Columbus and particularly southward are hundreds of acres 

 devoted to intensive gardening. This is partly a response to 

 the call of the market, but the specific location of many of the 

 gardens is determined by the fertile, alluvial, deposits of second 

 bottoms south and west of the city (Fig. 7). Here and north- 

 west of Columbus are the two most favored gardening sections. 

 North and east of town this specialized phase of agriculture 

 does not occur, although all conditions but soil are probably 

 as suitable, as in the two sections used.

Windmills. — Over most of the western half of the area the 

 drift is deep and wells range from 50 to 150 feet in depth. 

 In response to this combination, himdreds of farmers have 

 erected windmills to pump the water. Winds usually move 

 over this level country with force enough to do the pumping. 

 Occasionally the deep well seems to necessitate the installation 

 of a gasoline engine, because the wind is scarcely able to do 

 the pumping. 



In a strip four to eight miles wide along the eastern part 

 of the area, springs from the sandstone are so common that 

 wells are rare; and wells, when needed, are so shallow that 

 windmills are still less common. The spring-house, however, 

 and the roadside watering trough are constant reminders to 

 the traveler of the different conditions. Springs also occur 

 in the gravel streaks of the glacial drift (Fig. 8).
