“Guardy,” the voice of the elfin child rang silvery in the silence, as she pressed close to her companion.  “Guardy, is he preaching?”

“Yes, my dear little child.”  The orator saw his opportunity and swooped upon it, with a flash of dazzling teeth from under his pliant lips.  “This sweet little girl asks if I am preaching.  I thank her for the word.  Preaching, indeed!  Preaching a blessed gospel, for this world of pain and suffering; a gospel of hope and happiness and joy.  I offer you, here, now, this moment of blessed opportunity, the priceless boon of health.  It is within reach of the humblest and poorest as well as the millionaire.  The blessing falls on all like the gentle rain from heaven.”

His hands, outstretched, quivering as if to shed the promised balm, slowly descended below the level of the platform railing.  Behind the tricolored cheesecloth which screened him from the waist down something stirred.  The hands ascended again into the light.  In each was a bottle.  The speaker’s words came now sharp, decisive, compelling.

“Here it is!  Look at it, my friends.  The wonder of the scientific world, the never-failing panacea, the despair of the doctors.  All diseases yield to it.  It revivifies the blood, reconstructs the nerves, drives out the poisons which corrupt the human frame.  It banishes pain, sickness, weakness, and cheats death of his prey.  Oh, grave, where is thy victory?  Oh, death, where is thy power?  Overcome by my marvelous discovery!  Harmless as water!  Sweet on the tongue as honey!  Potent as a miracle!  By the grace of Heaven, which has bestowed this secret upon me, I have saved five thousand men, women, and children from sure doom, in the last three years, through my swift and infallible remedy, Professor Certain’s Vitalizing Mixture; as witness my undenied affidavit, sworn to before Almighty God and a notary public and published in every newspaper in the State.”

Wonder and hope exhaled in a sigh from the assemblage.  People began to stir, to shift from one foot to another, to glance about them nervously.  Professor Certain had them.  It needed but the first thrust of hand into pocket to set the avalanche of coin rolling toward the platform.  From near the speaker a voice piped thinly:—­

“Will it ease my cough?”

The orator bent over, and his voice was like a benign hand upon the brow of suffering.

“Ease it?  You’ll never know you had a cough after one bottle.”

“We-ell, gimme—­”

“Just a moment, my friend.”  The Professor was not yet ready.  “Put your dollar back.  There’s enough to go around.  Oh, Uncle Cal!  Step up here, please.”

An old negro, very pompous and upright, made his way to the steps and mounted.

“You all know old Uncle Cal Parks, my friends.  You’ve seen him hobbling and hunching around for years, all twisted up with rheumatics.  He came to me yesterday, begging for relief, and we began treatment with the Vitalizing Mixture right off.  Look at him now.  Show them what you can do, uncle.”
