A very abundant grass in meadows at middle elevations. In the Sacramento-^Miite 

 Mountain region this is known as "sleepy grass, " and is said to have a narcotic effect 

 upon animals that eat it, especially horses. While neither of the writers has had an 

 opportunity of personally corroborating this statement, it is vouched for by many 

 reliable residents of the region. The narcotic effects of the plant, which are said to 

 appear soon after it has been eaten, are indicated by drowsiness or sleep on the part 

 of the affected animals, which continues often for 48 hours and sometimes results in 

 death. Animals which have been reared in these mountains never eat sleepy grass, 

 but those which are brought into the region will consume it because of its luxuriance 

 and freshness, unless restrained. Strangely enough, the dried grass does not have a 

 narcotic effect. The grass is abundant in other regions of the State, but nowhere 

 besides in this one range is it reputed to have narcotic properties. WTiere it is^not 

 eaten by stock it grows vigorously and spreads rapidly, especially when other plants 

 are killed by overstocking.
