bursting, while any possible mishaps to the hot 

 water system would be mere trifles. My exper- 

 ience as a florist is precisely the opposite, and I 

 dare say I stand by no means alone. I have had 

 hot water pipes burst so seriously that the re- 

 pairs necessitated the complete stoppage of cir- 

 culation, in fact the emptying of the pipes, and 

 the mere good fortune of a inild spell of weather 

 at the time, alone saved the contents of 12,000 

 feet of glass from utter destruction. Now sup- 

 pose such an accident, however unlikely, had 

 occurred to steam apparatus, what would have 

 been the consequence ? You would merely shut 

 off* that one pipe by its supply and condense 

 valves, take apart the nearest union and repair 

 the damage at your leisure, while all the other 

 pipes in your house are working just as usual. 

 We do occasionally hear of steam pipes bursting 

 under high pressure, but have you ever heard of 

 any doing so at a pressure of 20 or 30 pounds, 

 (which you seldom exceed in the most bitterlj^ 

 cold weather) when they are or ought to be 

 tested to at least 150 pounds ? 



Your boy or laboring man cannot neglect his 

 duty with(»ut receiving a warning. If you can- 

 not trust his intelligence, let your foreman or 

 yourself set the damper-regulator to whatever 

 pressure experience will teach you is necessary 

 for a certain temperature, see that your maga- 

 zine is filled, and he can do no mischief except 

 by intentional malice, against which, your hot 

 water apparatus is as little proof a« any other. 



With steam heating you are absolutely in the 

 position to laugh at Jack Frost, while with hot 

 water, unless you put in far more pipe than you 

 need in average cold weather, you are at the end 

 of your string when you bring your water to the 

 boiling point. With steam you simply add a 

 pound or two more to the pressure with the 

 comfortable ^issurance of a snug little reserve 

 force of forty or fifty pounds, which you may 

 use with perfect safety, but which are never 

 called upon. Mr. S. says that steam has never 

 proved effectual for horticultural purposes, as 

 far as he knows, and has been abandoned wher- 

 ever tried. I venture to say without fear of con- 

 tradiction, that in every such instance (and 1 

 have heard of one myself through Mr. Peter 

 Hendei-son) the cause could be plainly demon- 

 strated to be a violation of quite well understood 

 scientific jtrinciples in the construction of such 

 apparatus. I know of two extensive florists' 

 establishments in Chicago heated by steam, giv- 

 ing entire satisfaction, although they were, in 



my opinion, far from being perfect in construc- 

 tion I might easily still more enlarge upon the 

 advantage of steam over hot water, but I feel 

 this comnuuiication is already much longer than 

 I iniended, and for which Mr. Editor, I crave 

 indulgence both from yourself and 3'our army of 

 readers.
