seeming relish, taking a bite of the clover and then another 

 of the poa aqnaiica, alternately, till the whole of it was con- 

 sumed. It does not grow freely from seed, except vvhen 

 sown in mud. The best manner of propagating it, according 

 to my experience, is by planting the roots, which, from their 

 creeping nature, soon increase the number of plants. The 

 best season for sowing the seeds is in the autumn, as soon 

 as they are ripe. The roots may be planted in the autumn, 

 or spring, with equal success. The Rev. Bartholomew Dacre, 

 of Mosely, has made several experur.ents on this grass ; and 

 the results prove, that it may be cultivated on more elevated 

 situations than has been supposed, and that propagating it 

 by planting the roots is the best mode. 



Flowers about the second and third weeks of July, and 

 the seed is ripe about the second week of August. 



ERIOPHORUM angustifoUiim. Long-leaved Cotton-grass. 



Sjjecijic character: Culms almost three-cornered; leaves 

 channelled, three-sided ; fruit-stalks smooth. 



Obs. — There are three species of cotton-grass, which 

 greatly resemble each other : the e. trujuetrum, e. aiigus- 

 tifolium, and e. pohjstachion. The e. angustifolium (the 

 species now under consideration), differs from the 

 triquetnmi in having a thicker and more succulent 

 culm; the leaves longer and broader, with only one 

 nerve of a reddish colour ; and the fruit-stalks are 

 smooth. It is distinguished from the poli/stachion by 

 its creeping roots ; leaves twice the length ; involucre 

 and sheaths smooth, spikelets smaller; fruit-stalks 

 shorter ; and the woolly hairs everywhere longer. 



Native of Britain. Root perennial. 



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

 a bog soil is 8,167 lbs. per acre. 



On bogs and moors where this grass abounds, cattle crop 

 the leaves in the spring ; but as soon as the finer kinds of 

 grasses afford them a bite, they neglect it. There are 

 many grasses of superior value, that succeed equally well on 

 this kind of soil. When such lands are capable of being
