so much larger than that necessary to poison cattle, it was deemed 
conclusive evidence that the plant at this stage is not poisonous to | 
sheep.

EXPERIMENTAL FEEDING OF DELPHINIUM MENZIESII TO SHEEP IN 1910. 
Four sheep weighing approximately 100 pounds each were fed 
various quantities of Delphinium menziesii. Table IX gives a sum- 
mary of these experimental feedings. 
Sheep 113 was fed 32.75 pounds of roots, the feeding continuing 
from June 2 to June 13. On June 13 the available supply of roots for 
feeding was exhausted and the sheep was given the tops, including 
leaves and flowers. This feeding was continued through June 22, 
the animal 'having received, altogether, 50.25 pounds of this material. 
Sheep 125 was fed 111.75 pounds of tops, including leaves, stems, and 
flowers, the feeding continuing from June 2 to June 16. Sheep 119 
was fed from June 15 to June 26, the material being the entire top, 
including leaves, stems, flowers, and seeds. During this time the ani- 
mal ate 101 pounds, or very nearly its own weight. During the 
same period, June 15 to June 26, sheep 123 was fed 73.75 pounds of 
the same material. 
The Delphinium menziesii fed to sheep 113 during the first experi- 
ments of root feeding was collected near the camp. All the rest of 
the material fed to the sheep was collected at Pass Creek Park and 
was of fairly mature plants. The feeding of this plant to sheep pro- 
duced no injurious effect whatever. The animals did not even lose 
much in weight, and that little could be accounted for by reason of 
confinement and the fact that they were being fed but a single 
variety of plant. 
It should be added that sheep 160 ate in one day, on the basis of 
100 pounds of weight, 5.98 pounds, and sheep 177, 6.9 pounds. In 
the experiments of 1910 and 1911 sheep 118 ate in one day 6.7 pounds ; 
sheep 114, 6.5 pounds ; sheep 135, 7.4 pounds ; sheep 134, 7.8 pounds ;
