The noise came from the depth of the brush, and for the moment Bob could not make out what it was.
“Maybe somebody is following me,” he thought.
A minute later the sound ceased. Bob listened for it quite a while, but at last turned again to his work. It was no easy matter to get a good picture, as the sun shone almost directly toward him.
“If I am not careful, I’ll have a ghost on the plate,” he said to himself, thereby meaning that the sun would cause the picture to be white spotted.
To make sure of getting a perfect plate Bob took two pictures, one while the sun was out full and the other when that luminary was slightly clouded.
The pictures taken, Bob placed them away so that no light might reach them, and prepared to leave the spot.
“That makes picture number one,” he thought. “And I sincerely hope that it proves a success.”
He resolved to develop both plates as soon as he reached the wagon, and if one was not perfect in every way to return and try again.
Bob had just started to close up his camera when the strange noise he had heard before reached his ears.
This time it came closer, and the young photographer made up his mind it was some animal roaming in the brush.
