round.

In one scene Ruth had to discover the hidden soldier. Then she had to
steal out to him with food. Later, at night, she was to help him to
escape. Then, a week later, she was to go out to the same shed and
discover a letter he had hidden in the hay. That ended the scenes at
the shed, and it could be taken away to make room for something else.

"Oh, Ruth, you did that splendidly!" exclaimed Alice, as her sister
finished her work and went up on the shady porch to rest.

"Did you like it? I'm glad."

"Like it? It was great! Where you discovered that letter in the hay,
your face showed such natural surprise."

"I'm glad it didn't register merriment."

"Why?"

"Because, as I picked up the letter, I found a big blot of the yellow
from the hens' eggs on it. I hope it doesn't show in the picture. I had
all I could do to keep from laughing when I thought of Mr. Switzer in
the omelet scene."

"Oh, well, you know they want all white stuff yellow when they make
pictures."

"In the studio, but not outdoors."

This is a fact. As the scenes in the studio are taken in the glare of a
special kind of electric light, all white objects, even the collars and
cuffs of the men, are yellow in tone, though in the picture they show
perfectly white. This is due to the chemical rays of the lights used.
Out of doors, under sunlight, colors are seen in their own hues.

"You did very well in that funny little scene with Paul," said Ruth to
her sister.

"You mean in the swing under the apple tree?"

"Yes."

"I was so afraid he would swing me too high," Alice went on. "He was
cutting up so. I told him to stop, but he wouldn't."

"It was very natural. I think it will show well. Hark! what's that?"
cried Ruth, leaping to her feet.

"Thunder," suggested Alice, as a distant, rumbling noise came to their
ears.

"Sounds more like big guns."

"Oh, that's what it is!" agreed Alice. "They are going to rehearse one
of the battle scenes this afternoon, I heard Mr. Pertell say. The
soldiers must have come, and they're practising over in the glen. Come
on over and watch. We're in on the scenes later, but we can watch now."

"All right," agreed Ruth. "Wait until I get my broad-brimmed hat, the
sun is hot up here."

Presently the two sisters, with Paul Ardite and some other members of
the company, were strolling over the fields toward the scene of the
distant firing. As they came in sight of several hundred men and horses,
they saw
