"I don't believe that I shall ever be as high up as that, with the blue beneath me, like I've always wanted!" reflected the young girl, dolefully looking up. "I believe that last night in my dream is all the flying I'm ever going to have had!"

And again that longing took her. That pure longing to be high; above the Law that clogs the children of Man to the Earth from which he came. To feel the unfettered air above and below and about her all at once!... But what could she do to gratify the impulse even a little?

Only one thing.

She might climb.

The idea with which she started off on her mad prank was to climb up to that iron lattice of lacework; to run up that as a sailor climbs the rope-ladders of his masts, and thence from the very highest peak attainable to look down on London, even as last night she had looked down on it from her dream.

Her start was not in the open air at all, but from the bottom of the scaffolding inside, where it was all beams and uprights and floors of planks. It reminded Gwenna of being underneath the old wooden pier at Aberdovey, and looking up. She went up ladders, through trap-doors, walked over wooden floors to other ladders until she got up to the last trap-door and through it out of the shadow and the stuffiness to the sunshine and the fresh air again. She stood on the top platform of the gantry which supported that engine and the wheels that worked (she supposed) the iron lattice that was still far above her head.

Presently she would climb that. She knew that she could. She was never afraid of heights. Her head was steady enough. Her feet in their brown shoes were as sure as the feet of the tiny sheep that picked their way up the rocky steeps of her Welsh mountains. She could climb as well as any of the men ... but for the moment she rested, standing by the platform hand-railing, breathing in the freshened breeze.

The birds of the City—pigeons and sparrows—were taking their short flights far beneath her perch. All London was spread below her, as it had been in that flying dream, and with as strong a sense of security as in the dream she looked down upon it.

There, between the forests of chimney-pots, gleamed that highway of the Thames, blue-grey now as it reflected the sky, winding out of the distance that meant the clean, green country and the willows below the lawns where people had danced; flowing on into London that sullied it, and burdened it with her barges, and spanned it with her bridges, but could not stay it; on and out its waters passed towards Greenwich and the Docks and the tall ships and the North Sea!

And there on its bank was the office, the dwindled yard from which Gwenna had started. The men returning....
