FORCING DEPARTMENT 



ON HEATING HOT-HOUSES, &c. WITH 

 HOT WATER. 



Amongst the numerous improvements that have 

 been lately introduced in horticultural erections, the 

 apparatus best calculated for heating them forms 

 one of no small importance. Since the successful 

 application of steam and hot water for this purpose, 

 the old brick flues are falling rapidly out of repute ; 

 and we may look forward to no very distant period 

 to see these smoke-flues totally expelled from the 

 Gardens, and only used as conductors of the smoke, 

 or in conjunction with the hot water pipes, for 

 economizing fuel and heat. Steam, which is of 

 rather a recent introduction, is not likely to become 

 very generally applied to the heating of Hot- Houses, 

 in consequence of the great expense attending 

 its first application, and the subsequently greater 

 consumption of fuel. The expense, at the first 

 erection, is considerably more than that of flues, or 

 hot water pipes ; consequently, the steam apparatus 

 has been but seldom introduced, except in large 

 establishments, and for the heating of extensive 

 ranges, for which it is unquestionably well adapted, 

 and is perfectly efficacious in the most severe 

 weather, to keep up, to convey to a great distance, 

 and give out, in equality, the requisite degree of 

 heat, through the various compartments in which 

 it is introduced. The system of heating by hot water
