SILKWORM GRAIN.

expense, that is, in the shortest space of time, the most 
abundant supply of cocoons. Anyone may, therefore, 
easily understand the immense difference which exists 
between the two kinds of education. 
Artificial heat is required in the magnanerie which 
is to produce silk, for fear of the education being pro- 
tracted too long, and the profits of the undertaking 
being absorbed in the attendant expenses. 
Any one living in the country may, with good grain, 
easily obtain a profitable supply of cocoons ; but, 
although the system is very simple, and, with the help 
of two manchons, any peasant may produce the grain 
lie requires, still no chance speculator will ever make 
good grain in any considerable quantity, for the reason, 
simple enough no doubt, but, nevertheless, very true, 
that he rarely pursues art for its own sake ; and the 
mercantile element will always prevail with the 
multitude over the scientific and the reasonable. 
I therefore consider it a matter of great importance 
for the future advancement of sericulture that a con- 
siderable number of persons should devote their atten- 
tion to this open-air education for grain. They will 
find in it both profit and satisfaction ; profit — because 
the protracted and numerous cares which it requires 
are amply remunerated by the sale of good grain, 
always in great demand ; satisfaction from the scientific 
and philanthropic side of the question ; for, by furnish- 
ing the silk-producing population with the means of 
obtaining good supplies of our former beautiful 
indigenous races, great sufferings will be relieved. 
I consider it my duty to append to this paper the 
honourable certificate, which I received from Monsieur 
A. Gaydou, of the house of Gaydou and Co., Turin.
