Theke is no change in the situation 

 in the coal market. The miners have 

 voted overwhelmingly to go on with the 

 strike and there is no immediate pros- 

 pect of the resumption of operations in 

 the Illinois fields. The only sure thing 

 in the coal business is that scarcity and 

 high prices will rule the markets this 

 winter. Growers should not lose a mo- 

 ment in filling their sheds to their great- 

 est capacity. 



STEAM FOB TWO HOUSES. 



I enclose a sketch of a proposed 

 steam system. You -would greatly 

 oblige me by your criticism of this 

 system." I -wish to maintain a tempera- 

 ture of 60 degrees in coldest Chicago 

 ■weather. There are two houses, one 

 27x100 and the other 29x100. The 

 walls are seven feet high to the gut- 

 ters, and three of the gables are 

 exposed. I intend to use a 2i^.-inch 

 pressure reducing valve and a No. 1 

 Morehead trap. The boiler is forty-five 

 horse-power. P. R, 



The sketch shows fifteen 1%-inch 

 pipes in each of the houses, and, count- 

 ing six feet of radiation for each foot 

 of glass for 60 degrees, this seems 

 ample for the purpose. The method of 

 arranging the pipe under the benches 

 distributes it quite evenly and should 

 give good results. 



OBEGON CABNATION HOUSES. 



I have two small greenhouses, each 

 20x60, for the growing of carnations, 

 and am installing in them a hot water 

 plant, with four 2-inch returns in each 

 house, carried along the benches. Would 

 it be better to use a 2% -inch or a 3- 

 inch flow, under the ridge, in each 

 house f A. P.

The 'ideal'' Hot Water Circulator 



THE *'IDFAL" is tho simplest and most efficient circulator on the 

 market; requiring less power to operate than any other.

THRUST BAU. 

 BEARINQ8 



Sectional Cut of Improved Circulator No. 6. 



Some Advantages of the ** Ideal'* Circulator. 



(1) Improves to perfection the circulation in hot water plants that are de- 

 fective. 



(2) Enables present hot water systems to be extended to a very large extent 

 without increasing the size of the pipes or the beight of the circulating bead. 



(3) Owing to the reduced size of the main piping required, it considerably re- 

 duces the first cost of installation. 



(4) Gives an even temperature in the pipes throughout the system. 

 Reduces the amount of radiating pipes required. 

 Enables smaller piping to be used.. 



Piping may be placed below boiler level as well as above. 

 Effects a large economy in cost of fuel. 

 Requires a very small amount of power to operate (1-10 of one horse power 



Is suifflclent for 5,000 sq. ft. of beating surface). 



(10) Can l)e used as an auxiliary to giavity system, and does not Impede the 

 flow of same at times when forced circulation is not required.
