     1        one gets a run off into the water supply, for instance,
     2        which raises nitrate levels.
     3
     4   Q.   One can get eutrophication if one puts too much fertilizer
     5        in the land.  We all know that, do we not; that is what you
     6        mean, is it not?
     7        A.  Not quite eutrophication.  That is just one example.
     8
     9   Q.   Too many phosphates and nitrates and you change the
    10        character of the fauna and flora in the river, do you not?
    11        A.  Yes, and you kill off fish and so on.
    12
    13   Q.   In certain circumstances you can get a degree of
    14        deoxygenation, can you not?
    15        A.  Yes, that is one reason and you get algae growth.
    16
    17   Q.   Yes, Canadian pond weed, for example?
    18        A.  I am not too -- I have heard of it.
    19
    20   Q.   Never mind.
    21
    22   MR. JUSTICE BELL:  We are getting a bit far away.
    23
    24   MR. RAMPTON:  You and I can swap learning about rivers for ever,
    25        I dare say?
    26        A.  I was not prepared to tell what a hinny.
    27
    28   Q.   You were not then seeking to suggest that the collection of
    29        pig slurry in an hermetically sealed container constituted
    30        an immediate threat of pollution?
    31        A.  Well, it depends where the hermetically sealed
    32        container is.  I mean, if it is taken out of that container
    33        and sprayed across the fields, which happens with a lot of
    34        slurry -- you see muck spreaders doing this -- then it
    35        causes a problem.  Of course, the text book answer to this
    36        is:  Look what has happened in Holland where you get a
    37        particularly severe problem because of the particular
    38        intensification.  So, we have the problem but to a lesser
    39        extent.
    40
    Q.   Can I move briefly now to Midland Meat Packers and plant B
    42        which, as a matter of fact, I think is Jarretts, both of
    43        which are visited by Dr. Gregory?  You will have noticed
    44        that he ----
    45        A.  Could you just wait a minute, please, because I have a
    46        problem here?  Now I am on this file which you lent me and
    47        it is Mr. Chambers.
    48
    49   Q.   That was Mr. Chambers.  He gave the evidence of general
    50        practices and day-to-day working at Midland Meat Packers. 
    51        Dr. Gregory visited that establishment.  He also visited 
    52        another one which in his report he described as "plant B", 
    53        yes?
    54        A.  Yes, I am sorry.  I just made a few notes but I cannot
    55        find them now.
    56
    57   MR. JUSTICE BELL:  Just take a moment.
    58        A.  Yes, I am sorry, I got into a bit of a muddle.  Yes,
    59        here we are.
