"Why, this is 'adobe,' and it keeps out the sun's hot rays nicely. Don't you know what adobe is? It is a mixture of clay and sand dried by the sun. Some people call it unburnt brick. It was nearly white when the house was new, but now you see it is quite yellow."
There was no glass in the window-cases. In such a warm land as Cuba glass would keep out the air too much, and the people inside would suffer from the heat. But there were iron bars across the casements; there were also shutters to protect the house from the sun and rain.
The children went in at the door, opened by a black servant. She looked kind and pleasant, and showed two rows of white teeth as she smiled at the young visitors. A gorgeous yellow bandanna was wound around her head.
"Come right in, little dears. Massa and missus will be glad to see you; little Miss Lucia has been wishing for company to-day."
She led Ramon and Maria into a large sitting-room with two rows of rocking-chairs opposite each other. They stretched nearly from one end of the room to the other. There was scarcely any other furniture.
A minute afterward, Lucia opened the door. She was about Maria's age and very pretty. But she was dressed like a grown-up young lady. She carried in her hand a dainty little fan, which she moved gracefully as she talked.
"Oh, I am so glad to see you," she cried. "But let us go out into the garden; it is much pleasanter there; don't you think so? I want to show you my sensitive plant. Did you ever have one?"
Maria and Ramon had heard their father speak of this plant, but they had never happened to see one themselves. They followed Lucia out on the balcony. A morning-glory vine was trailing up the trelliswork. It was bright with its delicate blossoms, pink and blue and purple. Close beside it was the sensitive plant.
"It came up of itself," said Lucia. "That is, you know, it was not planted by any one. You see its leaves are wide open now. It is keeping the morning-glory blossoms company. Perhaps they are talking together. Who knows? But when night comes it will close up in the same way as the petals of its next-door neighbour."
"Now, Ramon, just touch the leaves gently."
