492 Notices of Communications to the Society, of which 



Mr. John Anderson, Gardener to the Earl of Essex 

 at Cassiobury, communicated in a letter to the Secretary, 

 dated the 5th of November, his method of growing Early 

 Celery. He forms in the ground a trench six feet wide 

 and one foot deep ; into this he puts six inches of rotten 

 dung mixed with a little road grit, and mixes the compost 

 well with the soil by digging it together ; the Celery is then 

 planted in cross rows six inches apart, and eighteen inches 

 from row to row ; as the plants advance they are earthed 

 across the trench. By this means a much larger quantity of 

 Celery can be grown in the same space of ground than in the 

 usual way; but the method is only applicable to Early 

 Celery, for late crops so grown would be liable to rot and 

 perish. 



M. Pronville of Versailles, in a letter to the Secretary, 

 received on the 17th of December, communicated some obser- 

 vations respecting the grafting of Roses as standards, on the 

 Wild Rose or Eglantine of the French, which is practised 

 very much in the French nurseries. Mr. Pronville has 

 observed that some of the most beautiful varieties lost their 

 improved colours and returned to their primitive state, if 

 kept on their own roots. He instances the Felicite, a beau- 

 tiful variety of the Rosa Damascena of Lindley, which only 

 retains its white variegation when grafted. The Clementine 

 of Decemet, a variety of R. rubiginosa, and the R. sulphurea 

 minor, are under the same circumstances, so that other advan- 

 tages, besides placing the flowers at an agreeable height from 

 the ground, results from this practice, which is now also 

 becoming common in England.
