40 HAY AND FODDER. 
the time the hay is cut. One man, spoken of by Chesnut 
and Wilcox, used hay cut from a low meadow as winter 
feed for sheep. At the first feeding many of them be- . 
came sick, and the rest of the hay could not be used. Con- 
siderable amounts of Swamp Camas were found in the 
hay, and no other poisonous plants were present. In an- 
other case six cattle were pastured on low, wet ground 
and two of them died. The symptoms were practically 
identical with those caused by Death Camas, and quanti- 
ties of Swamp Camas were found in the stomachs. 
Swamp Camas resembles Death Camas except that it 
is considerably larger and coarser, and grows in more 
swampy situations. As stated above, the ef- 
fects produced by the two species are iden- 
tical. This plant is probably more dangerous in hay than 
Death Camas, because it is larger and forms a greater 
proportion of the feed. 
The Plant 
PEA FAMILY—Leguminosae. 
LUPINES—Lupinus spp. 
Other Common Names: Wild Pea, Wild Bean, Blue 
Pea, Blue Bean, Pea Vine. 
In the west, where Lupines are very plentiful, their 
misuse as pasture and hay has been the cause of im- 
mense losses. Chesnut and Wilcox have 
enumerated a long list of casualties in 
Montana. Two hundred sheep were being 
moved, and were allowed to feed on a 
patch of Lupine. By next morning one hundred of the 
band were dead. Lupine hay was fed to one hundred and 
fifty bucks and as a result of one feed ninety died. Three 
two-year-old colts were fed ordinary hay most of the win- 
ter and then ate Lupine hay for two days, when all died.
