Went this morning to hear Mr. Frothingham preach. His sermon was a most interesting one aiming to prove that the morality of its doctrine was an ideal one and not a practical one. Recommending an entire trust in Providence in all things whereas all experience proves that a trust in ones self only produces the best results. Humanity in the ages may come up to its level but it has not yet reached it. The whole discourse was profoundly interesting but he marred the effect of it by speaking too long a time, nearly two hours. Took a ride on the Elevated railway to the Park and down to the Battery & back and found it very pleasant. Wrote to Alice Sawyer and called on the Grays in the evening. Mrs. Gray told me Gray was very depressed and morbid. He came in after a while and seemed very glad to see me. Took a discouraging view of the Centennial and when I told him all that had been done he was quite surprised and felt more like cooperating. Wrote to Gertrude.
