ON THE 
PRODUCTION OF SILKWORM GRAIN. 
By Mons. A. Roland. 
(From the Journal of the Society of Arts, April 25, 1873. J 
An unexpected opportunity has induced the writer of 
this paper to bring before public notice the following 
information, which he had intended to publish in the 
course of a few years. 
Having occupied myself for ten years past with the 
education, in the open air, of silkworm "grain," — 
having made, and still making every year, numerous 
experiments, I had thought, previous to writing this 
paper, of distributing, in countries fit for sericulture, 
several thousand ounces of good grain ; thus enabling 
myself, at the time of publication, to bring forward a 
convincing proof of the excellence of the system which 
it explains, by adding thereto a great number of 
certificates from silk reelers and educators. 
I do unquestionably possess a certain number of 
these certificates ; but having, within a few years only, 
given a greater degree of extension to my magnanerie, 
I should have wished the number of ounces of grain, 
acknowledged to be good, by the result of education, 
to be more considerable, and consequently better 
known.
