"Give her more gas, Steve," begged Perry. "We can't have a little old
'puffing pig' of a boat like that walking away from us. Look at those
idiots grin!"

"And watch them change their faces," laughed Steve as he drew the
throttle forward another two or three notches. Under the hatches the
engine uttered a new note and a quick jarring became felt. Joe's anxiety
increased to uneasiness.

"Say, Steve, do you think--is it all right--I mean--"

"She's only doing about seventeen," replied Steve calmly. "The throttle
isn't nearly open yet. But I guess that's enough," he added as he
glanced across the water. Perry, leaning across the gunwale, beckoned
insultingly.

"Come on!" he called. "What are you stopping there for?"

The _Follow Me_ replied to the taunt, but what the reply was they didn't
know on the _Adventurer_, for the latter was ahead now by its full
length and gaining perceptibly every moment. Tom Corwin's head appeared
over the cabin roof, he took a look at the rival craft and popped from

abreast the _Adventurer's_ stern. Phil, who had been writing a letter in
the cabin, emerged and joined the group outside.

"How fast is she going, Steve?" he asked.
