PLOTS OF MANGELS AND TURNIPS. 



y 



In conducting these experiments, the roots only have been taken from the land, 

 the tops have always been cut off and left on the ground to be ploughed under, so that 

 the plant food they have taken from the soil has been returned to it. One half of each 

 one-tenth acre plot in the series has been devoted to the growth of mangels, and the 

 other half to turnips, and these crops have been alternated from year to year. The
