  At my request, Gilbert to-day took the
dimensions of the form of the Cottontail
Rabbit (Lepus floridamus mallurus) that
was found recently back of the Barrett 
House. I compile the following: -
  The entrance hole is on the surface of
the ground and slightly inclined, being nearly
circular in outline with a diameter of five
(5) inches. Sides of the hole nearly perpen-
dicular except on the highest side of the
entrance where there is an excavation
running in three (3) inches. The depth of
the hole at the highest edge of the en-
trance is four and one half (4 1/2) inches. The
depth half way in the excavation is three
(3) inches. The sod covering the hole is
half an inch thick at the edge of the en-
trance, but thickens to three inches to-
wards the end of the hole.
