The burning of paper is often used to study the phenomena of fire. The precious investigations of fire of Dr. T. Terada, Dr. S. Suzuki and Dr. T. Kimbara are also experimented by papers.
Author is going to examine the relation between the fire and the burning of paper analysing the influence of cut or preventing hole which is marked in the paper in place of river or road in a town.
Some results have been obtained as the followings ;
(1) The new treatment of experiment is very suitable for this study.
(2) Author get an approximate formula between the velocity of wind and the inclination of desk.
(3) The velocity of flame spread increases the speed by the wind volume.
(4) The velocity of burning decreases the speed from a critical value of the wind volume.
(5) In general, the velocity of flame spread increases the speed by the existence of hole.
But it decreases the speed in special case.
