built on the tops of the islands and in that case they had both 

 shallow runways, like trenches, leading from the nests to the open 

 water, and also holes leading straight down to the bottom of the 

 island, from the usual entrances found in the floating nests. I 

 set a number of traps in these runways but caught only one rat 

 there, so they can be used but very little. A day or so before I 

 left Gainesville, I went after rabbits around the western end of 

 Payne's prairie and while going through a cane-brake found a 

 dead Neofiber lying in the water with a wound on its head, but 

 though I searched everywhere in the vicinity for .a nest or run- 

 way could find none. This was some distance from the open 

 water. It is my opinion Neofiber is abundant on Payne's prairie, 

 for it extends for miles, but is impenetrable on account of the 

 matted growth of weeds and grass, interspersed with big open 

 stretches of water, the abode of myriads of snakes. However, 

 I think the use of a canvas canoe would solve the difficulty, and 

 the collector who goes there with one will no doubt reap a 

 harvest. One of the rats being but slightly injured was taken to 

 the city where I attempted to photograph it alive, but with poor 

 results, as it fought like a fury, biting at everything in reach."

Three examples: 2 Apex, North Carolina ; i Catawba, South 

 Carolina. 



Of this species Mr. Surber states that "two pine voles were 

 secured in the pine woods at Apex, North Carolina, where they 

 were undoubtedly common, and another was taken in a cotton 

 field at Catawba, South Carolina. I am positive they are quite 

 common at Calhoun Falls, but all my efforts to get any failed, 

 and no others were secured on the entire trip."

One example taken at Rocky Ford, Georgia, "among the 

 sand hills, between the railroad track and the Ogeechee River. 

 Although I searched the country for miles, no others were 

 found."
