THE STORY OF ARTIFICIAL SILK 
was in the end overwhelmed by the obstacles 
that he encountered. In 1845 he died by his 
own hand. Apparently, his life had been a 
failure. In reality, he had succeeded. He 
was the first filament-maker in the world. He 
started a new process which has now become 
world-wide. 
Unhappily for Schwabe, he did not know 
what was being done at that time by a 
German—F. G. Keller, of Hainichen. Keller 
was a clever and inventive man. One day, 
he noticed some little children at play. 
They were making chains of cherry stones. 
They put the cherry stones in small hollows 
in a board and ground holes in them with a 
erindstone. 
Keller noticed that the grindstone ground 
a powder of wood, which fell in a pan of 
water. - He picked up some of this powder 
and noticed that it had been wetted into a 
pulp. He understood paper-making. All 
paper was at that time made of rags. It was 
scarce and dear. He thought: “ Why not 
make paper from wood ? ”’ 
He at once made experiments. He suc- 
ceeded. He made paper from wood pulp. He 
made no fortune out of his discovery. Others
