“That will be the Tor of Glastonbury, I suppose,” said Smith, suddenly peering through his field-glasses in an easterly direction; “and yonder, unless I am greatly mistaken, is Cragmire Tower.”

Shading my eyes with my hand, I also looked ahead, and saw the place for which we were bound; one of those round towers, more common in Ireland, which some authorities have declared to be of Phoenician origin.  Ramshackle buildings clustered untidily about its base, and to it a sort of tongue of that oddly venomous green which patched the lowlands, shot out and seemed almost to reach the towerbase.  The land for miles around was as flat as the palm of my hand, saving certain hummocks, lesser tors, and irregular piles of boulders which dotted its expanse.  Hills and uplands there were in the hazy distance, forming a sort of mighty inland bay which I doubted not in some past age had been covered by the sea.  Even in the brilliant sunlight the place had something of a mournful aspect, looking like a great dried-up pool into which the children of giants had carelessly cast stones.

We met no living soul upon the moor.  With Cragmire Tower but a quarter of a mile off, Smith paused again, and raising his powerful glasses swept the visible landscape.

“Not a sign.  Petrie,” he said, softly; “yet . . .”

Dropping the glasses back into their case, my companion began to tug at his left ear.

“Have we been over-confident?” he said, narrowing his eyes in speculative fashion.  “No less than three times I have had the idea that something, or some one, has just dropped out of sight, behind me, as I focused . . .”

“What do you mean, Smith?”

“Are we”—­he glanced about him as though the vastness were peopled with listening Chinamen—­“followed?”

Silently we looked into one another’s eyes, each seeking for the dread which neither had named.  Then: 

“Come on Petrie!” said Smith, grasping my arm; and at quick march we were off again.

Cragmire Tower stood upon a very slight eminence, and what had looked like a green tongue, from the moorland slopes above, was in fact a creek, flanked by lush land, which here found its way to the sea.  The house which we were come to visit consisted in a low, two-story building, joining the ancient tower on the east with two smaller outbuildings.  There was a miniature kitchen-garden, and a few stunted fruit trees in the northwest corner; the whole being surrounded by a gray stone wall.

The shadow of the tower fell sharply across the path, which ran up almost alongside of it.  We were both extremely warm by reason of our long and rapid walk on that hot day, and this shade should have been grateful to us.  In short, I find it difficult to account for the unwelcome chill which I experienced at the moment that I found myself at the foot of the time-worn monument.  I know that we both pulled up sharply and looked at one another as though acted upon by some mutual disturbance.
