it is scarcely perceptible until bro'i^ht up by top-li which prob- 



ably has given rise to the very general opinion that it is indigenous to 

 some soils. The central root penetrates to a considerable depth, and the 

 plant is thereby enabled to resist the effects of drought, particularly on 



iy soils. 



The branches which trail on the surface send fibrous roots from their 



joints down to the ground, and hence this species of clover maintains it- 



in land of opposite qualities, for if the surface be too dry to afford 



nourishment to the foliage, it is preserved by the roots. It is not, how- 



nutritive as the common annual red clover, nor does it form a 



good pasture when sown by itself, for it has been found injurious to 



but, combined with other grasses, it is a valuable plant. It ha> 



1 there is no better test of good land than its running spontane- 



ously to white clover. Its analysis is a good one. 



ALSYKE OR PERENNIAL HYBRID CLOVER (Trifolium hybridum). 



AKyke or Perennial Hybrid Clover, which takes its name from the 

 Alsyke district, near Stockholm, was first introduced into Sweden. 



Within the last century vast improvements in agriculture have enabled 

 this valuable clover to be brought to great perfection, and it is now held 

 in high estimation by the Swedish farmers, and extensively cultivated by 

 the leading agriculturists in Great Britain and America. 



Y HI. LOW CLOVER, HOP TREFOIL, OR SHAMROCK CLOVER (Trifoll 



procumbens). 



Shamrock clover grows naturally on dry, gravelly places, and has 

 been recommended for growing on such soils as are incapable of support- 

 bhe more valuable grasses and clovers; but, from the >mall Itulk of
