POPULAR SCIENCE REVIEW. 
Immediately to the left of the Pink Terrace is a large 
solfatara, presenting in opposite extreme the most extraordinary 
features. Literally a lake burning with fire and brimstone, it 
is awfully suggestive of Tartarus, and although its repulsive 
character is attractive we must not linger in our description. 
On the western shore of Eotomahana there are five or six 
other basins of boiling water of lesser magnitude. The waters 
of the lake vary in temperature, but it is saline in all parts 
except the north-west corner, and here as our canoe is pushed in 
among the sedges the Maori boy dips up a supply of cool fresh 
water, sparkling and clear. 
The return journey by canoe takes us through the narrow 
rapids of the Karaka creek, where hissing steam-jets and mud 
holes line the banks. At Tarawera we re-embark, and stimulating 
our Maori boatmen with promises of good cheer when we reach 
the hotel, we make rapid progress to Wairoa. The return 
journey will be made via Ohinemutu, and through the “ eighteen 
miles bush ” by good but irregular coach road, forty miles to 
Tauranga, a beautiful harbour on the Bay of Plenty.

All but soda are monosilicates; the little excess of silica, 7*66, is included 
in the soda silicate.
