6 HISTORY OF BOTANY. 



book treats of ploughing, and preparing the ground; the 

 second of sowing and planting ; the third of the manage- 

 ment of cattle ; and the fourth gives an account of bees, and 

 the manner of keeping them. Macer, a poet, who died 

 B.C. 16, was much admired for his genius and learning, and 

 the elegance of his verse ; he wrote a poem on Plants. He 

 was intimate with Ovid, who mentions him, but all his 

 works are lost. Columella flourished about the middle of 

 the first century, and wrote a work on husbandry.
