I must have walked the streets till after midnight. At last I became so exhausted that I could walk no longer. I was tired; I was hungry; I was everything but discouraged. Just about the time when I reached extreme physical exhaustion, I came upon a portion of a street where the board sidewalk was considerably elevated. I waited for a few minutes, till I was sure that no passers-by could see me, and then crept under the sidewalk and lay for the night upon the ground, with my bag of clothing for a pillow. Nearly all night I could hear the tramp of feet over my head. The next morning I found myself somewhat refreshed, but I was extremely hungry, because it had been a long time since I had had sufficient food. As soon as it became light enough for me to see my surroundings I noticed that I was near a large ship, and that this ship seemed to be unloading a cargo of pig iron. I went at once to the vessel and asked the captain to permit me to help unload the vessel in order to get money for food. The captain, a white man, who seemed to be kind-hearted, consented. I worked long enough to earn money for my breakfast, and it seems to me, as I remember it now, to have been about the best breakfast that I have ever eaten.
