the stores are. We'll lose track of her if we don't."

"Do you suppose any one will notice that we're disguised?"

"I hope not. There's usually a big crowd on the streets Saturday
night though."

"We'll hope for luck," said Hugh earnestly.

They quickened their paces until they were scarcely more than
seventy-five feet in back of Lena. There were many people passing them in
both directions now, and apparently Lena was not as suspicious as she had
been; she glanced behind her no more.

Presently they turned into the main street. The sidewalks were thronged
with people and everything was lighted up brilliantly in the glare of
arclights and shop windows. Lena was just ahead of the boys and it was
not an easy task to follow her in the crowd.

Music sounded down the street. A troop of cavalry was approaching and
every one lined the curb to see them pass. Lena stopped and the boys
took their places directly behind her. Every trooper was mounted on a
coal black horse, and they made a fine showing as they drew near; the
crowd began to cheer and many waved small American flags that they were
carrying. Women waved their handkerchiefs as the horsemen passed, and
much to both Bob's and Hugh's surprise Lena waved her handkerchief and
clapped her hands with the others.

"What do you think of that?" whispered Bob.
