He led the children to a little pond, in which they could dimly see, by the light of the torch, fish sporting about in the water.
"Those fishes are happy as can be, yet they are perfectly blind. I made some experiments years ago that led me to discover it. You see how dark it is. The creatures living here would have no use for eyesight, so they gradually became blind. We can only keep the organs of our body in good condition by using them."
It was no wonder the children enjoyed the day with their father, as he always had so much of interest to tell them. This evening, as they sat on the balcony, Maria was talking about the fish that lived in darkness, when Ramon suddenly exclaimed:
"Look! look! the garden is fairly alive with lights. The cucujos are giving us a display of fireworks. Let's catch them, and have some fun. Except in the rainy season, it is not often that we see so many." He ran into the house for a candle, and the three children were soon chasing the cucujos along the walks.
The light of the candle attracted the insects, then it was an easy matter to catch hundreds of them in a fine thread net. We should call them fireflies, but they are much larger and more brilliant than any insect we have ever seen.
As they floated along above the flowers, Maria said they always made her think of fairies with their torch-bearers. The light was soft and cloud-like, yet it was bright enough to show the colours of the flowers, although the night was quite dark.
"Why not make a belt of them for your waists, as well as necklaces and bracelets?" Ramon asked his sisters. "Then you can go in and show yourselves to mother. You can tell her you are all ready for a party."
"All right," answered the girls. "But you must help us, Ramon."
How could the children do such things without hurting the beautiful little creatures, we wonder. But they knew a way, as they had done them before.
Each cucujo has a tiny hook near its head, which can be fastened in a person's clothing without harming it in the least. Grown-up ladies in Havana often adorn themselves in this way when going to a party. They look very brilliant, I assure you.
It was not many minutes before Maria and Isabella were fairly ablaze with lights. Then they danced into the house to be admired by their parents.
