vation C was made, and in the same character of soil, but a 

 northern portion of this patch rose on a slope and continued 

 on higher ground to a straight line of fence, and had more 

 gravel in the sand. Upon this high ground and on the side 

 of the hill, facing nearly west, occurred the burrow laid bare 

 by excav^ation D. The northern entrance B was about thirty- 

 five and a half feet south of the fence, and the entrance A 

 about forty-two feet south of the fence. 



The northern entrance B of the burrow was distant thirteen 

 feet and seven inches from the southern one A. The under- 

 ground direction from the northern entrance is straight to b, 

 and the direction (from b) is north-east by north, and the dis- 

 tance seven feet, eleven inches. From b the runway extends 

 east by south-east to entrance A eight feet, two inches, making 

 the total length of the runway sixteen feet, one inch. The 

 runway descends from B to b, and at C is thirty-three and a 

 half inches and at b thirty-six inches below the surface. 

 From b to entrance A it gradually ascends, being thirty 

 inches below the surface. Average depth of entire runway 

 below surface, excepting near entrances, was about thirty-one 

 inches. 



West and south of entrance A, and touching the latter, lay 

 a very large heap of sand, evidently thrown out of the run- 

 way. This heap measured six feet, two inches in length and 

 three feet, two inches across, and was eight inches high. A 

 measurement of the cross diameters of the runway at the 

 point D (b) showed it to be nine inches wide by four and a 

 half inches high. This indicates that the animal lies quite 

 flat and in a comparatively compact position when passing 

 through the burrow. 



EXCAV.VTION K. 



Another burrow near the la.st. and in ground on substantially 

 the same level, is shown by excavation E. The entrance lay 

 twenty-two feet from the north fence already mentioned. It 

 was fifteen feet long and nine feet wide, while entrance C, 

 lying nearly due ea.st and located ten feet distant in a straight 

 line, was sixteen inches long and eight inches wide. 



The burrow ran south-east for twelve and three-quarter 

 inches, then east fifty-nine inches, next north-east for five feet
