dangerous poisonous plants and should be known by every 

 stockman, 



BROWN'S 

 (Pcsonia Brownii i Dougl.) 

 PL. XV. 



This plant is well adapted to withstand drouth and changes 

 in climatic conditions. It possesses a number of thick roots, 

 which penetrate the ground very deeply, and make it almost 

 impossible for it to be pulled up by sheep. (See pi. XV.) On 

 the hillsides around Webber Lake it was found quite frequently, 

 where the sheep were seen to eat it quite readily. 



MEADOW RUE. 



{Thalictrum Fendleri, Engelm,) 



PL. XVI. 



This plant has an exceedingly delicate and graceful habit, 

 growing about two feet high. It was found in partly shaded 

 places around the natural meadows on Mr. Talbot's range. 

 Sheep are very fond of it. 



TALL LARKSPUR. 

 {Delphinium glaucum, Watson.) 



This dangerous, poisonous plant was seen quite frequently 

 from Lincoln Valley to Summit Soda Springs. It occurs usually 

 in large patches by the side of creeks in the .valleys. Although 

 sheep do not care for it, yet it is sometimes eaten by them. 

 Sheepmen do not consider it dangerous. Cattlemen, however, 

 are afraid of it, and consider it very poisonous. Mr. Ridinger of 

 the Tehauntepec dairy, about eight miles from Webber Lake, told 

 us that cattle die after eating it, with the following symptoms: 

 Trembling and shivering, succeeded by extreme weakness, which 

 makes affected animals stagger and fall or lie down. Mr. Spencer 

 of Lincoln Valley also ascribes poisonous properties to this plant, 

 and says it has caused the death of several cattle in Lincoln 

 Valley, where it occurs in considerable quantity in the pasture
