1885.] GAILLOrS PATENT AUTOMATIC TORCHES. 159 



ordinary paraffin oil lamps are not needed for the use of this phase 

 of the best modern instance that fire, though a bad master, may be a 

 faithful servant. The reservoir of petroleum spirit in the instruments 

 used by the two workmen of our first diagram, is the round projection 

 just below their hands ; and when the torch is held as by the work- 

 man at B, a few drops come to its tip, which on being lit speedily 

 heat the whole torch, and the spirit vaporizes into the atmospheric 

 air, admitted by an opening at the top of the reservoir behind the 



workman's hand ; so a continuous gas supply is kept up, which may 

 be used as the two workmen at A or B are doing. The flame is 

 entirely under control. By means of a flame protector, young buds 

 escape, when the larvae below them are being destroyed. A 

 perforated cylinder, at X in our second diagram, serves to direct the 

 flame, and protect it against the violence of the wind. When the 

 workman desires to cease operations, as at A and B in our first 

 diagram, the torch is placed in a vertical position.
