 Experiments. — At the time of flowering, the produce from 



a rich sandy loam is 21,780 lbs. per acre. 

 The produce of latter-math is 9,528 lbs. per acre. 

 The crops of this grass, at the time of flowering, and at 

 the time the seed is ripe, are equal in point of quantity and 

 nutrient quality, a circumstance which has not occurred in 

 any other grass mentioned in this series of experiments. 

 The nutritive matter contained in the latter-math is hkewise 

 greater than in most other grasses. The root-leaves are pro- 

 duced on a shoot, and stand in two rov^^s after the manner of 

 a fan. This shoot, which is formed by the union of the base 

 of the leaves, is very succulent, and contains a greater pro- 

 portion of nutritive matter than the leaves, which accounts 

 for the superiority of the latter-math in nutritive matter. 

 This grass is remarkably hardy. In February 17, 1814, after 

 the severe winter preceding, this species of ^oa was perfectly 

 green and succulent, while not one species of grass, out of 

 nearly three hundred different species that grew around it, 

 remained in a healthy state, but were all inferior, and more 

 or less injured by the severity of the weather. In the fol- 

 lowing season, the produce rather exceeded the above, 

 though it had been mown the preceding season, and no 

 manure had been applied. It is a native of North America, 

 where the winters are longer or more severe, and the summers 

 warmer than in this climate ; and the plants, natives of 

 Siberia, exhibit a similar habit, for the severer the winter, 

 the greater is their produce ; and the milder the winter, their 

 produce is comparatively less. The long-rooted clover is 

 one of this class : after a severe winter the produce is very 

 great, but after a mild winter the produce is considerably 

 inferior*. 



The nerved meadow-grass affects most soils, but not such 

 as are tenacious. The seed does not vegetate so readily as 



* This is the case with the greater ])art of the grasses ; the more 

 they grow in winter, the less they grow in summer. — Ed.
