from lupine poisoning, and during the winter of 1898-99 over 

 3,600 deaths occurred from eating lupine hay. 



SILVER-LEAVED LUPINE, OR PEA-VINE. 



{Lupinus argenteuS) Pursh.) 



This valuable forage plant was found on Van Buren's Mount 

 Lola range, where it occurred in large patches, sometimes dense 

 enough to be cut for hay. It was seen to be greedily eaten by 

 the sheep. In some places the flowers had been bitten off and 

 left on the ground, but this did not seem to be a customary 

 habit with the sheep, and^was probably caused by the eagerness 

 of the sheep in the rear pushing the others on. It was without 

 doubt the principal forage plant on the range. Mr. Van Buren 

 valued this plant very highly and had protected it against 

 extermination by not overstocking his range and by feeding the 

 sheep only a short while on any one patch. 



SAGEBRUSH LUPINE, OR PEA-VINE. 



{Lupinus lepiduS) Dougl.) 



This species of lupine was found abundantly in the sage- 

 brush country around Newcomb Lake, Nevada, where it was 

 noticed to be about the only plant not eaten by the sheep during 

 the first week in June. All other plants except the sagebrush 

 were cropped closely, while this lupine was left untouched. This 

 is not easily accounted for, as our experience with all other 

 lupines gathered throughout the summer was that sheep are fond 

 of them. It may be that at that time of the year it is not palatable. 



SLENDER LUPINE, OR PEA-VINE. 

 (Lupinus calcaratus, Kellogg.) 



This slender lupine was found abundantly in large scattered 

 patches in the Webber Lake region, where it was seen to be 

 greedily eaten by the sheep. It appeared at its best in rather 

 shaded locations under the pine trees. The plant is too deep- 

 rooted to be torn up and destroyed by sheep feeding on it. 

 Around Reno and Verdi, Nevada, it is found quite abundantly 

 among the sagebrush on the foothills.
