Second day night, around 7 o'clock. Temperature stopped at about 300 degrees around from 5:00.
Night 8 o'clock on the 2nd. In order to move to an upper fire mouth,
an air hole is made to a bottom fire mouth, and it is covered.
A shelf board closes a lower fire mouth in this way, and bricks are stacked
in front of the shelf board so that this shelf board may not fall.
It is the same as a former screen.
Between three bricks and shelf boards is opened in this way, and it is
made for air to enter from this space.
The former picture was seen from the top.
All the upper bricks from the 4th brick put close to a shelf cover .
A lower fire mouth becomes such.
From now, firewood will be stoked only from an upper fire mouth.
