“Oh!” said Helen May quite flatly, dropping her hands from her sunburned face and looking Starr over with the self-possessed, inquiring eyes of one who is accustomed to gazing upon strange faces by the thousands.

“How do you do?” said Starr, lifting his hat and foregoing instinctively the easy “Howdy” of the plains.  “Is—­Mr. Calvert at home?”

“That depends,” said Helen May, “on where he calls home.  He isn’t here, however.”

Rabbit, not in the least confused by the presence of a girl in this out-of-the-way place, pushed forward and thrust his nose deep into the lower pool of the spring where the water was warmed a little by the sun on the rocks.  Starr could not think of anything much to say, so he sat leaning forward with a hand on Rabbit’s mane, and watched the muscles working along the neck, when the horse swallowed.

“Oh—­would you mind killing that beast down there in that little hollow?” Helen May had decided that it would be silly to keep on shouting for Vic when this man was here.  “It’s what they call a young Gila Monster, I think.  And the bite is said to be fatal.  I don’t like the way he keeps looking at me.  I believe he’s getting ready to jump at me.”

Starr glanced quickly at her face, which was perfectly serious and even a trifle anxious, and then down in the direction indicated by a broken-nailed, pointing finger.  He did not smile, though he felt like it.  He looked again at Helen May.

“It’s a horned toad,” he informed her gravely.  “The one Johnny Calvert kept around for a pet, I reckon.  He won’t bite—­but I’ll kill it if you say so.”  He dismounted and picked up a stone, and then looked at her again inquiringly.

Helen May eyed the toad askance.  “Of course, if it’s accustomed to being a pet—­but it looks perfectly diabolical.  It—­came after me.”

“It thought you would feed it, maybe.”

“Well, I won’t.  It can think again,” said Helen May positively.  “You needn’t kill it, but if you’d chase it off somewhere out of sight—­it gives me shivers.  I don’t like the way it stares at a person and blinks.”

Starr went over and picked up the toad, holding it cupped between his palms.  He carried it a hundred feet away, set it down gently on the farther side of a rock, and came back.  “Lots of folks keep them for pets,” he said.  “They’re harmless, innocent things.”

He washed his hands in the pool where Rabbit had drunk, took the tin can that had stood on a ledge in the shade when Starr first came to the spring a year ago, and dipped it full from the inner pool that was always cool under the rocks.  He turned his back to Helen May and drank satisfyingly.  The can was rusted and it leaked a swift succession of drops that was almost a stream.  Helen May decided that she would bring a white granite cup to the spring and throw the can away.  It was unsanitary, and it leaked frightfully, and it was a disgrace to civilized thirst.
