230 FUEL AND HEATING 



chimney of sufficient height to create a good draught, 

 but the chimney should be so situated as not to suffer 

 from natural currents blowing over it, if this can be avoided. 

 Such currents arise from the presence of nearby hills 

 and sometimes cause downdraughts. 



In the choice and use of fuel every precaution should 

 be exercised to see that your good money is not being 

 blown up the chimney. The whole question of the choice 

 of boiler, the heating arrangements, and the proper use of 

 fuel and of careful firing, is one of the most important as 

 to the profit or loss on his business that the grower has to 

 consider. The notes in this chapter are therefore not 

 to be taken as exhaustive, but merely suggestive, and 

 expert advice, or the advice of some one of experience, 

 should be procured before going into any large contract 

 in regard to heating. 



A considerable saving of fuel is effected when the 

 heating is done from a central plant, and the boilers, 

 mains, and other pipes properly placed, and insulated if 

 necessary. Examine occasionally the furnace or combustion 

 chamber to see that it is not getting clogged. Blowing 

 off the steam boiler once a week is advised. A good fire- 

 man means much to the success of any plant growing 

 concern.
