HOW TO GROW GOOD CLOVER. 117 



if so the position of the three may be expressed 

 as follows : — 



Trifolium pratense. Trifolium medium. 



Trifolium pratense perenne. 



At all events, if this plant was ever distinct in 

 cultivation, it has merged into broad clover forms ; so 

 that, if we are to possess it as a separate plant, it 

 must again be grown from wild seed, and then, if it 

 is to be kept pure, it must not be cultivated on clays 

 or limestone, or, if our view be correct, it will soon 

 lose its true distinctive characters. 



3. Trifolium incarnatum — Annual Carnation or 

 Crimson Clover — is a large species with oblong heads 

 of flowers of a fine carnation colour, hence its common 

 name of " Carnation Clover." It is a native of 

 Southern Europe, and is said to have been found wild 

 at the Lizard, in Cornwall. As a cultivated plant, it 

 has not long been introduced into England, where it 

 has been much grown in the southern counties, as 

 there it can be sown soon enough on the wheat 

 stubbles with only just a simple harro wing-in, when 

 it has time to make a plant sufficiently strong to 

 resist winter ; this soon makes growth in the spring, 

 giving an early feed, or it may be mown ; in either 

 case it is off the land sufficiently early to allow of a 

 late sowing of turnips : so that, where the climate will 

 allow of it, we may snatch an intermediate crop by 

 means of the carnation clover. It yields a large 

 crop, but its feeding qualities, according to Dr. 

 Voelcker, are somewhat inferior to those of the 

 broad-leaved clover. It should be noted that varieties 

 having white flowers are in the market, and of both
