Experimental Procedure 
Since white snakeroot does not grow in the vicinity of Raleigh, ]NT. C., 
where these feeding experiments were conducted, it was arranged to 
secure daily shipments of the green weed from Shooting Creek, H. C., 
where this plant grows luxuriantly. Since this town is over 400 miles 
distant from Raleigh, the weed used had been collected about 48 hours 
prior to its arrival at Raleigh. The weed was fed twice daily along 
with a maintenance ration of some dry concentrate. In the feeding 
experiments of the present season (1917) this feed was further supple¬ 
mented by timothy hay. The sheep were kept singly in small pens in

animals used were selected from a flock of grade ewes and their lambs,
