A large sum, amounting to several millions of francs, is voted every year for the protection of the shores of Flanders against the encroachments of the sea, by the construction of these solid embankments of brickwork and masonry, which will, in the course of a few years, extend in an unbroken line along the whole coast from end to end. The building of these massive sea-walls is a work of great labour and expense, for what seems to be an impregnable embankment, perhaps 30 feet high and 90 feet broad, solid and strong enough to resist the most violent breakers, will be undermined and fall to pieces in a few hours, if not made in the proper way. A _digue_, no matter how thick, which rests on the sand alone will not last. A thick bed of green branches bound together must first be laid down as a foundation: this is strengthened by posts driven through it into the sand. Heavy timbers, resting on bundles of branches lashed together, are wedged into the foundations, and slope inwards and upwards to within a few feet of the height to which it is intended to carry the _digue_. On the top another solid bed of branches is laid down, and the whole is first covered with concrete, and then with bricks or tiles, while the edge of the _digue_, at the top of the seaward slope, is composed of heavy blocks of stone cemented together and bound by iron rivets. _Digues_ made in this solid fashion, all of them higher above the shore than the Thames Embankment is above the river, and some of them broader than the Embankment, will, before very many years have passed, stretch along the whole coast of Flanders without a break, and will form not only a defence against the tides, but a huge level promenade, with the dunes on one side and the sea on the other. This is a gigantic undertaking, but it will be completed during the lifetime of the present generation. [Illustration: LA PANNE. A Flemish Inn--Playing Skittles.] Another grandiose idea, which is actually being carried into effect, is to connect all the seaside resorts on the coast of Flanders by a great boulevard, 40 yards wide, with a road for carriages and pedestrians, a track for motor-cars and bicycles, and an electric railway, all side by side. Large portions of this magnificent roadway, which is to be known as the 'Route Royale,' have already been completed between Blankenberghe and Ostend, and from Ostend to Plage de Westende. From Westende it will be continued to Nieuport-Bains, crossing the Yser by movable bridges, and thence to La Panne, and so onwards, winding through the dunes, over the French borders, and perhaps as far as Paris!
