It is also satisfactory to .spray water against the base of the flames from the rear particularly if there is much smoke. "^ one crew here 'â ^.^'"^TER HEAD FIRE IS CONTROLLED.

Back-firing: When the wind is strong or when the flames are in slash, fallen logs, dead ferns, bracken, or grass, fire becomes so intense that it is unsafe and impracticable to attempt close attack. Back-firing is resorted to in such cases. It should be remembered that fire is a dangerous force and that when fire is fought with fire extreme care and keen judgment must be used. If a fire starts some area will be burned-over and some growtli will be damaged, but in order to reduce the damage as much as possible some additional sacrifice may have to 24 ' be made by starting a back-fire. The area to be covered by the back- fire should, however, be kept as small as is pra
