=CONDITIONS SIMILAR TO LOCO-WEED POISONING IN OTHER PARTS OF THE WORLD.=

According to Maiden a condition similar to loco is met with among animals in Australia and is there believed to be due to eating various species of Swainsona. As Maiden says, "Its effect on sheep is well known; they separate from the flock, wander about listlessly, and are known to the shepherds as 'pea-eaters' or 'indigo-eaters.' When once a sheep takes to eating this plant it seldom or never fattens, and may be said to be lost to its owner." Horses, after eating this herb, "were exceptionally difficult to catch, and it was observed how strange they appeared. Their eyes were staring out of their heads and they were prancing against trees and stumps. The second day two out of nine died, and five others had to be left at the camp."
