But a more special interest of his lay in prison reform.  The subject had engaged his attention long before he published anything in connection with it.  Later one of the earliest articles he wrote for Harper’s Magazine was devoted to it.  It was in his thoughts just before his death.  He was a member of the Connecticut commission on prisons, of the National Prison Association, and a vice-president of the New York Association for Prison Reform.  A strong advocate of the doctrine of the indeterminate sentence, he had little patience with many of the judicial outgivings on that subject.  To him they seemed opinions inherited, not formed, and in most cases were nothing more than the result of prejudice working upon ignorance.  This particular question was one which he purposed to make the subject of his address as president of the Social Science Association, at its annual meeting in 1901.  He never lived to complete what he had in mind.

During his later years the rigor of the Northern winter had been too severe for Warner’s health.  He had accordingly found it advisable to spend as much of this season as he could in warmer regions.  He visited at various times parts of the South, Mexico, and California.  He passed the winter of 1892-93 at Florence; but he found the air of the valley of the Arno no perceptible improvement upon that of the valley of the Connecticut.  In truth, neither disease nor death entertains a prejudice against any particular locality.  This fact he was to learn by personal experience.  In the spring of 1899, while at New Orleans, he was stricken by pneumonia which nearly brought him to the grave.  He recovered, but it is probable that the strength of his system was permanently impaired, and with it his power of resisting disease.  Still his condition was not such as to prevent him from going on with various projects he had been contemplating or from forming new ones.  The first distinct warning of the approaching end was the facial paralysis which suddenly attacked him in April, 1900, while on a visit to Norfolk, Va.  Yet even from that he seemed to be apparently on the full road to recovery during the following summer.

It was in the second week of October, 1900, that Warner paid me a visit of two or three days.  He was purposing to spend the winter in Southern California, coming back to the East in ample time to attend the annual meeting of the Social Science Association.  His thoughts were even then busy with the subject of the address which, as president, he was to deliver on that occasion.  It seemed to me that I had never seen him when his mind was more active or more vigorous.  I was not only struck by the clearness of his views—­some of which were distinctly novel, at least to me—­but by the felicity and effectiveness with which they were put.
