perfpire more than in a cold one ; fo in a warm they require 

 much, and in a cold one little moiflure. Therefore, when tranf- 

 planted from a warm to a cold climate, they fhould have a dryer 

 foil, and from a colder to a warmer, a moifter one, than their 

 native ftation. 



In the firft cafe, not being able to perfpire the fuperabun- 

 dant moifture, they will be rotted ; and in the laft, not having 

 moifture fufficient to fupply the lofs by perfpiration, the growth 

 will be flow, difeafe and death will follow, unlefs they receive 

 a timely fupply of moifture : by the red or yellow colour of the 

 leaves we mjy difcern the approach of the firft evil, and by the 

 flunted growth, and fmall curled leaves, that of the laft. A 

 large quantity of pure circulating fluid feldom injures plants, 

 but ftagnant water is certain deftrudion to almoft every ve- 

 getable. 



After having determined the moft fuitable foil, we muft 

 afterwards ftrive to give each plant a proper fituation. It is 

 well knovsrn, that plants from a fhady will not thrive well in an 

 open, nor plants from, an open in a fhady fituation. But tl^e 

 necellity of a natural fituation is by no plant more evidently 

 illuftrated than by the common myrtle (Myrtus Communis;. 

 Even at Glenarm, in the latitude 54." 56' N. it grows with great 

 l-axuriance contiguous to the fea, and braves our coldeft winters ; 

 yet all attempts to aaturalize it in an inland fituation, feveral
