<br />CAUSE OF FLOOD.' ,
<br />
<br />. The cause of, the flood WIlS a series' ofcloud-bl1r~' resulting fr~m
<br />heavy rain-bearing clouds striking against the mountains and being
<br />deflected upward.
<br />. . The daily w!iathermaps for the first week in June show that an
<br />area' of ,high pressure (exceeding ,30.5,incheS) appeared over. the

<br />.. When rain beglna to tall mora rapIdly than the 8011 can ab.orb It, the lIrat thIn'
