erops, the opening of trade directly with China and 

 Japan, the cheaper labor of France and Italy, — all these 

 factors have made the business precarious and unprofit- 

 able. "This branch of industry," writes the l>ot;mi>t- 

 fcraveler, Michaux, early in this century, "is adapted 

 only t<> a populous country, where there are hands not 

 required for the cultivation of the earth that may be 

 employed in manufactures so as to afford their products 

 at moderate prices. In the United States this period is 

 still remote." Yet the persistenl experiments to grow 

 silk have been productive of good results, aside from 

 teaching us what the limitations of our country are. 

 A very Large Bilk -manufacturing industry has arisen, 

 the fabrics being made from imported raw silks. The 

 Del annual valn<- of the finished goods of American 

 manufacture is about seventy million dollars, ami the 

 annual imports of raw silks reach aboul six million 

 pounds. 



Bui there is another curious developmenl of all

 of the mulberry itself, and this is the theme which 

 forms the proper subject and conclusion of all thivili —

followed the COUrSe of the development of the silk 



industry, but have neglected the Bubsequenl conn 

 the mulberry, npon which all the efforts at silk produc-

 the comparative unimportance of the mulberrj tor any
