TROUBLE WITH HEATER. 



I have a greenhouse 15x28 aud heat 

 with hot water, the boiler 24x42 inches, 

 set two feet below the ground level. 

 The supply tank is four feet above the 

 boiler. I use about 200 feet of li/4-inch 

 pipe. It all has a fall except one stretch 

 of twenty feet. The return pipe and 

 the supply pipe enter the boiler at the 

 same place. When I get up good heat 

 the tank will overflow through reaction, 

 but we have a faucet where we draw the 

 water out of the pipes and stop the over- 

 flow. What is the defect? A. W. 



Small heating plants such as you have 

 are more difficult to regulate than are 

 more extensive ones. The temperature 

 rises and falls more quickly and as a 

 result a larger space in proportion must 

 be provided for expansion than with 

 more extensive systems. I believe that 

 a part of your difficulty can be over- 

 come by combining all the returns into 

 one or two pipes and connecting them 

 with the bottom of the boiler. There 

 must be openings provided for admit- 

 ting the returns near the base of the 

 boiler. Place a tee in the return eight 

 to ten inches from the point where re- 

 turn enters boiler and carry a %-inch 

 pipe up as high as the boiler room or 

 greenhouse will permit, ten or twelve 

 feet if possible, and to this attach a 

 fifteen-gallon steel tank similar to those 

 used for storing hot water in dwellings. 

 Attach an overflow to this tank, which 

 will connect with the down spouts or a 

 drain. A tank of this size should be 

 sufficient to hold the expansion of a 

 plant the size of the one you have. If 

 the expansion tank used is an open one 

 a float can be arranged in it for open- 

 ing and closing the draught of the 

 heater. When the fire gets high enough 

 to cause the water to rise in the ex- 

 pansion tank the float will be lifted afld 

 close the draughts and dampers and 

 when the water returns again to its 

 proper level the draughts and dampers 

 will open with the settling of the float. 



I am not able to criticize the system 

 of piping from the description given, 

 but it is never wise to have hot water 

 pipes on a level for any considerable 

 distance. L. C. C. 



NERINES. 



Among autumn flowering greenhouse 

 bulbous plants there is no doubt the ne- 

 rines rank first. Their culture is simple, 

 they are easily propagated, and they are 

 equally as useful for cutting as for dec- 

 oration, as their long stems make them 

 extremely useful for vases, etc., and the 

 predominant colors being rose or pink, 

 they never fail to please. 



Nerines are old favorites with some, 

 but have never seemed to gain headway 

 to the extent they should do, probably 

 owing to their supposed shy flowering 

 propensities. The chief point in suc- 

 cessfully flowering nerines well is their 

 subjection to a thorough scorching in 

 the sun soon after they become dormant, 

 and for this purpose I reserve a frame 

 for them and they remain in this, with 

 little ventilation and no water, until 

 about the middle of August, when they 

 are taken out and placed in a green- 

 house to throw up their flower stems. 

 When the flower stems appear weak, 

 liquid manure once a week is given, 

 and is very beneficial. As leaf growth 

 commences, watering is increased until 



the growth shows signs of maturity, 

 when it is gradually reduced until the 

 bulbs are quite dormant, when it is 

 withheld. 



Where a number of offsets are to be 

 grown on to flowering size, I have adopt- 

 ed the planting-out system with decided 

 success. A frame is selected where a 

 minimum temperature of 40 to 45 de- 

 grees can be maintained, , and a maxi- 

 mum of 50 degrees not exceeded. Good 

 drainage is provided and covered with 

 loam, leaf-soil, and sand in equal parts 

 to the depth of six inches. In this the 

 young bulbs are planted, three inches 

 apart each way, with their crowns just 

 showing above ground. I have this sea- 

 son lifted a fine batch of nerines, which 

 were treated in this way. 



The great advantage one gains in grow- 

 ing nerines in this manner is that bet- 

 ter bulbs are produced in less time than 

 when grown in pots, and there is a con- 

 siderable curtailment of labor. 



There are about a score of species 

 and many varieties of nerines, but all 

 are worthy of cultivation, and will well 

 repay any labor bestowed upon them. —

AtulUta, Ga. — Benj. Gillespie, fiorist 

 at Grant park, has resigned to resume 

 his old position as gardener at Oakland 

 cemetery. 



Unadilla, N. Y.— N. H. Padgett 

 was completely burned out on February 

 2. Three greenhouses, office, work room 

 and all the contents were destroyed, 

 with no insurance. Mr. Padgett says 

 he cannot rebuild before spring but he 

 expects to start again at the bottom Of 

 the ladder.
