"I can recall how proud I was when he sent me to beautiful music-loving Helsingfors, in Finland—where all seems to be bloodshed and confusion now—to play a recital in his own stead on one occasion, and how proud he was of my success. Yet Auer had his little peculiarities. I have read somewhere that the great fencing-masters of the sixteenth and seventeenth centuries were very jealous of the secrets of their famous feints and ripostes, and only confided them to favorite pupils who promised not to reveal them. Auer had his little secrets, too, with which he was loth to part. When I was to make my début in Berlin, I remember, he was naturally enough interested—since I was his pupil—in my scoring a triumph. And he decided to part with some of his treasured technical thrusts and parries. And when I was going over the Tschaikovsky D minor concerto (which I was to play), he would select a passage and say: 'Now I'll play this for you. If you catch it, well and good; if not it is your own fault!' I am happy to say that I did not fail to 'catch' his meaning on any occasion. Auer really has a wonderful intellect, and some secrets well worth knowing. That he is so great an artist himself on the instrument is the more remarkable, since physically he was not exceptionally favored. Often, when he saw me, he'd say with a sigh: 'Ah, if I only had your hand!'
