He looked in amazement at the little fern, growing in the sealed jar. According to Dr Ward it had been growing there for three years.
“But what nourishes it?”
“Sunlight.” He replied, “Water evaporates, and condenses in the jar. Minerals feed the leaves, and return to the soil, all it needs is light.”
“Is it of any use?”
“Use! Glass boxes filled with plants, on a ships deck, will carry them safely around the world. We will move useful plants wherever we want. This could end famines, create industries and beautify gardens, it could change the world.”

In 1829 Dr Nathanial Ward tried to hatch out a moth chrysalis, it died, but a tiny fern seedling growing in the jar continued to grow although Dr Ward did nothing. Realising what this might mean he experimented and a decade later had a successful box for transporting pants around the world. Properly named the Wardian Case, after its inventor, it was used to transport medicinal, food and commercial crops around the globe. It really did change the world.
