The drought of the past months still continues generally, a few stations only 

 have had useful rain, and the effects of the continued dry weather are most serious ; 

 cattle and sheep are said to be dying in immense numbers, and fears are entertained 

 that no grass can grow before the frosts, even if rain comes at once. At Sydney 

 the total rainfall for the month was only 0-419 inch, or less than tliat for any March 

 during the last 36 years, or the whole period on record. Evaporation has also been 

 very great, and the temperature 2-9 above the average.
