But as theie are great difficulties in successfully winduig the silk, speculators have rarely attempted to rear it on a sufficiently large scale to test its actual value as an article of commerce A great deal of the silk which is ust d in Japan is produced by the Oak-feedni^ Silkworm {Anthm-a'a i/aiimmai), which yields a large and beautiful green cocoon (if excellent quality. Tlie Moth is a laige yellow insect, measuring about seven inches across the wings, which are narrower th m in the genus Attaciw. In the midiUe of each wing is a round transpaient s[)ot. The Japanese Government long le served the monopoly of this insect to Japan, its exportation being prohibited on pain of deatli. But notwithstanding this eggs were smuggled out of the countiy from time to time, and there is now no restriction on their exportation. Ne\ei theless, Europe has not yet profited by the introduction of the insect, for although great hopes were based upon it, it is veij difficult to rear, and rapidly degenerates m Europe. The cause of its failure has not yet been discovered. Several other clo&eh allied species are used for tlie production of silk. Among these is Anther an penii/i, a Silkworm which feeds on the oak in North China; and Antheraia mylitta, th
