whole premises have gone out of repair, and are fast falling to 
ruin. 
The water of the springs has no perceptible taste, and only a very 
faint smell of sulphur is perceived. No gas escapes from it, but a white 
incrustation covers the stones over which the water flows. 
Some of these waters were obtained, and since our return were put 
into the hands of Dr. C. T. Jackson, of Boston, who gives the following 
analysis: 
Specific gravity, 1*0043; thermometer 60° ; barometer 30*05 in. 
A quantity of the water, equal in bulk to three thousand grains of 
distilled water, on evaporation gave— 
Dry salts, 5*95 grains.

them to make another visit to so interesting a field of research. They 
found the lake so rough that they w r ere compelled to return, and 
remain until eight o’clock. This, however, gave our botanists another

On the shores a number of birds were feeding, including pelicans, with 
their huge bills, the diver, with its long arched neck, herons, gulls,
