Varieties are known in silk countries, which are pro- 

 duced from the white mulberry, and are only to be ex- 

 tended by layers or by grafting. Of these, Count Dan- 

 dolo prefers those which in Lombardy are called Folia 

 Giazzola, and Folia Doppia. Other varieties of es- 

 teemed kinds, are the Rose leaved, the Roman, the 

 Spanish, and the Small Queen-, all being sub-varieties of 

 the white. 



The Rose leaved bears roundish leaves, of large size, 

 and resembling in form the leaves of the rose. The 

 Roman leaf is distinguished from others, by its very 

 large leaves, some of which are of the size of those of 

 the gourd. The Spanish has a leaf which much resem- 

 bles those of the Wild Rose Mulberry, except being 

 larger, and more pointed, and is extremely hardy. Those 

 of the Small Queen are oblong, tolerable large, and of 

 excellent quality. 



The bark according to Rosier, may be converted into 

 linen of the fineness of silk. For this purpose, the 

 young wood is gathered in autumn, during the ascent of 

 the second sap, and immersed for three or four days in 

 still water. It is then taken out at sunset, spread on 

 grass, and returned to the water at sunrise, and this daily 

 repeated, and finally it is prepared and spun like flax. 



Other fine varieties which are believed to belong to 

 the same species. 



Morus Alba Giazzola. 

 Feuillcs dc Parchemin* 

 Roman Dura. 

 Nervosa. 



Other varieties have been recommended, as one from 

 Italy called Alpine, and another from Constantinople 

 called Broussa, and the mortis expansa, which seems to 

 be identical with the Roman dura ; also the morctti or 

 morcttiana*
