Denton and the ice-cream arrived simultaneously. Shortly afterwards a warning whistle was blown. A small pandemonium of singing and delighted squealing was heard from the upper deck. Evan stuck close to Denton. They remained on the lower deck while the gangplank was drawn in and the ropes cast off. Meanwhile Evan was gathering what further information he could.
"How often do you make these trips?"
"Twice a week—Tuesdays and Saturdays."
"What is the Ozone Association? I never heard of it."
"I can't tell you much, though I work for them. I've always understood it was some rich man who wished to keep his name out of the thing. I was hired by a law firm to manage the trips, and the money comes to me through them."
"How did you get hold of all your helpers?"
"Oh, one way and another. Miss Playfair gets her friends to help."
When the Ernestina finally moved out into the stream, Denton remained below, attending to the stowage of the ice-cream and to other matters, and Evan stayed with him. To tell the truth, he dreaded a little to put his fortunes to the touch by venturing up above. They were unpacking sandwiches when Denton suddenly said:
"Here's Anway. Anway, here's a friend of yours."
Evan looked up with a wary smile. As it chanced, the busy Denton was called from another direction at that moment, and he did not see the actual meeting between the two. Evan had his back to the light and Anway did not instantly recognise him. Anway's expression graduated from expectancy at the sound of the word friend to blankness as he failed to recognise Evan, and to something like consternation when he did.
