and in the convents. All classes have constantly impressed 
upon them through the public journals, its usefulness and 
importance. The raising of a few pounds of cocoons each 
year, need not materially interfere with other duties, and it 
is by each household raising a few pounds of cocoons that 
silk culture must, in the end, be carried on in this, as it has 
always been in other countries, Large rearing establish- 
ments seldom pay. 
There are 380 silk mills in the United States. Two-thirds 
of the raw silk which they use is imported, for which thirty- 
five million dollars are annually sent abroad. There is na 
reason why the entire demand of the mills should not be 
supplied by cocoons produced in this country. 
In compiling this manual, I am indebted for information 
and favors to M. de Boissiere, Senator Plumb, and others, 
and to Prof. C. V , Riley for permission to use his reports.
