The Wcckdy Florists' Review.

water tank would be helpful, it will not 

 make any great difference, provided the 

 service pipe is of good size. 



As a fertilizer, use upon each bed 

 about twenty pounds of a preparation 

 mixed in the following proportions: 

 Fifty pounds of nitrate of soda, 150 

 pounds of dissolved bone or acid phos- 

 phate, and fifty pounds of sulphate of 

 potash. The fertilizer should be thor- 

 oughly mixed with the soil to the depth 

 of six inches. 



STOCK FROZEN IN QREENHOUSE. 



We met with a loss during the Jan- 

 uary cold wave. One house was frozen 

 badly. The cold weather was accom- 

 panied by a terrific wind and our west 

 house was frozen in spite of all the 

 firing we could do. Now we are send- 

 ing you a diagram of our houses, show- 

 ing the arrangement of the piping, and 

 we wish to know whether it should be 

 necessary to put in more pipes, in this 

 Ohio temperature. We are going to 

 put in a larger boiler this summer, and 

 if it will be advisable to put in more 

 piping we shall do so. W. S. L. 



The diagram shows one house twenty- 

 two feet wide, with two 2-inch overhead 

 flow pipes and sixteen 1-inch pipes un- 

 der the benches. The other house is 

 sixteen feet wide, with two 2-inch over- 

 head flows, one flow under the bench 

 and fourteen 1-inch returns. Neither 

 the letter nor the diagram gives any 

 idea of the length of the houses, or in- 

 dicates whether steam or hot water is 

 used for heating. Neither is there a 

 statement of the temperature required 

 or the class of plants grown in the 

 houses. If steam is used there is am- 

 ple radiation for 65 degrees or more in 

 each house, and, so far as can be deter- 

 mined, the arrangement should give 

 good results. In case hot water is used 

 for heating the houses, the amount of 

 radiation should be suflBcient to main- 

 tain 50 degrees in the wider house and 

 55 degrees in the other house, except 

 that the pipes are too small, and if the 

 houses are more than fifty feet long, 

 there should either be more flow pipes 

 or they should be of a larger size. 



For the house twenty-two feet wide, 

 if it is not more than 100 feet long and 

 a temperature of 60 degrees is desired, 

 use three 2i^-inch flow pipes and twelve 

 2-inch returns. In the 16-foot house 

 two 21^-inch flows and eight 2-inch re- 

 turns should answer. This estimate is 

 based on the supposition that tbe houses 

 are well built and that there is no glass 

 in the outside walls. There should be 

 an additional return for each two feet 

 of glass. Run all of the pipes down- 

 hill and connect the expansion tank to 

 the highest part of the flow pipes.

A Steady 

 Pressure 



will always 

 be main- 

 tained in 

 vour steam pipes, no matter 

 now the pressure at the boiler 

 fluctuates, if you equip your 

 main lines with these valves. 

 Carry 40 or 50 pounds pressure 

 on the boiler, set the 



Hughson 

 Regulating Valve 



to carry 5 or 10 pounds on the 

 line and you will always have a 

 reserve in case of a sudden drop 

 in temperature. This valve 

 saves both fuel and worry. Ask 

 for catalogue and particulars.
