CHAPTER YI. 



THE following genera form a great family, or 

 rather alliance : Mulberry and Fig, Nettle and 

 Pellitory, Elm and Celtis, Hemp and Hop. Just as 

 the Eose family, or rather alliance, may be split up 

 into .Rose, Apple, Plum, Bramble (Rubus), Straw- 

 berry, &c. ; so the Mulberry, Nettle, Elm, and Hemp 

 may be considered as separate types, though they all 

 agree in having no petals, and in several other 

 characters. I have joined the Elm and Celtis for 

 convenience. We are particularly well placed on the 

 Riviera for studying this family, because several 

 interesting genera and species are to hand which we 

 cannot examine in England ; the Paper Mulberry for 

 instance, and the Celtis. 



To begin with the Mulberry (Morns) : the tree is 

 stripped to feed the silkworm (Bomby-x Mori) here as 

 elsewhere. The white Mulberry (M. alba) is pre- 

 ferred for this purpose, whereas the fruit of Moms 

 nigra is superior. The wood of the red Mulberry 

 (M. nibra) resists water as well as the best oak, and
