is most prevalent in all parts of the plant, and should, there- 

 fore, be most beneficial. Lime is found in greatest proportion 

 in the stem, and should be most beneficial to the growing plant. 

 Soda is found most in seeds, and should be most useful at the 

 time of ripening. It is evident, also, that such as soda cannot 

 be so much needed, as a constituent, as potash ; though, as a 

 solvent, it is more powerful. Nitrate of soda has been very 

 beneficial to onions this season; its deliquescent property of 

 extracting water from the air may be useful in a dry season. 

 As a knowledge of these things spreads, it may conduce to 

 economy to employ them only when needed ; and the object of 

 fruitfulness may be secured at much less expense. 



Art. II. The Roller called Pica marina in Italy. By Charles 

 Waterton, Esq. 



" I love to see the little goldfinch pluck 

 The groundsel's feather'd seed, and twit and twit ; 

 And then, in bower of apple blossoms perch'd, 

 Trim his gay suit, and pay us with a song. 

 I would not hold him prisoner for the world." Hurdis. 



I KNOW nothing in the environs of Kome half so grand and 

 charming as the ornamented grounds of the beautiful villa 

 Pamphili Doria, the gates of which are always opened to the 

 public. A blessing be upon the head of its princely owner, for 

 this prized permission to the world at large ! May his liberality 

 never suffer by the hand of wanton mischief, or ever be checked 

 by the presence of a rude intruder ! Many a time, when fairly 

 tired with the never ending scenes of painting and of sculpture 

 within the walls of the eternal city, have I resorted to this en- 

 chanting spot, here to enjoy an hour or two of rural quiet, and 

 of purer air : and, could I have had a few British gardeners by 

 my side, the enjoyment would have been more complete ; for 

 gardeners in general are choice observers, to them 



" Not a tree. 



A plant, a leaf, a blossom, but contains 

 A folio volume." 



The marble fountains of Pamphili Doria, its lofty trees, its 

 waterfalls, its terraces, its shrubs and flowers and wooded 

 winding-paths, delight the soul of man, and clearly prove what 

 magic scenes can be produced, when studied art goes hand in 

 hand with nature. The walk, canopied by evergreens of 

 ancient growth, and at the end of which a distant view of 

 St. Peter's colossal temple bursts upon the sight, has so much 

 truth and judgment in its plan, that I ques'tion whether its 

 parallel can be found in the annals of horticultural design.
