"Show them, by all means," said the head ghost, and then the girls knew they were in for it.

They had heard of initiations before and what ridiculous things the girls and boys who were lucky or unlucky enough to be initiated had to go through with. But in every case they had heard of the clubs and fraternities had been human ones. The initiation into a ghost club was sure to be much worse.

The leader of the ghost club raised her hand again, and three girls sprang forward from the group behind her. Before the girls knew what was happening to them they found their hands pinned behind them while huge sheets were flung over their heads.

The girls that were doing all this to them tied something that felt like ropes around their waists, pulled the sheets into shape and the girls found to their great relief that there were eye and nose and mouth holes similar to those in the strange robes worn by the ghosts themselves.

After that they went through strange and weird experiences that they remembered in their dreams for a long time afterward.

They were taught the "shiver salute," bandages were tied over their eyes, or rather eye holes, and queer, slimy crawly things were pressed into their hands.

They were forced to swallow things that felt like particularly fat and squirmy worms. It was no wonder that the stomachs of the girls threatened to turn inside out. Several times they were on the point of revolt, but always they choked back protests and did as they were told. For to have come so near being members of the secret society of Three Towers and then to lose out at the last minute because they had not nerve enough to go through with the initiation, would have been real tragedy. So they gritted their teeth and went ahead.

At last it was over, the bandages were taken off their eyes, and they were led before the head ghost to take the final oath of allegiance when a strange thing happened.

Billie, happening to glance through the trees to the bright patch of lawn beyond, uttered a startled cry. For across that bright patch of lawn a man was running, crouched and furtive.

"Girls!" she cried, forgetting the club, forgetting everything but this new and startling fact. "Look! Quick! Here, through the trees!"
