temperature of 8 deg. Cent, requires a long time, and the cold
weather is over before it is accomplished. In the shallower
portions, the surface of the water may reach the temperature
of congelation, but the agitations due to the action of
strong winds soon breaks up the thin pellicle of ice, which is
quickly melted by the heat generated by the mechanical action
of the waves. Nevertheless, in shallow and detached portions
of the Lake, which are sheltered from the action of winds and
waves--as in Emerald Bay--ice several inches in thickness is
sometimes formed.

(4.) _Why Bodies of the Drowned do not Rise_. A number of
persons have been drowned in Lake Tahoe--some fourteen
between 1860 and 1874--and it is the uniform testimony of the
residents, that in no case, where the accident occurred in
deep water, were the bodies ever recovered. This striking fact
has caused wonder-seekers to propound the most extraordinary
theories to account for it. Thus one of them says, "The water
of the Lake is purity itself, but on account of the highly
rarified state of the air it is not very buoyant, and swimmers
find some little fatigue; or, in other words, they are
compelled to keep swimming all the time they are in the water;
and objects which float easily in other water sink here like
lead." Again he says, "Not a thing ever floats on the surface
of this Lake, save and except the boats which ply upon it."

It is scarcely necessary to remark that it is impossible that
the diminution of atmospheric pressure, due to an elevation
of 6250 feet (1905 meters) above the sea-level, could sensibly
affect the density of the water. In fact, the coefficient of
compressibility of this liquid is so small that the withdrawal
of the above indicated amount of pressure (about one-fifth
of an atmosphere) would not lower its density more than one
hundred-thousandth part! The truth is, that the specific
gravity is not lower than that of any other fresh water of
equal purity and corresponding temperature. It is not less
buoyant nor more difficult to swim in than any other fresh
water; and consequently the fact that the bodies of the
drowned
