106 Katie Summers, tide being low, Katie, Fanny, and the rest took their spades and went on to the sands, and fine fun they had. Harry and Tom, with the help of their sisters, built a castle of sand, and made a thick wall round it, and a trench beyond that, and then they fetched water in their little buckets and filled the trench. When it was all finished it was a very grand affair indeed. Then they played at soldiers, and one party was to try and take the castle from the other, and there was great shouting and laughing and fun over this, but it ended in the castle being knocked to pieces. Not that that mattered much, as Katie said, when little Lucy began to cry about it; for if they had not broken it down, the waves would have done it when the tide came up, and they could easily build up another to-morrow.
