Branding Fluids

“QF the branding fluids used last year, one of the experimental fluids from the Wool Industries Research Association gave the best results,” says a report presented to the board of governors of Canterbury Agricultural College, Lincoln, yesterday. % “One of the experimental lots made at the college from casein, ammonia, lamp-black, and oil gave almost as satisfactory results. In a scouring trial, however, it was not completely removed, but it is almost impossible to imitate in an experimental scour the action of a commercial scouring on account of the rake action in the bowls. “The work has been continued again this year. An attempt was made to utilise skim milk as a source of casein, but this has been definitely useless, due, no doubt, to the low percentage of casein in a big bulk ot liquid. For our experimental fluids, bright, red iron .oxide was used as a coloring pigment in place of lampblack, and whether because of this fact or not our own experimental fluid has not been so successful this year. “In addition, samples of experimental fluids received from Torridon were distributed to interested people in wetter districts in the North and South Islands to find out how they behave muter different climatic, conditions.
