THE IDEAL _"This," said the Franciscan, "is my Automaton, who at the proper time will speak, answer whatsoever question I may ask, and reveal all secret knowledge to me." He smiled as he laid his hand affectionately on the iron skull that topped the pedestal._ _The youth gazed open-mouthed, first at the head and then at the Friar. "But it's iron!" he whispered. "The head is iron, good father."_ _"Iron without, skill within, my son," said Roger Bacon. "It will speak, at the proper time and in its own manner, for so have I made it. A clever man can twist the devil's arts to God's ends, thereby cheating the fiend--Sst! There sounds vespers!_ Plena gratia, ave Virgo--" _But it did not speak.

This story, overlaid as it is with mediaeval myth and legend, proves that Roger Bacon himself attempted the experiment--and failed." He shook a long finger at me. "Yet do not get the impression, Dixon, that Friar Bacon was not a great man. He was--extremely great, in fact; he lighted the torch that his namesake Francis Bacon took up four centuries later, and that now van Manderpootz rekindles." I stared in silence. "Indeed," resumed the Professor, "Roger Bacon might almost be called a thirteenth century van Manderpootz, or van Manderpootz a twenty-first century Roger Bacon.
