             THE SECRETS OF THE BOG.   81
    old Gombeen thought  he  had  it  that  time  !  "  and
    Dick laughed.
     " How did you manage the bog ?
     " That  is the only  difficult part  ; we have poles on
    opposite  sides  of  the bog with  lines between  them.
    The magnet is fixed, suspended from a free wheel, and I
    let  it down to the centre from each  side in turn.  If
    there were any attraction I should feel  it by the thread
    attached to the magnet which I hold in my hand."
     "It  is something like fishing ?
     " Exactly."
     Murdoch now returned and told us that he was ready,
    so we all went to work.  I kept with Sutherland at the
   far side of the bog, Murdoch remaining on the near side.
   We planted or rather placed a short stake in the solid
   ground,  as  close  as we could  get  it  to the bog, and
   steadied  it with a guy from the top  ; the latter I held,
   whilst Murdoch, on the other  side,  fulfilled a similar
   function. A thin wire connected the two stakes  ; on this
    Sutherland now fixed the wheel, from which the magnet
    depended.  On each  side we  deflected the stake until
   the magnet almost touched the surface of the bog.  After
   a few minutes' practice I got accustomed to the work,
    and acquired sufficient dexterity to be able to allow the
    magnet to run freely.  Inch by inch we went over the
    surface of the  bog, moving  slightly to the south-west
    each time we shifted, following the edges  of the  bog.
    Every  little while Dick had to change sides,  so as  to
    cover the whole extent of the bog, and when he came
