Right: Looking into one of the fireboxes. The twin throat arches for this firebox are on the right, and one of the end hobs and the centre hob can be seen.

The usual practice for Bourry fireboxes is to have end hobs only. The margin for error in cutting stoking wood to lengths is then the width of one hob, as anything longer will have to be placed at an angle or will not fit at all, and anything shorter could fall down at one end and partially block the throat arch. A wider range of lengths can be used if the centre hob is introduced.
