discover the theory of the circulation of the blood; it is the business
of lesser men to apply the discovery to practical ends. It takes a
Whitney to invent the cotton gin, but the dullest negro roustabout can

can formulate the eternal laws of social evolution can safely leave it
to others to put his laws into practice."

Sharlee gazed at him in silence, and he returned her gaze, his face

"Yes.... Do I understand that you--derive your living from these social
laws that you write up for others to practice?"

"Oh, no--impossible! There is no living to be made there. When my book
comes out there may be a different story, but that is two years and ten
months off. Every minute taken from it for the making of money is, as
you may now understand, decidedly unfortunate. Still," he added
depressedly, "I must arrange to earn something, I suppose, since my
father's assistance is so problematical. I worked for money in New York,
for awhile."

"Oh--did you?"

"Yes, I helped a lady write a thesaurus."
