THE GEOLOGY OF NELSON. 
recently said at Auckland with regard to the quality and 
economical uses of this coal. The Motupipi coal is of the 
same geological age, and of the same description, as the Drury 
coal at Auckland. It is to be regretted that works commenced 
with so much judgment and regularity, and which might easily 
be continued, should be no longer carried on, in consequence 
of the high price of the fuel, and the difficulty ol putting it 
oil board the ship. To obviate the last difficulty, Mr. Burnet 
proposes a coal depot at the Tata Islands, where vessels could 
easily take it in. 
Tertiary Formation of Blind Bay. 
That the waters of Blind Bay at one time extended much 
further to the south, and covered a larger area, than they do 
now, is proved by the fact of a tertiary formation filling up 
the space between the eastern and western ranges from the 
lake country to the shores of the Waimea ; but for the most

This shaft was abandoned on account of the large quantity of water. 
Had this not taken place, it was intended to sink to a seam known to
