The boys were surprised when Mr. Jally announced that it was supper
time and that he must go home.

"Gracious! And I told my aunt we'd be to supper by six o'clock!"
exclaimed Shep. "We'll have to leg it to her house."

"Come again to-morrow at nine o'clock," said the photographer, and
this the chums promised to do.

"Well, I've learned a whole lot to-day," said Snap as they walked
along. "I am sure I can take a much better picture than formerly."

"And I've learned one little lesson," came from Whopper. "After
this I am not going to take so many snapshots of landscapes. I am
going to take time exposures, and put my camera on a tripod, and
study the scene through the ground glass, to get the best view
possible."

Mrs. Carson, the doctor's sister, had given the boys their dinner,
and now she had supper on the table waiting for them. Their
experiments of the afternoon had made them hungry, and all
"pitched in" with a vigor that made the good woman smile.

"What do you intend to do this evening?" she asked.

"We are going to the circus, Aunt Jennie," answered Shep. "Father
said we might go."

"I thought as much. Don't stay out too late."
