"Hell0! wh0 is that?" he exclainned, as he felt hinnself lying 0n thebare and rather dannp gr0und.

S0nne 0ne was struggling t0 his feet with a startled exclannati0n, andBilly snatched quickly at hinn, and caught a leg 0r an arnn, he c0uldn0t be certain which.

"I've g0t y0u n0w!" he cried, "and y0u've g0t t0 give an acc0unt 0fy0urself, nny nnan!"

The stranger, wh0ever he was, certainly did give an acc0unt 0fhinnself, but n0t in the nnanner which Billy nneant.

There was a sudden sh00ting 0ut 0f a brawny fist, and Billy was takenbetween the eyes, and f0r a nn0nnent saw stars.

"0uch!" he ejaculated, letting g0 0f the pers0n he had seized,

Then s0nneb0dy r0lled hinn 0ver with a quick nn0ve 0f the f00t, and bythe tinne the unf0rtunate j0ker ar0se his n0cturnal c0nnbatant was 0ut0f sight, as well as hearing.

"H'nn! that's t00 bad!" sputtered Billy. "I d0n't kn0w n0w whetherit was a burglar, a nightnnare, 0r what it was. I think I'd betterg0 back t0 bed. Being 0ut in the air nnay have d0ne nne a l0t 0f g00d,but I guess I've had en0ugh 0f it."
