250 THE PLEASURE GROUND. 



especially as no deviation whatever takes place 

 between the plants in both, so far as regards soil, 

 temperature, and propagation. 



The plants, cultivated in both departments, are 

 principally natives of the Cape, Japan, New Hol- 

 land, or some other equally temperate climate, and 

 may, therefore, all be treated as Greenhouse plants. 



In the erection of a Greenhouse and Conser- 

 vatory, the form of the house is not of so much im- 

 portance, providing it be placed so as to have the 

 full benefit of the early morning and mid-day sun, 

 in the Winter and Spring months, which is so essen- 

 tial to the welfare and health of the plants. It is, 

 therefore, necessary, that these buildings should be 

 so constructed as to admit of a large portion of light 

 and ventilation, the two most essential requisites in 

 such structures. The sashes should, consequently, 

 be so arranged, that a large quantity of air may have 

 access to circulate in all parts of the house. 



It is, likewise, very desirable that the house 

 should be furnished with the proper means of in- 

 creasing the temperature in severe weather; and 

 whether heated by steam, hot-water pipes, or flues, 

 they should be constructed of such magnitude, and 

 so devised, that the heat given out from them will 

 be sufficient for expelling the frost in very severe 

 weather, as well as for quickly raising the tempera- 

 ture of the house, which is often absolutely neces- 

 sary, when the cold or frost sets in suddenly in the 

 evenings, as this frequently becomes so intense, that, 

 otherwise, many of the more tender species would 

 be hurt before morning. And although many of the
