The eruption lasted some time, and was tolerably equable; only sometimes the column of water sank a little, to rise to its former height with renewed force.

After forty minutes it fell quite down into the basin again.

The stones we threw in, it rejected at once, or in a few seconds, shivered into pieces, to a height of about 12 to 15 feet.

Its bulk must have been 1 to 1.5 feet in diameter.

My guide assured me that this spring generally plays only twice, rarely thrice, in twenty-four hours, and not, as I have seen it stated, every six minutes.
