Then a trip to Ellis Island, and at midnight that same date he wrote:  “Just had a most truly remarkable—­eight-thirty to twelve—­visit with Professor Robinson, he who wrote that European history we bought in Germany.”  Then a trip to Philadelphia, being dined and entertained by various members of the Wharton School faculty.  Then the Yale-Harvard game, followed by three days and two nights in the psychopathic ward at Sing Sing.  “I found in the psychiatrist at the prison a true wonder—­Dr. Glueck.  He has a viewpoint on instincts which differs from any one that I have met.”  The next day, back in New York:  “Just had a most remarkable visit with Thomas Mott Osborne.”  Later in the same day:  “Just had an absolutely grand visit and lunch with Walter Lippmann . . . it was about the best talk with regard to my book that I have had in the East.  He is an intellectual wonder and a big, good-looking, friendly boy.  I’m for him a million.”

Then his visit with John Dewey.  “I put up to him my regular questions—­the main one being the importance of the conflict between MacDougall and the Freudians. . . .  He was cordiality itself.  I am expecting red-letter days with him.  My knowledge of the subject is increasing fast.”  Then a visit with Irving Fisher at New Haven.  The next night “was simply remarkable.”  Irving Fisher took him to a banquet in New York, in honor of some French dignitaries, with President Wilson present—­“at seven dollars a plate!” As to President Wilson, “He was simply great—­almost the greatest, in fact is the greatest, speaker I have ever heard.”

Then a run down to Cambridge, every day crammed to the edges.  “Had breakfast with Felix Frankfurter.  He has the grand spirit and does so finely appreciate what my subject means.  He walked me down to see a friend of his, Laski, intellectually a sort of marvel—­knows psychology and philosophy cold—­grand talk.  Then I called on Professor Gay and he dated me for a dinner to-morrow night.  Luncheon given to me by Professor Taussig—­that was fine. . . .  Then I flew to see E.B.  Holt for an hour [his second visit there].  Had a grand visit, and then at six was taken with Gay to dinner with the visiting Deans at the Boston Harvard Club.”  (Mr. Holt wrote:  “I met Mr. Parker briefly in the winter of 1916-17, briefly, but so very delightfully!  I felt that he was an ally and a brilliant one.”)

I give these many details because you must appreciate what this new wonder-world meant to a man who was considered nobody much by his own University.

Then one day a mere card:  “This is honestly a day in which no two minutes of free time exist—­so superbly grand has it gone and so fruitful for the book—­the best of all yet.  One of the biggest men in the United States (Cannon of Harvard) asked me to arrange my thesis to be analyzed by a group of experts in the field.”  Next day he wrote:  “Up at six-forty-five, and at seven-thirty I was at Professor Cannon’s.
