DEATH CAMAS SPECIES, ZYGADENUS PANICTJLATUS. 17 



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.
