It is amusing to see the precision with which the children's congress breaks up into its various sections. The most popular and important is that of the engineers. The little members come toddling down from the cliffs with a load of implements, shouldering rake and spade, and dangling tiny buckets from their arms. One little group makes straight for its sand-hole of yesterday, and is soon busy with huge heaps and mounds which are to take the form of a castle. A crowing little urchin beside is already waving the Union Jack which is ready to crown the edifice, if the Fates ever suffer it to be crowned. Engineers of less military taste are busy near the water's edge with an elaborate system of reservoirs and canals, and greeting with shouts of triumph the admission of the water to miniature little harbours. A corps of absolutely unscientific labourers are simply engaged in digging the deepest hole they can, and the blue nets over their sunshades are alone visible above the edge of the excavation. It is delightful to watch the industry, the energy, the absolute seriousness and conviction of the engineers. Sentries warn you off from the limits of the fortress; you are politely asked to "please take care," as your clumsy foot strays along the delicate brink of the canal. Suggestions that have a mechanical turn about them, hints on the best way of reaching the water or the possibility of a steeper slope for the sand-walls, are listened to with attention and respect. You are rewarded by an invitation which allows you to witness the very moment when the dyke is broken and the sea admitted into basin and canal, or the yet more ecstatic moment when the Union Jack waves over the completed castle.
