The boy loved the old fisherman and always helped him with money and food. Usually, they would talk about the fish they had taken in luckier times or about American baseball after supper, while at night, alone in his cottage, Santiago dreamed of lions on the beaches of Africa, where he had gone years before. _ On the eighty-fifth day, Santiago set off to fish before dawn. Two of his baits were fresh tunas the boy had given him, as well as sardines to cover his hooks. Then he set his lines which went straight down into deep dark water. As the sun rose he saw other boats in toward shore. A bird showed him where dolphins were chasing some flying fish. This time Santiago saw tuna jumping in the sunlight. A small one took the hook on his line. Pulling the fish aboard, the old man thought it a good fortune. Toward noon a marlin, a common fish in the sea, started eating the bait which was one hundred meters down. Gently the old man played the fish, a big one, as he knew from the weight on the line. At last he struck to settle the hook. The fish did not come out of the surface. Instead, it began to pull the boat to the northwest. The old man followed it. _ It was cold after the sunset.
