In operating its burner(he Oklahoma Railway Company has eliminated much ofthis trouble by attempting not to destroy the weeds totallyas it moves over a section of track, but to burn them so thatthey will dry and blow away in a few days. Experiencehas developed the fact that intense heat applied for a shorttime cooks weeds, and although they do not differ much in. Oklahoma Railway Companys Weed Burner, Side and End Views Supported at one end of the car on cantilever arms are fiveburners and a sheet-metal apron which deflects the heat tothe ground. On the opposite end of the car a 300-gal. oiltank is installed. Two small tanks are set under the largeoil storage tank to serve as reservoirs for the oil under35-lb. pressure. The quantity of air and oil supplied to all five burners iscontrolled through two valves in the main air and oil linesleading from their respective reservoirs. By forcing theoil and compressed air into a mixing chamber just aboveeach burner and directing the flame with the sheet-metalhood, intense heat is obtained at the ground level. Best re-sults were obtained where the weeds were thick when the appearance from that before burning, twenty-four hourslater they will dry up and blow away. In some instanceswhere the weeds are very thick badly decayed ties do catchfire, and one man accompanies the burn
