quired for each poiincL of growth, the acre of rape 

 would be credited with producing- alone 413 pounds of 

 growth, worth, at 4 cemts per pound, |16.52. 



In addition, the rape which had been grazed made a 

 second growth which was ready for pasturing witliin 

 a month after the removal of the shoats, but which was 

 ruined by the Haxlequin cabbage bugs, or "calico backs," 

 before it could be utilized. 



The soil in which this patch of rape grew would be 

 classed as sandy bottom land of medium grade. 



Let us turn aside here from the history of this litter 

 of pigs, which we may call litter M, to describe some 

 tests of rape made in 1900 and 1901. 



Rape as Winter Pasturage for Pigs. 



Dwarf Essex Rape sown in drills on sandy upland, 

 October 13, 1900, was ready for pasturage January 6, 

 1901, when four pigs from litter O, weaned three weeks 

 before, were confined on it with hurdles which were 

 moved about once a week. The first growth of rape af- 

 forded pasturage until March 28. The second growth, 

 on land previously grazed over, affordted pasturage from 

 March 28 to April 18. 



Throughout the whole period that the pigs were on 

 rape they received also about a half ration of com 

 meal. 



Less rapid and more expensive gains were made in 

 March, when the plants had become tough aind ready 

 to seed, than during January and February. The most 

 rapid and economical growth was made during the brief 

 period while the succulent second growth was being con- 

 sumed.
