ing to took a chance. I go, und das Lena goes,
und by und by maybe we make blenty money und go ashore to shtay."

"You take it easy, I must say!" returned Jimmie, somewhat amused.

"Are you going out just the same, Captain?" inquired Jack.

"Sure!" proclaimed the captain, in no uncertain tones.

"Then let's be getting that truck and take the Grey Eagle boxes aboard
the Lena Knobloch!" cried Jack. "The sooner it's over the easier I'll
feel. I'm beginning to get nervous about all this 'U-13' business!"

After paying their bill the boys set out in company with the captain to
find the trucker. That individual put up a strong protest at taking out
his horses at the unseemly hour, but a piece of coin slipped into his
hand at the opportune moment by Ned soon changed his mind.

Another piece of money changing hands at the proper moment secured the

CHAPTER V

TWO MYSTERIOUS CHANGES

"Hey, you!" shouted Jimmie, dashing across the street in the direction of
the queer outfit. "Come here! I want to see you!"

The pseudo milk vendor gave a quick glance at the approaching boy. A
street lamp cast a flickering glare upon the automatic which Jimmie had
drawn from his pocket. Without waiting to explain or ask questions the
person addressed deserted the dog team instantly.

With but a single look over its shoulder the figure darted toward a
building at the head of the quay. Boots clattered on the pavement, while
the long stride clearly indicated to the boys that Jimmie and Jack had
been correct in their surmise that the g
