THE HEATHERY. 



I In sand on the lower plains, frequently on spots abounding 

 j with natron. ° 



J 



In loam, with iron pyrites, on the exposed plains and second- 

 -ary mountains, enduring drought at times for several months. 



Decomposed schistus, on the stream in deep shaded glens. 



I In stiflf loam and margins of woodlands, moist glens, &c., sur- 

 r rounded by various Pelargoniums, Scirpoidae, &c. 



The soils in which the plants of the first and fourth of the above 

 sections are found, approach nearly, Mr. Bowie observes, to some of our 

 soils, but not precisely ; he adds, that with the exception of those in 

 the above two sections, no bog earth is wanting : it only, in liis opinion, 

 serves to weaken their growth, whereas a good sandy loam would strengthen 

 them, and insure good flowering plants for years. 



WATER. 



Soft water alone should be used for watering plants of every denomina- 

 tion : that from a pond or large river, or such as is collected in cisterns 

 from the roofs of buildings, to be preferred. AYater pumped from wells, 

 and such as may be procured from springs, should be exposed for as long 

 a period as possible to the action of the sun and air before it can be usefully 

 apphed to plants. Water impregnated with mineral matter, such as 

 iron, salt, &c., should be carefully avoided ; and that containing much 

 calcareous matter is injmious to many plants, and to none more so than 

 the genus Erica. . 



SHIFTING, OR POTTING. 



Early in spring appears, from practical observation, to be the most 

 proper time for shifting or potting plants of this order that they may 

 make roots during summer : but to this rule there are some exceptions, 

 namely, the state of health of such individuals as require shifting into 

 other pots at various periods of the year. All plants whose roots have 

 completely filled the pots, and whose balls are hai'd in consequence.
