TVO TEXAS ROSE HOUSES. 



I am building two houses, 30 by 100 

 each, and intend to grovr roses. I should 

 like to ask if ventilation on one side of 

 each house would be sufficient, and wheth- 

 er it is better to hang the ventilators 

 from the header or the ridge f Can 

 smilax and Asparagus plumosus be grown 

 with roses t I intend to use steam heat. 

 How many runs of 1-inch pipe would be 

 necessary to maintain the temperature 

 for roses, where the thermometer seldom, 

 if ever, goes to zero? Which would you 

 prefer — side heat or under the benches t 



aN. 



There should be ventilation in one side 

 wall and on one side of the ridge in each 

 house. It is generally best to hang the 

 ventilators from the ridge. It is not de- 

 sirable to grow smilax in the same house 

 with roses, although it is sometimes done. 

 A temperature of 60 degrees can be main- 

 tained with fifteen 1-inch pipes. It will 

 be vfell to have two under each bench and 

 the remainder on the walls. 



POORLY PLACED, FLOV PIPES. 



I have a hot water system that does 

 not heat my place properly, and I should 

 be thankful if you would tell me the 

 cause of the trouble. I have two houses, 

 each 21x76, running east and west, with 

 a three-quarter span to the south. The 

 walls are of briqk, cemented on the inside. 

 There is no wall between the two houses. 

 There are six benches, and under each 

 bench there are two 1%-inch flow pipes 

 and one 1^-inch return. The boiler is 

 six feet below the ground level, and the 

 1^-inch flows are supplied by a 4-inch 

 main pipe, four or six inches under the 

 ground — that is, a cross-header. The 

 1%-inch flows lead out from this header 

 %o the highest point in the system. Then 

 they fall two and one-half inches in the 

 seventy feet and connect with one return 

 of the same size, which extends to the

boiler with a fall of two and one-half 

 inches in the seventy feet. 



I have no trouble in getting my boiler 

 to circulate, but have to watch it to keep 

 it from boiling. The houses are new — 

 built last summer, with 16x24 glass. Yet 

 when the temperature is 22 to 28 degrees 

 outside I hav,e trouble in keeping it up 

 as high as 50: ^grees inside. My belief 

 is that the pllijes under the benches are 

 not large enough to maintain the needed 

 teq^perature. I am located in Mississippi.

 which affords any idea of the trouble.

Certainly it is not due to any deficiency 

 in the radiating surface, as it would be 

 ample to maintain a temperature of 60 

 degrees in zero weather. Unless the low- 

 est part of the system is two feet above 

 the heater, a rather slow circulation nught 

 be expected in pipes as small as those 

 mentioned. It is possible that, with the 

 slight fall mentioned, there are one or 

 more high points in which the air has 

 pocketed, thus interfering with the circu- 

 lation. In that case, the difficulty might
