Whoever it was--and the form certainly did resemble Dave's--he made no reply, but hurried through the yard down into the street.
"Somebody else, I suppose!" murmured Bart. "Wonder what he wanted! Perhaps it was one of the fishermen who wanted to leave something for father. Can't stop to see now."
He hurried to the top of the hill, raised his glass, and pointed it toward the lighthouse.
"Father!" he said, appearing the next minute in the kitchen, and speaking hurriedly, "oh--oh--come here! and you--granny--and see if--"
He said no more, for this was sufficient to startle his auditors, and all three hastened up the hill.
"You didn't see a second light at the lighthouse?" asked the father.
"Yes, I did," replied Bart; "I know I did."
"Guess you were mistaken," suggested granny.
"No, I wasn't; you just look and see your--yourself."
Granny could not see anything except a hazy glow where the lighthouse might be supposed to stand.
