      Day 2: 29th January 2009
      The Birches have stopped flowing sap! This means that the theory of the sap
        in birches not travelling all the way down to the roots is more than likely true.
       This also means we haven’t  missed the Rising Day for the Birches which is
       good news.

       We measured out the amounts of sap from each tree:

       NAME:                      AMOUNT:                      COLOUR:
       Birch 1, Jug 1           247 ml                           Light Yellow                
       Birch 1, Jug 2           162 ml                           Orange
       Birch 2                      203 ml                          Light Yellow
       Birch 3                         3 ml                           Light Yellow

  
    
           Silver Birch Tree

      
                Birch Leaf.
     

       The sap flow in Birch 3 was much smaller, most of it not even making it down
       the pipe into the jug, but there was still some definite flow. Lack of flow could
       be because of Birch 3 being smaller than 1&2, we drilled almost to the top of
       the sap line in this particular tree, or because it is on peat soil, or some mixture
       of the three. The significant change in colour in Birch 1 Jug 2 is strange also.
       We wont draw any more conclusions about these things until after Rising Day.

       We will keep checking the jugs twice daily and give an update when something
       new happens.
