1 For the first several months of your horse's jumping training, keep the jumps so small that he can go over them from a standstill. 2  If your horse questions a jump, never let him turn away and reapproach the fence. 3  If you allow this, you're teaching your horse how to say no.
(May 2012) True north (geodetic north) is the direction along the earth's surface towards the geographic North Pole. True geodetic north differs from magnetic north (the direction a compass points toward the magnetic north pole), and from grid north (the direction northwards along the grid lines of a map projection).
Since the North and South Magnetic Poles are not located exactly on the Earth's North and South Poles, respectively, and due to other irregularities in the Earth's magnetic field, true north differs from magnetic north in most locations.ne consequence of this is that magnetic compasses do not point to true north in most places. Magnetic declination is the angle between the local magnetic field and true north, and can be represented on maps by isogonic lines, which connect locations that have equal magnetic declination.
