XV. On the Culture of the Mulberry. By Thomas Andrew 

 Knight, Esq. F. R. S. $>c. President.

Th e Mulberry has not, I believe, been ripened by artificial

 a place in the forcing-house. It is, however, a much finer, 

 fruit when ripened under glass, in the north of Herefordshire 

 at least, than in the open air ; and in the still colder parts of 

 England it is probably the only means by which it can be 

 ripened at all. 



I have stated in the first Volume of the Horticultural 

 Transactions* that dwarf-trees of this species of fruit, which 

 will become productive at three years old, may be readily 

 obtained by grafting a young stock, by approach, with the 

 bearing branch of an old tree; and I have subsequently 

 gathered, in one season, more than twenty dozen Mulberries 

 from a plant not three feet high, and growing in a pot. I 

 have since had reason to believe, that plants which will bear 

 fruit at three years old, and subsequently, may as readily be 

 obtained by laying, in pots raised upon poles of proper length, 

 parts of the bearing branches of old trees ; for I observe, that 

 plants, which I thus obtained a year ago, present all the 

 characters of bearing trees, and will, I entertain very little 

 doubt, afford fruit as soon as those obtained by grafting.
