They were well-trained footmen, too; for at sight of me descending the stairs in my idiotic outfit they betrayed no surprise at all. One of them set his tray down on a table, stepped neatly ahead as Mr Felix reached the lowest stair, and opened a door for us on the right. I found myself at a stand on the threshold, blinking at a blaze of light, and staring up a perspective of waxed floor at a miniature stage which filled the far end of the room. Light, as every one knows, travels farther than sound: were it not so, I should say that almost ahead of the blaze there broke on us a din of voices--of happy children's voices. Certainly it stunned my ears before I had time to blink. The room was lined with children--scores of children: and some of them were gathered in little groups, and some of them, panting and laughing from their dance, had dropped into the chairs ranged along the walls. But these were the minority. The most of the guests lay in cots, or sat with crutches beside them, or with hands dropped in their laps. These last were the blind ones. I do not set up to be a lover of children: but the discovery that the most of these small guests were crippled hit me with a kind of pitiful awe; and right on top of it came a second and worse shock, to note how many of them were blind. To me these blind eyes were the only merciful ones, as Mr Felix beckoned Father Christmas to follow him up to the stage between the two lines of curious gazers. 'O--oh!' had been their first cry as they caught sight of me in the doorway: and 'O--oh!' I heard them murmuring, child after child, in long-drawn fugue, as we made our way up the long length of the room that winked detection from every candle, every reflector, every foot of its polished floor.
