By analysing the table for March of the present year and that for April as far as it 

 has gone, and comparing the results with those of the corresponding periods in former- 

 years, the increasing di-yness of the seasons in Tasmania will be brought prominently 

 under notice. To counteract this deficiency of moisture, irrigation would of course 

 be the remedy, and fortunately our lakes and rivers afford every facility for caiTying 

 this out to any extent that might be required. If this, however, were found from any 

 cause to be impracticable, it might be well to consider if planting trees on a large scale, 

 as practised elsewhere, should not be now urged upon the attention of the pubUc.
