The Silk-Worm (.Bombyx mori ) was brought by monks to Constantinople 
about the middle of the sixth century. Before that time silk was imported in 
small quantities and at great cost from China, where the silk worm had been 
domesticated as 
early as 2700 B. 
C. For a long 
period the Greeks 
were the special 
European cultiva¬ 
tors of the silk¬ 
worm, until Italy 
wrested away its 
sceptre. From 
Italy, silk culture 
spread to Spain 
and France; in 
the latter country 
the production of 
the eggs is a large 
and well-recog¬ 
nized industry. 
The English have 
found their Indian 
possessions the 
most satisfactory 
place for their silk manufacture, and the Americans, while far behind their foreign 
competitors, yet have attained a reasonable success. 
Beginning with the egg, which at first is yellow, and later blue, the 
worm, when hatched, is black. At the end of eleven or twelve days the worm 
sheds its skin, or rather peels itself, and appears as a white caterpillar.
