  a point far to leeward, having been blown along by the

  wind in the meantime.

  A shell dropped into the hollow in front of the target

  at B, will not appear immediately, but by the time the

  smoke rises to the level of T it will have thinned so that

  the target shows through it, giving it much the appearance

  of a burst over. This error can be avoided or detected

  by careful verification, for though a shell at the bottom

  of a hollow may be deceptive, there is not likely to be much

  doubt about one which strikes only a few feet down the

  side of the hollow

  Frequently a burst behind the target makes it show up

  NOTE
  

  With howitzers the burst on graze of the heavy shrapnel

  is usually easy to observe. In difficult cases "Lyddite

  Shell" which gives an enormous cloud of smoke is

  used for ranging

  Whenever the enemy's men are visible, close observation

  of their movements with the telescope gives the most

  reliable indication as to the effect of the fire
