Bounding the University property on the north is the 

 Newberry Road. The Ocala Road bounds it on the east and 

 south. Following the Ocala Road northward until we strike 

 a branch of Hogtown Creek we find magnolia hammock. This 

 branch of Hogtown Creek runs along in a winding course 

 through hammock until it joins the east branch of Hogtown 

 Creek. Hogtown Creek crosses the Newberry Road about 

 a mile and a half from the University grounds. (Fig. G). 



Every year during the rainy season Hogtown Creek over- 

 flows, flooding the surrounding country and making an alluvial 

 floodplain. Growth along its banks is at most places very 

 rank. This is a favorite place for Geometridae. 



Just beyond the College Inn, on the right of the Newberry 

 Road, is typical piney woods, which extends to the western 

 boundary of the University property. 



TEMPERATURE AND CLIMATE. 



The following table shows the average temperature and 

 rainfall at Gainesville, down to 1908. 



The most salient features of the climate are the mild dry 

 winters and wet summers. The rainy season begins in June 

 and lasts until September. The copious summer rains seem to 

 be largely responsible for the prevalence of poor sandy soils 

 and evergreen trees in Florida, for the rain tends to leach out 

 the clay, lime, potash, etc., leaving the plain sand. Ever- 

 greens (Harper '14) seem to be especially characteristic of soils 

 poor in clay and potash. 



There is a killing frost nearly every winter, the average date 

 being December 11th, and occasionally a freeze. A tem- 

 perature as low as 26° is common. 



As a whole this is not a region of high winds. During cold 

 weather and strong winds, insects find a haven of safety in 

 the deep recesses of the hammocks.
