New York, October 9, '62 General, "There is a time for every- thing" as Solomon had it; suppose then you cast off for this evening the General, the Ambassador, the Politician and the Refor- mer, and based upon the Motto "that he who tries to make others happy has a right to be happy himself", Kindly accompany me to the Opera House, where the opera "Czaar and Carpenter" is to be performed this evening. The music is one of the best German operas and the text "Peter the Great and his forturnes" may be of some special interest to our Russian Ambassador. I shall give myself the honor of calling on you at 7 this P.M. and shall be most happy to find you ready to accept my invi- tation. Until then , Your most obedient servant M. Pinner
