J. D. Dana — Explosive Eruptions. 



105 



detonations began. Scoria and volcanic ashes or sand were 

 thrown to a great height, that drifted with the wind and 

 covered the country thickly and far away with ashes, making 

 darkness, over a breadth of several miles, all the way to the sea 

 in the Bay of Plenty. The height as seen from Auckland, 130 



miles distant, according to a measurement by Mr. Vickermann 

 of the Survey Department of New Zealand, was 44,700 feet. 

 The eruption was ended and the clouds of dust gone in six 

 hours. The work was done so quickly and fiercely that no 

 cinder cones were made by deposits about the place of chief 

 discharge. No outflow of lavas took place.
