As long as the water only filled the inner basin it boiled violently; but the higher it rose in the outer one, the less it boiled, and nearly ceased when the basin was filled: it only threw little bubbles here and there.
After a lapse of two hours--it was just noon--the basin was filled nearly to the brim; and while I stood beside it the water began again to bubble violently, and to emit the hollow sounds.

I had scarcely time to retreat, for the pillars of water rose immediately.

This time they spouted during the noise, and were more bulky than those of the first explosion, which might proceed from their not rising so high, and therefore remaining more compact.

Their height may have been from forty to fifty feet.

The basins this time remained nearly as full after the eruption as before.
I had now seen two eruptions of the Geyser, and felt amply compensated for my persevering patience and watchfulness.
