I'm Homer, the blind brother, I didn't lose my sight all at once, it was like the movies, a slow fade-out. When I was told what was happening I was interested to measure it, I was in my late teens then, keen on everything. What I did this particular winter was to stand back from the lake in Central Park where they did all their ice skating and see what I could see and couldn't see as a day-by-day thing. The houses over to Central Park West went first, they got darker as if dissolving into the dark sky until I couldn't make them out, and then the trees began to lose their shape, and then finally, this was toward the end of the season, maybe it was late February of that very cold winter, and all I could see were these phantom shapes of the ice skaters floating past me on a field of ice, and then the white ice, that last light, went gray and then altogether black, and then all my sight was gone though I could hear clearly the scoot scut of the blades on the ice, a very satisfying sound, a soft sound though full of intention, a deeper tone than you'd expect made by the skate blades, perhaps for having sounded the resonant basso of the water under the ice, scoot scut, scoot scut. I would hear someone going someplace fast, and then the twirl into that long scurratch as the skater spun to a stop, and then I laughed too for the joy of that ability of the skater to come to a dead stop all at once, going along scoot scut and then scurratch.

Of course I was sad too, but it was lucky this happened to me when I was so young with no idea of being disabled, moving on in my mind to my other capacities like my exceptional hearing, which I trained to a degree of alertness that was almost visual. Langley said I had ears like a bat and he tested that proposition, as he liked to subject everything to review. I was of course familiar with our house, all four storeys of it, and could navigate every room and up and down the stairs without hesitation, knowing where everything was by memory. I knew the drawing room, our father's study, our mother's sitting room, the dining room with its eighteen chairs and the walnut long table, the butler's pantry and the kitchens, the parlor, the bedrooms, I remembered how many of the carpeted steps there were between the floors, I didn't even have to hold on to the railing, you could watch me and if you didn't know me you wouldn't know my eyes were dead. But Langley said the true test of my hearing capacity would come when no memory was involved, so he shifted things around a bit, taking me into the music room, where he had earlier rolled the grand piano around to a different corner and had put the Japanese folding screen with the herons in water in the middle of the room, and for good measure twirled me around in the doorway till my entire sense of direction was obliterated, and I had to laugh because don't you know I walked right around that folding screen and sat down at the piano exactly as if I knew where he had put it, as I did, I could hear surfaces, and I said to Langley, A blind bat whistles, that's the way he does it, but I didn't have to whistle, did I? He was truly amazed, Langley is the older of us by two years, and I have always liked to impress him in whatever way I could. At this time he was already a college student in his first year at Columbia. How do you do it? he said. This is of scientific interest. I said: I feel shapes as they push the air away, or I feel heat from things, you can turn me around till I'm dizzy, but I can still tell where the air is filled in with something solid.

And there were other compensations as well. I had tutors for my education and then, of course, I was comfortably enrolled in the West End...
