"Oh, that no maller," replied Chow, with a sullen grin. "Him plenty 'shipmen come here and smoke." "You lie!" hissed Dave, grasping the heathen by the collar and shaking him until the latter's teeth rattled. Then Dave gave him a brief rest, though he still retained his hold on the Chinaman's collar. But the yellow man began struggling again, and Dave repeated the shaking. Chow Hop had kept his hands up inside his wide sleeves. Now Farley leaped forward as he shouted: "Look out, Darry! He has a knife!" Farley attempted to seize the Chinaman's wrist, for the purpose of disarming the yellow man, but Dave swiftly threw the Chinaman around out of Farley's reach. Then, with a lightning-like move, Dave knocked the knife from Chow Hop's hand. "Pick that up and keep it for a curio, Farley," directed Dave coolly. In another twinkling Darrin had run the Chinaman up against the wall. Smack! biff! thump! With increasing force Dave's hard fist struck the heathen in the face. "Now stand there and behave yourself," admonished Midshipman Dave, dropping his hold on the yellow man's collar, "or we'll stop playing with you and hurt you some." The scowl on Chow Hop's face was ominous, but he stood still, glaring at Dave. "Chow, what can we do to bring this man out of his sleep!" asked Dave coolly, and almost in a friendly tone. "Me no sabby," sulked the Chinaman. "Yes, you do," retorted Dave warningly. "Now, what can we do to get our friend out of this!" "You allee same cally (carry) him out," retorted Chow, with a suspicion of a sulky grin. "None of that, now, you yellow-face!" glared Dave. "How shall we get our comrade out of this opium sleep!" "Me no sabby no way," insisted Chow. "Oh, yes, you do!" snapped Dave. "But you won't tell. All right; we'll find the way, and we'll punish you into the bargain. Dan, get a piece of paper from the other room." Dalzell was quickly back with the desired item. On the paper Dave wrote a name and a telephone number. "It's near the end of the doctor's office hours," murmured Dave. "Go to a telephone and ask the doctor to meet you at the corner above. Tell him it's vastly important, and ask him to meet you on the jump." "Shall I tell him what's up!" asked Dan cautiously. "Yes; you'd better. Then he'll be sure to bring the necessary remedies with him." Dan Dalzell was off like a shot. Chow tried to edge around toward the door. "Here, you get back there," cried Dave, seizing the Chinaman and slamming him back against the wall. "Don't you move again, until we tell you that you may--or it will be the worse for you." Ten minutes passed ere Dan returned with Dr. Lawrence. "You see the job that's cut out for you," said Darrin, pointing to the unconscious figure in the bunk. "Can you do it, Doctor?" The medical man made a hasty examination of the unconscious midshipman before he answered briefly: "Yes." "Will it be a long job, Doctor?" "Fifteen minutes, probably."
