What does Santiago have in his shack?

From the text:

The shack was made of the tough budshields of the royal palm which are called guano and in it there was a bed, a table, one chair, and a place on the dirt floor to cook with charcoal. On the brown walls of the flattened, overlapping leaves of the sturdy fibered [15] guano there was a picture in color of the Sacred Heart of Jesus and another of the Virgin of Cobre. These were relics of his wife.
