Description

1. Experiments on (1) the flashing types, (2) flamability and (3) flashing time were carried comparatively on leaves among 74 species of common tree. And an attempt of classification on (1) the flashing types and on (2) flamability, i.e. whether or not leaves are prone to blaze up in flame.
2. As the indicator of flamability of leaves the author chose "flashing time", and he carried some tests of this on 74 species of tree, using an electric furnace and a gas furnace.
3. He got a chance to test the fire resistance of plantings in an experimental incendiary fire sponsored by the Architectural Reserch Institute of Japanese Government. He sphced 60 twigs and pieces of dry wood in a three dimensional pattern in front of the window jetting flames 3 m off the building.
4. In this experiment he could get some estimations, such as fresh leaves seem hardly to blaze up unless they enter into the reach range of flame for a minute or more.
