TTk Florists' Review' 



Iloy^MBBB 1^. lfifi2, 



tell me what is the reason? My loca- 

 tion is western Missouri. B. P. M. 



As neither the temperature desired 

 in the large house nor the area of the 

 surface of the grate is stated, a posi- 

 tive answer as to the capacity of the 

 boiler to heat the houses cannot be 

 given. If the desired temperature for 

 the house 23x75 is not higher than 60 

 degrees, and if the grate has a diameter 

 of twenty-four or twenty-five inches, 

 the heater should answer for the two 

 houses. Nothing is said regarding the 

 height of the boiler as compared with' 

 that of the coils, but it is possible that 

 the trouble is caused by the coils being 

 lower than thfe top of the heater. 



To heat the wide house to 60 degrees, 

 three 2y2-inch flow pipes and twelve 

 2-inch returns should be used. If li^- 

 inch returns are to be used, fourteen 

 will be needed. For 50 degrees, only 

 eight 2-inch or ten IVa-inch returns 

 will be required. If the returns are 

 not much below the top of the boiler, 

 and if one flow is carried on each plate 

 and the other under the ridge, a good 

 circulation can be secured. For the house 

 11x75 a temperature of 40 degrees can 

 be obtained by using one 2%.inch flow 

 and either four 2-inch or five li^-inch 

 returns. 



In case the present flow pipes are to 

 be used, it will probably be advisable 

 to place one on each wall of the 23-foot 

 house and to suspend one under the 

 ridge in the other house. 



THE COAL MARKET. 



While those who are dealing with 

 contracts made earlier in the season 

 may find the situation a little easier, 



r-n i^^i* ^.^° ^^ ^o^°g belated buying 

 still finds himself rather up against it 

 Cars are a little more plentiful, but not 

 enough so to permit the mines to pro- 

 duce more coal than is needed for ship- 

 ment on contracts. Extremely small 

 quantities of free coal are coming for- 

 ward. This is especially true of Poca- 

 hontas and the other smokeless coals 

 so popular for greenhouse use. Large 

 concerns those producing great quanti- 

 ties of these coals and supplying laree 

 growers, find themselves so behind on 

 their deliveries that they have practi- 

 cally no coal to offer for immediate 

 shipment. It may take several weeks 

 to catch up. Unfortunately, the method 

 by which coal is mined and handled 

 does not permit accumulation of a large 

 supply at the mines. It can come out 

 of the ground only go fast as ears are 

 placed to receive it, so that production 

 has been curtailed by the car shortage, 

 and still IB being held down. Also, as 

 soon as real winter sets in the move- 

 ment of cars will become slower and 

 there is little prospect of the mines 

 running full capacity at any time this 

 season. 



PROVIDENCE. 



The Market. 



Business showed a slight increase last 

 week, accelerated by the influx of 

 chrysanthemums, which almost flooded 

 the local market. Big blooms main- 

 tained a. price of from 25 to 50 cents 

 each, while smaller ones sold down as 

 low as 50 cents a dozen. Roses were 

 of good quality and quantity, as were 

 carnations. Weddings furnished much 

 work, while funerals, of which there

find them perfectly satisfactory. We frequently receive re-orders 

 from florists who have tested the^e boilers thoroughly and found 



them even "Superior"
