ROADS AND OTHER FACILITIES 
Perhaps few other activities have aided development in Polk 
County so much as the network of fine roads. In 1924 Polk County 
had approximately 346 miles of asphalt-surfaced roads. The value 
of hard-surfaced roads to this community may be better appreciated 
after an understanding of the soil characteristics, for with sand having 
a depth of 4 feet or more, teams or trucks would haul heavy loads on 
unsurfaced roads only with great difficulty. 
Polk County has many rapidly growing little cities yh every 
modern improvement. The location of these cities on the shores of 
lakes makes them attractive places to live. With 600 lakes in the 
county, it is possible for a great many people to find desirable home 
sites. The schools, churches, and clubs are a source of great pride 
to the citizens. 
SELECTION OF A GROVE SITE AND VARIETIES 
No attempt should be made to buy or plant a grove without a 
previous thorough study of the problems involved. Lacking this, 
the best substitute is probably the service of some one with experience 
in the district and the industry. All such matters as soil, topography, 
home site, roads, packing-house facilities, shipping facilities, by- 
product manufacturing plants, necessary capital, varieties of citrus 
fruit, bud wood, and root stock are important and the lack or failure 
of any one of these may have much to do with the success of the 
business venture. 
THE LAND 
In selecting a grove site in Polk County, the following points with 
respect to the land should be kept in mind: 
1. It should have good water and air drainage. 
2. The soil should have a good depth of Norfolk sandy loam or 
other desirable soil, which is underlain with clay and not hardpan. 
Two to four feet of sand is about the right depth.
