 sections, it must be remembered that Greeley 

 is one of the best known districts in the potato 

 world. 



"The soils in their natural state were not com- 

 parable to some of the mountain plateaus and 

 gulches, where grow the wild potatoes, in their 

 adaptability to potato growing. Alfalfa growing 

 and storage of water were necessary before potatoes 

 could be produced to the amount of 10,000 car- 

 loads and upward per year. 



"There were no popple washes, leaf mould from 

 mountain slopes or accumulation of dead grasses 

 on the plains to furnish stored food for the crop. 

 Cactus of short growth as a rule indicated those

 enduring base for the welfare of the potato. 



"The soil, so rich in mineral elements, was de- 

 ficient in humus, and it was not until alfalfa had 

 been grown some years that any tonnage was pro- 

 duced except here and there. The breaking up of 

 alfalfa at first gave an excess of humus in that it 

 forced vine and early growth; the tubers set on and 

 matured during the excessive heat of summer.
