THE FLORAL WORLD AND GARDEN GUIDE. 



HEATING PLANT-HOUSES WITH GAS. 



HE proper use of gas in the heating of plant-houses has 

 been sufficiently explained and enforced in the pages of 

 the Floral World, and we have from time to time 

 recommended gas-heating apparatus to the notice of 

 our readers. We cannot now afford space to treat of 

 the elementary principles of this subject, but we must repeat, as 



Wright's Gas-heating Apparatus. 



proper to the occasion, that wherever it is possible, the furnace and 

 boiler should be provided for in a chamber apart from the plant- 

 house, and that the heating of the plant-house should be accom- 

 plished by means of a system of hot-water pipes. Our present 

 object is to inform our readers of the most perfect system of 

 gas-heating apparatus we have hitherto become acquainted with, 

 the inventors and manufacturers of which are Messrs. Wright and 

 Co., 30, Broad Street, Islington, Birmingham. As will be seen by 

 the anuexed figures, which really do not require explanation, Messrs. 

 Wright take the very safe course of following the general scheme 

 of what may be termed the orthodox hot-water system, and the only 

 difference between their method and that of the ordinary upright 

 conical boiler is that the heat is derived from a gas flame instead of 

 from a coke fire. One special advantage this system certainly has, 

 and that is the large extent of radiating surface of the hot-water 

 pipes, which does away with the necessity of " driving" on frosty
