Heating Apparatus 239 



of 9000 ft. capacity, as mentioned above, will require from i to J ton 

 per week if kept cool, or about 1 ton if treated as a stove. In the 

 near future, perhaps, when science will have shown -us how to make 

 petroleum into a solid commercial article for heating purposes, there may 

 be good times yet in store for the grower under glass. In the meantime 

 he must pay the price asked for coal and coke, and see that he engages 

 intelligent stokers to attend to his fires. A good stoker at 80s. per week 

 is better than two bad stokers at 20s. each per week. [j. w.]
