Still, Ike's explanation of furnishing the man with a daily lunch looked plausible.
"Hold on," called Ralph after the receding form.
"What is it?" inquired the tramp, wheeling about.
"I'll help you out—wait a minute."
Ralph hurried to his locker. Fully half of his noonday lunch had been left untasted. He bundled up the fragments and returned to the break in the wall.
"Here's a bite," said Ralph.
"Thank you," growled the tramp gruffly, taking the proffered lunch.
A minute later Ralph was summoned to a bench placed under the windows at the south curve of the building.
Limpy stood on the bench, looking out.
"Come here," he directed. "No use!"
"What do you mean?" inquired Ralph.
"Look."
Ralph, clambering up to the bench, had the retiring tramp in full view.
The latter was piece by piece firing the lunch he had given him at switches and signal posts, as if he had a special spite against it.
"Didn't come for food, you see?" observed the helper.
