His surprise was very noticeable when he saw Miss Motuble. His lips quivered and tears began to flow from his eyes, like water from a fountain.

Julio Murillo shook hands with the three men, asked them to be seated, and then turned his attention to the little girl, who stood modestly by the door waiting to tell the object of her call.

“How many posies must I buy from my little flower girl this morning?” said Julio.

“One,” replied the child, “if it so pleases your honor, for it will please thy mother, Señora Suzzan Carriles, for you to do so.”

“Bless the dear one,” cried Marriet Motuble, “we will buy every posy she has. Come, gentlemen, now is the opportunity to show your gratitude to science through this child, who is the living proof of our friend’s investigations. Come, gentlemen, who will bid on this child’s posies? One dollar for each flower. One dollar once, one dollar twice——”

“Three dollars for each flower,” cried a voice from Guillermo Gonzales’ reception-room.

Julio Murillo greeted the bidder as he stepped into the little study, with great joy. He was accompanied by the scientist, Guillermo Gonzales, who was no stranger to the three men, they wasted no time to show their good will and great respect for him.

The flower-girl curtesied to the two distinguished men. She was something more than a simple child to them. She was the living proof of their scientific investigations.

The fair auctioneer continued crying: “Three dollars for each posy once; three dollars for each posy twice; three dollars for each posy——”

“Four dollars I bid!” cried the blear-eyed, spotted faced, bald-headed, dissipated looking man. “Four dollars, I say. Four dollars, I say.”
