PREFACE 



TO THE FRENCH EDITION. 



THE Minister of Public Works, of Agriculture and Commerce, 

 has invited M. CAMILLE BEAUVAIS to write the Introduction which 

 precedes the Translation of M. STANISLAS JULIEN. No one was 

 more capable of appreciating the merit of the methods adopted in 

 China, for the cultivation of Mulberry Trees, and the rearing of Silk 

 Worms. Indeed, M. Camille Beauvais has already put several of 

 these methods into practice, and it is to the employing them that he 

 is indebted for the improvement introduced by him in this useful 

 work. 



In the publication of this Translation, with the concurrence of M. 

 Camille Beauvais, the Minister of Public Works, of Agriculture and 

 Commerce, has wished to show him the value which he attaches to 

 his important labors, and to prove, at the same time, to those who 

 raise Silk Worms, that the methods adopted, with so much success, 

 by this learned agriculturist, are worthy of attracting their atten- 

 tion.
