tural w^riters of the 1 7th century. Gerarde, however, says tliat 

 there is a trefoil of this kind which is sown in fields in the low 

 countries of Italy, &c. that cometh up ranker and higher than 

 that which groweth in meadows, and is an excellent food for 

 catde, both to fatten them and cause them to give great store of 

 milk. Gerarde, herball. p. 1018. edit. 1579. White clovern 

 generally sown in pastures to be fed on the land. The time and 

 mode of sowing is the same as that for red clover^ see Trifhlm 

 pratense. The nutritive products of white clover^ according to
