshy district of Les Landes, where the shepherds use stilts in getting over the wet places, lies to the north-west. The traffic on the roads, with the exception of automobiles, is drawn either by bullocks or mules, with their heads yoked together in a wooden framework, in addition to their collars. A horse is rarely seen. After passing the village of Campagne the road twists through the little town of Tartas, where there remain two towers of the fortifications dismantled by the order of Louis XIII. In the sixteenth century Tartas was one of the principal strongholds of the Protestants in Gascony. The church is modern. After crossing the bridge over the Midouze the turning to the left is taken. One then goes to the right and to the left at the fork.
