"Oh, well, come on and skate!" invited Betty. "Amy and I will race you and Mollie, Grace. That will—make us all feel better," for the Little Captain, as she was often called, saw just the shadow of a cloud gathering over the two chums, who seldom, or never, quarreled.

"Does Amy want to?" asked Grace, glancing at a quiet girl who was adjusting her skates. Amy was always quiet, but of late her chums had noted that she was more than usually so. And they guessed, rightly, that it had to do with the mystery surrounding her identity, which mystery Amy had almost given up hope of solving.

"Yes, I'll race," said Amy gently, and she smiled. Amy was always willing to oblige, and she did not often consult her own personal feelings.

Something like a look of disappointment passed over the countenance of Grace. Seeing it Mollie laughed.

"Grace was hoping Amy would say no, so she could get out of it!" cried vivacious Mollie. "That's the time you didn't say the right thing, Amy."

"Oh, well, if nothing but a race will satisfy you, I suppose I must," and Grace gave in "gracefully." "I'm nearly perished standing still, anyhow, and skating can't make me much worse."

"It will be all the better," insisted Betty. "Now we'll race in this fashion—team work to count. Amy and I in one team, you and Grace in the other, Mollie. Whichever member of the team gets to the bend first will win. You see," Betty explained, "one of a team might fall, or turn her ankle, or get tired, and then the other could keep on. It's like a relay race."

"Oh, well, if I have to—I suppose I have to," and Grace said this with such a doleful sigh that the others laughed heartily, even quiet Amy joining.

"On your marks!" cried Betty. "Let's show that we are worthy of our names—true Outdoor Girls."

"Show who?" asked Grace looking around.
