He thought for some moments. When he raised his face it was gray.

"One of the bottles was broken. I had reason to believe it the pilocarpin," he said quietly. "Can I trespass on your good nature to make the proper solution for my eyes?"

"It is but a temporary expedient," warned Winkleman. "It is surgery here demanded. I know the operation, but I cannot perform. One makes a transverse incision above the cornea----"

"I know, I know," interrupted Kingozi. "But the pilocarpin will give me my sight. Let us get at it."

LIGHT AGAIN

Three hours later Kingozi stepped into the open, his vision cleared. Such is often the marvellous--though temporary--effect of the proper remedies in this disease. He looked about him with a thankfulness not to be understood save by one whose sight has been thus unexpectedly restored. Winkleman followed him full of deep sympathy.

"But I understand," he repeated over and over, "but it is like water on a weary march, nicht wahr. But this is bad, very bad! You say it has been going on for a month? And a month back! Too late. Ach, schrecklich! It is so much a pity! You have, the youth, the strength, the knowledge! You could so far go! But you must learn the dictation; the great book, the magnum opus, it is there. Cheer up, my boy! Work, much work! That is what will cure your sick courage even if it cannot cure your sick eyes. Now, while we have the sight--see--the bone--this curve clearly indicates to me----"

Winkleman produced the saurian bone. And for the first time Kingozi noticed Simba hovering anxiously near. Request and blandishments had proved of no avail in getting the magic bone from Bwana Nyele.

"It is all right," Kingozi reassured him. "We but use the magic for a little while. See; it has given me back my eyes."
