the different trees used, and their effects upon the produce 

 of the worm, viz. 



Varieties causing the production of particularly fine silk. 

 Ditto causing the production of silk of a coarser tex- 

 ture. 



Ditto causing the production of very strong silk. 

 Ditto producing a greater quantity of silk. 

 The enumeration of the varieties used in the south of 

 France is as follows : 



AZorus macrofihylla, or grosse-reine. 



rosea, or feuille -rose. 



fasciniata. orfeuiltes decoufices* 



lobata, or feuilles lobees. 



i' oblongata* or langue de b&uf. 

 ovalifotiai or Romain. 



nanci) or nain. 



* italica, or bois rouge d* Italic. 



r Constantinople. 



In other parts of France they also enumerate, la reine, 

 la feuille d'JZs/iagne, and la feuille de Flocs^ but there is 

 little doubt that these local names apply also to some of those 

 before enumerated. 



When the great ease with which this tree can be culti- 

 vated to an almost interminable extent is taken into con- 

 sideration, in connexion with the immense national import- 

 ance which must attach itself to the manufacture of silk, if 

 not wholly, at least in a measure, to supersede its extensive 

 importation, the permanent establishment of such manufac- 

 tures could not fail to be considered as forming as great an 

 epoch in the history of this country, as its first introduction 

 did in that of France. Another gre.it consideration is, that 

 while the rearing of silk may be pursued in any part of the 

 Union, it seems to be particuiaiy adapted to the Southern 

 States, and it will be doubtless there found to flourish most; 

 and our government may, by fostering and protecting this 

 species of manufacture in that portion of the Union, form a 

 counterpoise to that degree of protection which it has 

 thought proper to extend to the manufactures of the Eastern 

 and some of the Middle States. 



CHESTNUTS. 



These will thrive in any good soil, and a number of varie- 

 ties are enumerated in Europe suitable for the table, but
