It was a very different matter applying First Aid here from what it had been at the ambulance class in the gymnasium at the College. Except pocket-handkerchiefs, there were no materials of any kind to be had. Splints were an impossibility. Dorothy bound up the foot as well as she could, but her every touch was painful to her poor patient.

"You're sitting in such a wet place! Couldn't we lift you just a little?" she suggested.

"No; please leave me alone. Never mind the wet."

Gabrielle's rosy cheeks had grown very white. She looked almost ready to faint. The two boys turned to each other in desperation.

"We can't haul her up that chute with a broken ankle," said Percy. "I must go back to the Hydro. for help, and you must stay with her. I'll be as quick as I possibly can—I'll run all the way."

"Mind you don't tumble into any 'potholes', then," called Gabrielle anxiously, as he scrambled up the chasm and departed.

Then began a long, weary vigil of many interminable hours. The candles had burnt so low that the trio did not dare to have them all lighted together, in case they should be left in the dark before assistance came. They therefore used one at a time, and by its faint gleam the deep shadows of the rocks appeared more dim and gloomy than ever.

"It's almost like being buried alive!" shivered Gabrielle.

"I'm glad Alison didn't come with us," said Dorothy.

"We've landed ourselves in an uncommonly tight fix," remarked Eric.
