内容記述（抄録等）
Searching after devices to make easy the maintenance of cleared firebreak strip, the writers tested some wire netting screens, if they might be used as an effective means of checking forest fires.
Across a hillside bush, to be cleared by experimental fires, they developed scrolls of 10-16mesh wire netting screen, to be parallel to the proposed flame front, in 1960.
In these fires, exclusive of ones in extraordinary thick bush, the screen could hold the blaze in check, provided it had no loose seams and no interstice left above the ground. And they observed that flames couldn't get through nettings, by blazing fuels of so light or moderate density as in bush fires.
This screen may be applied in two ways, in proper application:
1) it can complement the cleared firebreak strip, saving the width of strip and/or making sure of checking the fire on hazardous fuels,
2) a seamless wire netting might be applied solely, in grassland or thin bush, to a cardinal firebreak, of which the maintenance shall be much more easy than of conventional ones.
The further studies are expected on the effective size of mesh and the economical construction method of this screen.
