The sloping green of the campus below Bentley Hall was inviting. Between classes I made my way one day to a seat under a tree only to hear a horrified call from the walk above, “Come back, come back quick.” An imperative summons from an upper-class woman. “You mustn’t go on that side of the walk, only men go there.” It was not so simple to find a spot where you could go and be comfortable. If Bentley Hall, where all the classes were held, was a beautiful piece of architecture, its interior could hardly have been more severe. The rooms were heated with potbellied cast-iron stoves, seated with the hardest wooden chairs, lighted by kerosene lamps. In winter (and the winters were long) the snow tracked in kept the floors wet and cold. Often one wore a muffler in chapel. But of all that I was unheeding. My pioneer childhood served me well. Moreover, I realized at the start that I had found what I had come to college for, direction in the only field in which I was interested—science. I found it in a way that I doubt if Cornell could have given me at the moment, shy and immature as I was: the warming and contagious enthusiasm of a great natural teacher, one who had an ardent passion for those things which had stirred me and a wide knowledge which he fed by constant study and travel—Jeremiah Tingley, the head of Allegheny’s department of natural science. Professor Tingley was then a man of fifty, sparkling, alive, informal. Three years before, he had been one of the fifty chosen from many hundred applicants to spend the summer with Louis Agassiz on the island of Penikese in Buzzards Bay. Agassiz had planned with enthusiasm for the Penikese Summer School, and for those privileged to enter who could understand and appreciate it was an unforgettable experience; certainly it was for Jeremiah Tingley. He carried there Agassiz’s faith in observation and classification, as well as his reverence for Nature and all her ways. For both men the material world was but the cover of the spirit. Professor Tingley would quote Agassiz sometimes: “Nature always brings us back to absolute truth whenever we wander.” This fervent faith had a profound and quieting effect on my religious tumult. I learned a new word: Pantheism. Being still in that early stage of development where there must be a definite word by which to classify oneself, I began to call myself a pantheist—and I had a creed which I repeated more often than the creed I had learned in childhood: Flower in the crannied wall, I pluck you out of the crannies, I hold you here, root and all, in my hand Little flower—but _if_ I could understand What you are, root and all, and all in all, I should know what God and man is. It reassured me; I was on the right track, for was I not going to find out with the microscope what God and man are?
