TROTTING TRACKS.

While speaking of fences, be sure and have a hub- 

 beard on the pole one, and have the one that encloses 

 the grounds high enough to defeat the efforts of fence 

 scalers — and it need be high, for they are climbers from 

 the headwaters of Climber's Creek. A couple of barbed 

 wires strung on top of the fence, about eight or ten 

 inches apart, is a cheap thing, and not a cheerful pros- 

 pect to these vermin. 



The turns on a mile track should be "thrown up"

would, at its highest point, be four feet higher at the 

 outside than at the pole. On a half-mile track the turns 

 should be "thrown up" one foot and three inches in every 

 ten feet of width, or five feet on a forty-foot turn. It 

 is obvious that this rise cannot be abruptly made at the 

 commencement of the turn, and I would therefore recom- 

 mend that it be commenced far enough back from that 

 point so that one-half of the total rise would be gained at 

 the commencement of the turn. For convenience, it would 

 be well to lay off stations of forty-four feet each, com- 

 mencing four stations back from the point of curve and 

 gradually raising one-half foot in each station, so that
