(ireenhoose Heating. 



INSUFFICIENT RADIATION. 



Will a 2-inch overhead flow supply two 

 4-inch pipes in a house 10x75 feet, with 

 walls four feet high and eight feet to 

 the ridge? The house runs east and 

 weat. There is one foot of glass in the 

 south wall. There are no gables exposed. 

 I wish to have a temperature of 55 to 60 

 degrees. Our weather here in Indiana 

 hardly ever goes to zero. F. C. A. 



While one 2-inch riser will supply two 

 •4-inch pipes seventy-five feet long, this 

 will not provide suflScient radiation for 

 your house to maintain a temperature of 

 60 degrees. In order to carry the tem- 

 perature you desire, it will be necessary 

 to provide the house with a 2^/^-inch flow 

 or riser and five 4-inch pipes, or better 

 still, nine 2-inch pipes the length of the 

 house. ' L. C. C. 



HOT WATER FOR SINGLE HOUSE. 



How shall I pipe, for hot water, a 

 greenhouse 20x60 feet and ten feet to 

 the ridge? There are twenty inches of 

 glass on the sides. The house is exposed 

 on both sides and also at one end, which 

 is of glass. It is partly protected from 

 strong winds. I want a temperature of 

 70 degrees in this Michigan climate. 



R. E. H. 



A satisfactory plan for arranging the 

 heating pipes in your greenhouse 20x60 

 would be to install fourteen 2-inch lines 

 of pipe. Use five lines of pipe — one flow 

 and four returns — under each side bench, 

 and four lines of pipe — one flow and 

 three returns — under the middle bench. 

 This should give radiation suflicient for 

 a temperature of 65 degrees in severe 

 weather and 70 degrees at other times. 

 The high point in each manifold should 

 be at the point most distant from the 

 boiler. By using a well elevated expan- 

 sion tank, connected with the main return 

 close to the boiler, such a system should 

 give good service. L. C. C. 



THE BELL AND THE PENCIL. 



Many a florist has been saved from 

 a crippling loss by the tinkling of a bell, 

 and in places where there is no night 

 fireman the prudent man installs a ther- 

 mostat. The Parker Mfg. Co., Boston, 

 has installed thousands of such for 

 greenhouses, or rather has sold them to 

 florists who have installed them them- 

 selves, so easy arc they to put up. All 

 you have to do, get two cells of battery, 

 Sampson or Le Cleche, and the necessary 

 wire and bell. The thermostat is ar- 

 ranged with binding posts to be connect- 

 »h1 with wires and can be set at any 

 two points on the entire scale, so that 

 the bell located in the owner's sleep- 

 ing-rooms will ring if the temperature 

 goes either below or above the degree 

 wanted. The cost of the whole outfit, 

 and the work of putting it in, is so 

 slight that it has no comparison what- 

 ever with the loss a grower would be 

 subjected to if the contents of one house 

 wore lost by frost, as happened with 

 niore than one grower last winter. 



The better stock a man grows the 

 greater pains lie takes in growing it, 

 and in most of the big i)laces where 

 first-class stuff is titrned out there is a 

 recording thermometer in one or more of

llie lioHses, to show exactly, wliat has 

 taken place < luring the night, because 

 each morning the owner of such an in- 

 strument has pencile*! upon a paper dial 

 a record of the temperature of every 

 minute through the ])reviou8 day and 

 night. When these thermometers first 

 were installed in greenhouses their pres- 

 ence was resenteti by many night men, 

 as indicating a suspicion of neglect of 

 duty, bnt now quite a different view is 

 taken, as these penciled tlials are the 

 strongest testimonial as to a night 

 man 's ability. A good man makes the 

 pencil draw an even line along the de- 

 gree called for, but a careless one causes 

 the instrument to draw a wavy and un- 

 certain mark which looks like a map of 

 the Alps.

The Supply of Mums. 



A few years ago some growers of the 

 <lahlia, which was then the only flower 

 in demand for All Saints' day, said that 

 large chrysanthenuuns couM not be 

 grown around New Orleans. They soon 

 found that .A'ississippi could raise them 

 satisfactorily, and for a few seasons the 

 chief part of the supply for New Or- 

 leans was drawn from that state. Today 

 a great change seems to have taken
