adaptability. For instance, though it were possible 

 to produce a larger crop of artichokes in the soils 

 around Winnipeg than in those around Kansas City, 

 it would not follow that it would be more profitable 

 to grow artichokes as forage for swine in the former 

 soils than in the latter. The climate of Winnipeg 

 would lock the artichokes in the ground for five to 

 six months in the year, while the climate of Kansas 

 City would not so lock them for more than a few 

 weeks. But for a crop to be dug and stored for 

 winter, the former soils might be more suitable than 

 the latter. Highest adaptation, therefore, is to be 

 sought for in soils that will grow maximum crops, 

 and in a climate where they may be harvested by 

 swine during a large portion of the season which 

 follows the maturing of the crop. And it will prob- 

 ably be found in the alluvial lands of the Mississippi 

 and its tributaries, but not very near the sources of 

 these streams. 



Place in the Rotation. — Artichokes may come 

 after any kind of a crop, but since they should be 

 cultivated much the same as corn, they should natu- 

 rally be given the place of a cleaning crop. How- 

 ever, because of the difficulty that is frequently 

 found in ridding the land of artichokes, they should 

 always be followed by some kind of cultivated crop, 

 as corn, for instance. But a crop that could be 

 planted later, as rape, would be even better, as a 

 longer period would then be given for cleaning the 

 land before sowing the crop which follows the 

 artichokes. 



When artichokes are grown as swine forage, 

 however, it will frequently be found advantageous 

 to grow them during successive seasons on the same
