4. CHAPTER IV : THE SECRET TOWER (continued)

I glanced below. A hundred feet beneath lay jagged granite boulders at the brink of a frightful chasm upon which the tower abutted; and if not upon the boulders, then at the chasm's bottom, lay death, should a foot slip but once, or clutching fingers loose their hold for the fraction of an instant.

But there was no other way and with a shrug, which I must admit was half shudder, I stepped to the window's outer sill and began my perilous ascent.

To my dismay I found that, unlike the ornamentation upon most Heliumetic structures, the edges of the carvings were quite generally rounded, so that at best my every hold was most precarious.

Fifty feet above me commenced a series of projecting cylindrical stones some six inches in diameter. These apparently circled the tower at six-foot intervals, in bands six feet apart; and as each stone cylinder protruded some four or five inches beyond the surface of the other ornamentation, they presented a comparatively easy mode of ascent could I but reach them.

Laboriously I climbed toward them by way of some windows which lay below them, for I hoped that I might find ingress to the tower through one of these, and thence an easier avenue along which to prosecute my search.

At times so slight was my hold upon the rounded surfaces of the carving's edges that a sneeze, a cough, or even a slight gust of wind would have dislodged me and sent me hurtling to the depths below.

But finally I reached a point where my fingers could just clutch the sill of the lowest window, and I was on the point of breathing a sigh of relief when the sound of voices came to me from above through the open window.

"He can never solve the secret of that lock." The voice was Matai Shang's. "Let us proceed to the hangar above that we may be far to the south before he finds another way--should that be possible."

"All things seem possible to that vile calot," replied another voice, which I recognized as Thurid's.
