64 THE FERTILITY OF THE SOIL [CH. 



A farther improvement was soon to take place in 

 soil fertility. A great advantage of the enclosure 

 over the common fields was that crops could now 

 be grown in autumn and winter ; obviously this 

 course was impossible when the village cattle strayed 

 at will over the land from Lammastide to Candlemas. 

 Consequently about the middle of the seventeenth

 methods of tillage. The old implements were very

 and payne to the oxen, to goo to harowe; for they 

 were better to goo to the plowe two dayes, thanne to 

 harowe one daye. It is an old saying, 'The oxe is
