DEATH CAMAS SPECIES, ZYGADENUS PANICULATUS. Lf. 
them by their general appearance and habits. Z. paniculatus has 
thick, spreading leaves, while Z. elegans has thin, grasslike leaves. 
Z. paniculatus grows in dry, somewhat exposed places at elevations 
not exceeding about 8,500 feet. Z. elegans grows in damp places 
in meadows, or along small streams, sometimes actually in the water, 
at others on shady, damp hillsides, and generally in the western 
mountains ‘at elevations above 8,000 feet. So far as the western 
ranges are concerned, Z. elegans might be called the mountain camas. 
EXPERIMENTAL FEEDING. 
Experimental feedings of Z. elegans to sheep were made in the 
summers of 1915, 1917, 1918, 1920, and 1921. No definite results were 
obtained in 1915 and 1918. It appeared later that the dosage in. 
most of these cases was too small to produce intoxication. Inasmuch 
as during these two years exact data regarding loss of moisture in the 
plants used were not recorded, the results can not be compared with 
those of 1917, 1920, and 1921, and it seemed best not to include these 
experiments in the summarized statement of Table 6. In 1917 there 
were 11 experimental feedings of sheep, 8 animals being more or less 
affected. In 1920 there were 21 experimental feedings, resulting in 
9 cases of poisoning and 1 death. In 1921 there were 8 feedings, with 
2 cases of poisoning. Table 6 gives a summarized statement of the 
cases of these three years.
