port of silk worms, is in hedges with low stocks. M. 

 Barthere of Toulouse in the South of France, who has 

 considerably extended their cultivation, fully coincides in 

 the same opinion ; and is confident that in grounds and 

 vineyards which could hardly give two per cent, this tree 

 will now insure ten per cent. 



This tree, according to M. Perrottet and Dr Deslong- 

 champs, is easily propagated either by layers, by cuttings, 

 or even by cuttings of a single eye, placed beneath the 

 surface and shaded from the noonday sun. 



The experiments instituted at Paris by Dr Deslong- 

 champs, have confirmed all that had been previously as- 

 serted respecting the quality of the silk produced by this 

 plant ; he has further stated that the cocoons, made by the 

 worms fed only on this plant, are even rather heavier. 



Dr Felix Pascalis in an article in Silliman's Journal of 

 Science for July, 1830, after informing us that in the 

 preceding March he had received two plants of this mul- 

 berry from France, has added ' After the discovery of 

 this plant, a doubt no longer exists, that two crops of silk 

 may be raised in a single season.' 



At Madam Parmentier's Horticultural establishment, 

 two crops of silk were produced in the summer of 1832. 

 The first were fed promiscuously on the Mortis Multicau- 

 lis, Morus Alba, and other mulberries. The cocoons thus 

 produced were about two thirds white and the remainder 

 of an orange color. A suitable portion of these cocoons 

 were collected for seed, having no regard to color : These 

 being subjected to the hatching process, produced a sec- 

 ond crop the 30th of July. These last were fed exclu- 

 sively on the Morus Multicaulis : they passed through the
