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).
Meridian convergence. True north, magnetic north and grid north. Imagine as if you were somewhere on Earth (easy to imagine I guess), and you have one world map on one hand and a compass on the other. GRID NORTH: the map you are holding has probably some horizontal and vertical lines. The direction of every vertical line indicates the grid north.
