after four and a half months' daily wear, show no sign of burning away. 

 Flat bars, one fourth inch by one half inch, or even by two thirds of 

 an inch, might perhaps resist fire better, if the one-fourth-inch round 

 bars burn away. The bars are so arranged that, if one fails, it can 

 easily be renewed. I have round bars about one third of an inch in 

 diameter at present on trial in my kitchen-range.

Rule XL " There should be a rim one inch or one and a half 

 inch in depth round the lower insertion of the vertical bars " (Fig. 

 3). The object of this is to conceal the ash at the bottom of the fire, 

 and to enable the front cinders to burn away completely by protect- 

 ing them from the cold air. This rim (F) contributes greatly to tidi- 

 ness, and as a rule will prevent the need of any sweeping up of the 

 hearth during the day.
