    To convert between Grid north and magnetic north on a map, use: East is
    least, West is best.

    If the magnetic variation is, say, 3 degrees west, add 3 onto the grid
    bearing to obtain a magnetic bearing. And vice versa.

    "Come on, see daring men play polo." (Cambrian, Ordovician, Silurian,
    Devonian, Mississippian, Pennsylvanian, Permian).  "Phooey! Even old men
    play polo, right?" (Palaeocene, Eocene, Oligocene, Miocene, Pliocene,
    Pleistocene, and Recent).

     As many eras have the same first letter, this can be confusing (originally
    pensylvanian and permian were transposed in this list).

    A better mnemonic avoids this problem (it incorporates the first *three*
    letters of each name) is "CAMpus ORDered SILicon DEVices, MISsed PENcil
    PERmits," which gives a nice leg up on memorizing the mnemonic.

     The Open University Geological Society uses:

    (eras: Precambrian,Cambrian, Ordovician, Silurian, Devonian, carboniferous
     Permian, Triassic, Jurassic, Cretaceous) (cenozoic: Paleocene, Eocene,
    Oligocene, Miocene, Pliocene, Pleistocene)

     To remember the names of subdivisions of the paleozoic era in French:

    "CAMbronne, OR DOnc, S'IL eût été DEVOt, n'eût point CARBONisé son PERe"

    = Cambrien , Ordovicien, Silurien, Dévonien, Carbonifère, Permien

    (we don't speak very often of the Mississippian & Pennsylvanian this side
    of the Atlantic.  They are grouped under the heading "carboniferous")

    Cambronne was the hero of Waterloo much as Mc Auliffe is Bastogne. His
    answer was a four-letter word, which is 5-lettered in french.

    The sentence may be translated as :

    Cambronne, by the way, were he devout, wouldn't have burnt his father to
    death.

     To avoid confusing stalactites with stalagmites:

     Stalactites: They hang on tite
    	    : stalactites hang onto the ceiling.

     There's no c in stalagmite.
      Stalagmites: They aren't stalactites.

     To avoid confusing stalactites with stalagmites: As mites go up, tites
    come down.

     The easiest way to remember Stalagtite/ mite is: Stalagmites mite hang,
    but they don't.

     StalacTITEs hold TIGHT to the roof, and stalagMITEs MIGHT one day join up
