Rh Picton reported 4•76" rain. It has not been possible to present this as an example, because one of the days was a Sunday when very few observations are recorded.

As a rule these north-east cyclones recurve at the coast line. Charts 22 and 23 show the weather conditions on March 10th and 11th, 1891.

On March 10th there was a sudden fall of pressure on the coast of Queensland, about latitude 24° (Chart 22), and an accession



of wind and sea which clearly heralded the coming storm. This was intensified on March 11th, (Chart 23) by a further fall of three-tenths of an inch, and three more isobars of the cyclone were marked on the coast south to south-east; gales prevailed in its neighbourhood with very heavy rains.

On March 12th, (Chart 24) the anticyclone had retreated to New Zealand, and the cyclone travelled to the south along the coast intensifying as it came. The barometer curve at Brisbane was exactly of the cyclone type and dropped to 29•5. In the southern part of Queensland and northern of New South Wales heavy southerly to easterly gales were experienced. On the 13th the storm had disappeared to the eastward.
