     2   Q.   With the old baths, the one-and-a-half-metre baths that
     3        used to be 13 birds in them, how long would they remain in
     4        there?
     5        A.  I do not know.  I think it was a little bit longer
     6        because it was a longer bath.
     7
     8   Q.   But obviously that would be something that was dependent on
     9        the speed that the line was moving?
    10        A.  Yes, it would do.
    11
    12   Q.   When was Dr. Perry at Sun Valley?
    13        A.  He was there when I came to the company, and I think he
    14        left in probably about 1984.
    15
    16   Q.   You said that you used to use AC current.  Dr. Gregory said
    17        he thought that you probably changed from 25 milliamps to
    18        16 milliamps at the same time you switched over from a
    19        13-bird bath to an eight-bird bath.  Would that be right?
    20        A.  It might be.  I really do not know.
    21
    22   Q.   Does Sun Valley have an easily visible ammeter fitted to
    23        the stunners to make it possible to check the current?
    24        A.  Yes, it does.
    25
    26   Q.   How long has it had that?
    27        A.  Really since the new installation was put in two years
    28        ago.
    29
    30   Q.   So prior to that there was no ----
    31        A.  It could be read before but it had to be done by a
    32        qualified electrician because it required access to a
    33        particular area that was relatively inaccessible.
    34
    35   Q.   So, at that time, the water bath area had restricted
    36        access?
    37        A.  The water bath area itself did not have restricted
    38        access; only the control box.
    39
    40   Q.   How often would that have been checked?
    41        A.  Well, the checking was done more on the reaction and
    42        behaviour of the birds going into the stunning bath rather
    43        than reading dials on pieces of equipment.
    44
    45   Q.   So basically they would not really use the dials apart from
    46        on rare occasions?
    47        A.  The dials were not part of daily use because it was
    48        felt to be more valuable just to observe the operation
    49        actually in practice.
    50 
    51   Q.   It is actually a recommendation in the 1991 MAFF code of 
    52        practice to have a visible ammeter, is it not? 
    53        A.  Yes.
    54
    55   Q.   The Simmons Engineering documents we looked at yesterday
    56        said if you remove a bird from the shackle after using
    57        their prestunner it will revive completely within two
    58        minutes or less.  Have you tested to see whether that
    59        happens at Sun Valley?
    60        A.  No.  We are not allowed to do that.
