GENERAL REVIEW. 



gated by grafting either on the Limonia stock' or on seedlings 

 of the common kinds. Seedling Lemons are found to be more 

 vigorous, to grow faster, and to make better stocks than Oranges. 

 Seeds taken from imported fruit grow freely if sown in moist 

 earth and placed in a warm greenhouse or vinery ; and these 

 may be splice, whip, or side grafted in a close case in heat at 

 almost any time : preference, however, should be given to the 

 early months of the year, when vegetation is most active.

may be readily grafted in a close case, as recommended for 

 Gardenias. A gentle bottom-heat of 80 to 90 is necessary ; 

 and the stocks should be placed in heat a week before grafting 

 takes place, so as to facilitate the success of the operation. 

 Side-grafting under the bark answers well, or splice-grafting if 

 both stock and scion are young and slender. Cuttings of the 

 young wood root freely in heat, and soon form blooming plants 

 if potted in loam and sand and placed in a light airy plant- 

 house. Nearly all the so-called species succeed as scion and 

 stock, and cross-fertilisation has doubtless played an important 

 part in producing the numberless varieties and races which 

 exist in this family.
