He was running at full speed when suddenly a foreleg found a deep badger hole; over he went of course, head over heels, and it is a miracle it did not break his leg off.

These badger holes, especially abandoned ones, go right down to a great depth, and the grass grows over them so that they are hardly visible.

Dog holes always have a surrounding pile of earth carefully patted firm and trod on, no doubt to prevent entrance of rain flood-water; thus they are nearly always noticeable.

Dog towns are sometimes of great extent, one in my pasture being two miles long and about a mile wide.

They are generally far from water, many miles indeed, often on the highest and driest parts of the plain and where the depth to water may be 500 feet or more.
