upon the importance of anmially pruning trec3, [or these reasons; and 

 a gentleman, recently returned from an extensive tour through Europe 

 and the East, states, that the cultivators of silk, particularly in Syria, 

 were unanimous as to the superiority of the silk produced hy worms fox\ 

 on the leaves of trees annually pruned, over that made hy worms nou- 

 rished by trees, the growth of which was unrestrained. The A-meneau 

 cultivator is urged to attend to this hint, whether he feeds silkworms 

 on the native or foreign tree. 



The white mulberry trees which have been planted in Massachusefts 

 and New Hampshire, grow well, and are not injured by frost."* They 

 have not yet been introduced into Maine, but there is no reason to 

 doubt their flourishing in that State, and also in Vermont. Should, 

 however, the cold prove injurious to them, the Tartarian muli>?i-rv, 

 which is cultivated for silkworms in the silk-rearing province o-f Zac- 

 syn, in Russia, might be easily introduced, t 



There are several varieties of the white mulberry tree, two of which 

 have white berries, one red, and the other black. X There are two 

 varieties in the leaf; one has a leaf deeply indented, and supposed to 

 contain little nourishment; the leaf of the other is larger, and not much 

 indented, nor lobed. The common grafted mulberry is a varictv of 

 the first of these two, and itself comprises the following varieties: 

 1st, with white berries; 2d, with red berries; 3d, with black berries; 

 4th, with a large leaf, called the mulberry of Tuscany; 5th, with a 

 middle-sized leaf, dark green, called faglia giazzola; 6th, with a 

 small leaf, of a dark color, rather thick, called double leaf, more diffi- 

 cult to pick, and the best calculated for silkworms. § Besides these, 

 there are numerous other species and varieties in Europe, the result of 

 cultivation; but the detail of their names, and their description, would 

 he useless. A late French writer, and a practical man,|| after having 

 taken up severaiJ pages of his work in describing them, decides in fa- 

 vor of those called Colombasse and Colombassette, as being favorable 

 to the health of the silkworms, and as yielding the greatest quantity 

 and the best quality of silk. The leaves are small, thin, light, and 

 silky. The fruit, when at full maturity, is yellowish, and very large. 

 He also approves of the species called the rose mulberry; the leaves of 

 which are larger, and of a deeper green than the preceding species: the 

 fruit is reddish, and as large as that of the other soecies.ll

T Mr. William Prince, of Flushing, Long Islnnd, has imported from Europe, and 

 has for sale, several of the most ap^iroved varieties of the wliite mulbciry tree. A 

 valuable addition to the stock of mulberry trees already in the country, has been re- 

 cently made by Mr. F. Dusar, of Philadelphia, who opened a subscription for ths 

 purpose, and imported 400 young trees and 1000 plants from the South of France 

 The name of the species was not mentioned bv his coircspondcut.
