In this way my preparation for college went on without interruption. I found it much easier and pleasanter to be taught by myself than to receive instruction in class. There was no hurry, no confusion. My tutor had plenty of time to explain what I did not understand, so I got on faster and did better work than I ever did in school. I still found more difficulty in mastering problems in mathematics than I did in any other of my studies. I wish algebra and geometry had been half as easy as the languages and literature. But even mathematics Mr. Keith made interesting; he succeeded in whittling problems small enough to get through my brain. He kept my mind alert and eager, and trained it to reason clearly, and to seek conclusions calmly and logically, instead of jumping wildly into space and arriving nowhere. He was always gentle and forbearing, no matter how dull I might be, and believe me, my stupidity would often have exhausted the patience of Job. On the 29th and 30th of June, 1899, I took my final examinations for Radcliffe College. The first day I had Elementary Greek and Advanced Latin, and the second day Geometry, Algebra and Advanced Greek. The college authorities did not allow Miss Sullivan to read the examination papers to me; so Mr. Eugene C. Vining, one of the instructors at the Perkins Institution for the Blind, was employed to copy the papers for me in American braille. Mr. Vining was a stranger to me, and could not communicate with me, except by writing braille. The proctor was also a stranger, and did not attempt to communicate with me in any way. The braille worked well enough in the languages, but when it came to geometry and algebra, difficulties arose. I was sorely perplexed, and felt discouraged wasting much precious time, especially in algebra. It is true that I was familiar with all literary braille in common use in this country--English, American, and New York Point; but the various signs and symbols in geometry and algebra in the three systems are very different, and I had used only the English braille in my algebra. Two days before the examinations, Mr. Vining sent me a braille copy of one of the old Harvard papers in algebra. To my dismay I found that it was in the American notation. I sat down immediately and wrote to Mr. Vining, asking him to explain the signs. I received another paper and a table of signs by return mail, and I set to work to learn the notation. But on the night before the algebra examination, while I was struggling over some very complicated examples, I could not tell the combinations of bracket, brace and radical. Both Mr. Keith and I were distressed and full of forebodings for the morrow; but we went over to the college a little before the examination began, and had Mr. Vining explain more fully the American symbols.
