The landlady watched the experiments for some time in silence. Then, with a little laugh, she said, 'Ah, M. Montgolfier, why do you not tie the fire to the bag?'
The great inventor had not thought of that; but he did not require to be told twice, and obtaining a little bunch of some inflammable material, he tied it under his bag and set it on fire. The smoke and heat inflated the tiny balloon, and it rose at once to the ceiling. A few minutes later the inventor called for pen and ink, and wrote the following letter:
'Prepare without delay a supply of taffeta and cordage, and you shall see one of the most astonishing things in the world.'
This hasty note was addressed to M. Stephen Montgolfier at Annonay, near Lyons, and never was a request made that was more likely to be carefully and promptly granted. Stephen Montgolfier, like his brother, had busy thoughts concerning means for rising in the air, and when Joseph returned from Avignon, they set to work with stronger hope of realising their dreams. As they were the largest and best paper-makers in Annonay, they did not lack material for carrying on experiments, and when these experiments had repeatedly resulted in success, they decided that the rest of the world should be admitted into their secret. A large balloon, made of paper and taffeta, should be inflated in the public square, and be allowed to rise before the eyes of any who might gather there to see it. And they carried out this determination on June 5th, 1783. On that day there assembled at Annonay a number of local celebrities, and no better opportunity could have been chosen.
In the public square a large circular space was railed off to keep the crowd at a proper distance, and in the centre of this space rose a wooden platform to accommodate the new cloud-ship and the fire which was to fill it with the power of flight. Never had the brothers Montgolfier had a busier morning; never had the good people of Annonay seen such excitement in their quiet village. The crowd had gathered from far and near, and watched the busy workers round the mysterious platform with widely different thoughts. Some were silent with expectation, some jeered noisily; but, unconscious of praise or laughter, the two brothers directed their little band of workmen, confident of coming triumph.
