8. The Roman empire had been supplied with silk through the medium of the Persians, until the time of Justinian, in the year 555. This emperor, having become indignant at the rapacity of the silk-merchants, determined, if possible, to supply his people from the insect itself.
9. After many unsuccessful attempts, he at length obtained a small quantity of the eggs from India, by the assistance of two Persian monks, who had contrived to conceal them in the hollow of their canes. The seeds of the mulberry-tree, on the leaves of which the worm feeds, were also procured at the same time, together with instructions necessary for the management of the worms.
10. For six hundred years after the period just mentioned, the rearing of these worms, in Europe, was confined to the Greek empire; but, in the twelfth century, Roger, king of Sicily, introduced it into that island, whence it gradually spread into Italy, Spain, France, and other European countries.
11. The silk-worm was introduced into England by James the First; but it has never succeeded well in that country, on account of the dampness and coldness of the climate. The manufacture of fabrics from silk, however, is there very extensive, the raw material being obtained, chiefly, from Bengal and Italy. In the latter of these countries, in France, and other parts of Europe, as well as in Asia, the manufacture is also extensive.
12. Some attention has been paid to the rearing of silk-worms in the United States, and attempts have been made to introduce the manufacture of silks. The mulberry has been planted in various parts of the Union; and it is highly probable, that, in a few years, we shall be able to obtain excellent silks, without sending for them to foreign countries.
