CULTIVATION AND IRRIGATION 73 



On moist soil, such as peat land, where level cultivation 

 is practiced, the best method of planting is to make deep 

 furrows, then, after planting, the soil is harrowed length- 

 wise, covering the pieces lightly. After two weeks it is 

 harrowed again, this time covering them more, but not com- 

 pletely filling the furrows. Afterward, in the first cultiva- 

 tion, the loose soil is rolled up to the rows, making the soil 

 levelj then a small harrow-tooth cultivator is used, one that 

 will keep the surface level. This is called level cultivation, 

 and is practiced on soils containing natural moisture. 



In conclusion of this chapter on "Cultivation and Irri- 

 gation," I would emphasize these points : 



1st. Always cultivate thoroughly. 



2nd. Allow the potatoes to mature in practically dry 

 soil. 



3rd. Never allow the soil to become too wet. Potatoes 

 grown in such soil are of a poor quality, more liable to 

 disease, and the yield is less. 



4th. The number of irrigations depends upon the cli- 

 matic and soil conditions. One may be sufficient, but in 

 some instances five or six, or even more, may be needed. 



5th. Cultivate the soil well before planting and less 

 will be needed after planting. 



6th. Never allow the potatoes to become too dry. If 

 irrigated after they become too dry a new growth starts and 

 prongy tubers are the natural results.
