ON TIIK UNION OF KMURVOS, 



graftorfl find that old wood is very difficult to operate upon. It is by the young tisBuo, 



when first growing, soft, tender, suc- 

 culent, and rich in azotized matter, 

 that junctions are effected. Is it not, 

 then, highly prohahlo, that if embryos 

 are to be grafted on each other, the 

 union must take place between the 

 surfaces of the young radicle and the 

 tender lengthening stem when first 

 bom ? We think so. And upon that 

 supposition, it may be a question 

 whether the operation now under dis- 

 cussion may not be most easily and 

 certainly performed by allowing the 

 embryos to enter upon the early stage 

 of germination before they are finally 

 tied together. 



Suppose a couple of orange pips 

 were allowed to grow just long enough to be handled, and then had, in each case, one of 

 the cotyledons removed, so that the nascent stems could be secured to each other with col- 

 lodion, or a film of India-rubber, or some such elastic matter. We only throw this out as a 

 suggestion.
