niof. The next house, the middle one 

 of the three, is 30x236 and contains a 

 total of 11,000 square feet of glass. The 

 third house is 25x225, with a total of 

 9,500 square feet of glass. The boiler 

 room and office adjoin one end of this 

 house, and connected with the office is 

 the fourth house, which is 25x90 and 

 contains 3,500 square feet of glass. 



Will you kindly inform me as to the 

 best way of piping these houses for 

 steam? I have been heating the old 

 houses with hot water, and therefore 

 have a lot of 2-inch pipe which I wish 

 to use. What size of leader will be 

 required from the boiler to the new 

 house 50x240f The boilers are seventy- 

 two and ninety horse-power, respect- 

 ively. The houses contain solid beds, 

 sixteen inches high. L. C. 



ft will be advisable to use a 4-inch 

 leader to the house 50x240 feet. To 

 hiat this house, use six 2-inch flow pipes 

 »r.i\ fifteen l^^-inch returns. In the 

 house 30x236 feet use four 2-inch flows 

 and eight I'^-inch returns. The house 

 tl; it is 25x225 feet can bO' heated by 

 m atis of three 2-inch flows and seven 

 I'rJDch returns, and the house 25x90 

 f' t can be heated by means of two 

 fl .V3 and eight returns. As the houses 

 li e solid beds, most of the returns 

 s' uld be on the walls in the case of 

 tl 'narrower houses, but it will not be 

 «• usable to attempt to have more than 

 ♦1 ee returns connected with a 2-inch 

 fl' V pipe in the longer houses.

FLORISTS everywhere are using^ Morehead Steam Traps. 

 A Morehead Return Trap installation is a proven eco- 

 nomic investment. It purges your steam heating lines 

 of all condensation, returning it direct to your boilers as pure, 

 hot feed water. 



The resulting uniform temperature in all parts of the houses 

 insures a better growth of stock, and a saving in fuel, water 

 and labor sufficient to pay for the installation in a few months. 



A complete proposition and descriptive catalogue 

 will be mailed on request.
