different stages of their larva existence in the short space 

 of 26 days. The cocoons which were obtained from this 

 second crop were of a much larger size than those of the 

 first crop, but what is of still more consequence they 

 were of the whiteness of snow, and have a most beautiful 

 shining appearance. (See New England Farmer, vol. 

 xi. No. ii.) At Madam Parmentier's in 1831, I witness- 

 ed the silk worms feeding with avidity on the leaves of the 

 Morus Multicaulis, and was informed that they had left 

 eleven other species of mulberries to feed on this. At 

 that place we are also informed, the Morus Multicaulis 

 has withstood the rigors of the last six winters uninjured 

 and unprotected. Although being possessed of an ac- 

 tive and prolonged vegetation, it is not to be expected 

 that the unripened wood of the tender tips should always 

 escape. 



I introduced this plant to Massachusetts in the spring 

 of 1831, from the Messrs Prince of the Linnaean Botanic 

 Garden, Flushing ; I also received plants of the same 

 from Madam Parmentier's of Brooklyn L. I. and I have 

 also received them from France from M. Andre Michaux, 

 author of the American Sylva. 



DANDOLO OR MORETTJ MULBERRY. 



A new and most valuable species of mulberry for the 

 nourishment of the silk worm. It was first discovered 

 about 1815, by M. Moretti, Professor in the University 

 of Pavia, and from a single young tree he had in 1826, 

 multiplied them to 120,000. The tree is presumed to be 

 hardy ; the fruit which is at first violet, becomes at ma- 

 turity perfectly black. The leaf is ovate, sharp pointed,
