aud south and measures 25x87, eight 

 feet high to the eaves and fifteen feet 

 to the ridge. It is heated by an Ideal 

 No. 5 hot water boiler, located at the 

 ncrth end. The top of the boiler is 

 about two feet lower than the return 

 pipes. At present there is a 4-inch flow 

 pipe from the boiler, placed about eight- 

 een inches below the ridge, and there 

 are sixteen 2-inch return pipes, four 

 under each of the four benches. 



Our plan is to remove the 4-inch flow 

 pipe and replace it with two 2-inch flow 

 pipes. We also propose to remove two 

 of the return pipes, one from under 

 each of the center benches, thus reduc- 

 ing tho number of returns to fourteen. 

 Our idea is to get quicker circulation, 

 so as to maintain a temperature of 60 

 degrees in zero weather. With our 

 present system it takes about three 

 hours to get a circulation after the 

 fire has been allowed to become low. 



K. F. C— N. Y. 



The plan suggested in the foregoing 

 inquiry would give a slower rather than 

 a quicker circulation. For the best re- 

 sults not more than 200 square feet of 

 hot water circulation should be supplied 

 by a 2-inch flow pipe, and the proposed 

 arrangement would give about 900 

 square feet, or 450 to each 2-inch flow 

 pipe. 



The amount of glass in each wall is 

 not stated, but from the height of the 

 eaves we infer that there are at least 

 four feet and probably five feet of glass 

 in each wall. To heat a house 25x87 to 

 60 degrees, we would use 1,050 square 

 feet of radiation, and, while 2-inch flow 

 pipes might be put in, we would prefer 

 four 214-inch pipes for flows in a house 

 of this length. Place one flow pipe 

 upon each plate and the others either 

 below the purlins or under the ridge, as 

 will be most convenient. While four- 

 teen 2-inch returns would probably an- 

 swer, better and quicker results may be 

 secured if the sixteen now in place are 

 retained. 



Another way of correcting the diflfi- 

 culty would be to retain the present 

 4-inch flow pipe and use it for supplying 

 the coils under the two middle benches, 

 and put in two additional 2%-inch flow 

 pipes, placing them on the plates and 

 using them to supply the two side coils. 

 In case there is little or no glass in the 

 side walls, will answer if two of the 

 present returns are taken out, removing 

 one from each of the middle coils, and 

 these could be placed on the plates and 

 used to supply the side coils. 



By running all flow pipes downhill 

 it is possible to hasten the circulation, 

 and if the expansion is connected with 

 the highest point in the system there 

 will be no occasion for using air valves.

Roses are not so plentiful as they 

 should be, and some of those arriving 

 are mildewed and of extremely poor 

 quality. However, an occasional ship- 

 ment is fair for this time of year and 

 is snatched up at a good price. Gladioli 

 are in sufficient quantity, principally 

 Francis King and America. There has 

 been a good demand for them. Amer-
