“Here, let me go.  You’re scaring off the only evidence we’ve got that Johnny landed here.  You stay right here and behave yourself, young lady.  I might want to ’phone you, if I get a clue—­”

“Oh, dad!  Cross your heart you’ll ’phone the very instant you find out anything?  Here’s your hat—­do, for gracious sake, hurry!”

CHAPTER TWENTY-ONE

JOHNNY IS NOT PAID TO THINK

On that same Saturday afternoon, at about the time when Mary V sighted Bland at the southeast corner of Sixth and Spring, Johnny stood just under the peak behind Mateo’s cabin and saw a lone horseman ride across the upper neck of the little valley and disappear into the brush on the side opposite him.  He waited impatiently.  The rider did not reappear, but presently he saw what looked like a human figure crouched behind a rock well up the slope.  Johnny stared until his eyes watered with the strain, but he could not be sure that the object was a man.  If it were, the man was without a doubt placed there for purposes of observation.  The thought was not a pleasant one.

He waited, himself crouched now behind a jutting fragment of rock, and thought he saw the object move.  A little later the sun, sliding farther down the sky, reflected a glittering something just above that rock.  A bit of glass would do that—­the lenses of a field glass, for instance.  Two lenses would shine as one, Johnny believed, and was thankful that his slope was in shadow.

Taking it for granted that some one was watching the valley, he studied the spot where the glitter had already winked out—­possibly because the man had moved the field glasses, sweeping the valley.  It was a good place for a spy, Johnny admitted.  There was a slight ridge just there, so that the view was clear for some distance in either direction; Mateo’s cabin was in plain sight, and the surrounding hills.  He hoped the fellow would see nothing suspicious and would presently give up that post; in the meantime he was effectually treed.  There was no shelter that he dared trust on the first rocky half of the descent, and to climb up and over the peak he would surely reveal himself, unless the fellow’s attention happened to be centered on something else.

Johnny studied his predicament.  The man could see everything—­but could he hear?  He was half a mile off, Johnny judged, estimating the distance with an accuracy born of long living in the country of far skylines.  The spy would need sharp ears indeed to hear anything less than a shout.

Johnny picked up a pebble, aimed, and threw it at the roof of Mateo’s cabin.  The pebble landed true and rattled off, hitting the ground with a bounce and rolling away in the grass.  The children, playing in the open as they always did, stopped and looked up inquiringly, then went on with their play.  Mateo came cautiously from the back door and to him Johnny called, thankful that the observer on the hillside could not see through the cabin to where Mateo stood.
