'By comparison with distilled water,' says the same, 'the specific
gravity of the filtered river water we found to be 1.823; pint of such
water at 60 deg. weighs 7,297.40.' Engineer Forehay says the sediment is 1
to 1,800 by weight, or 1 in 3,000 by volume.

Professor Riddell also comes to the following conclusions, after an
analytic investigation of the sediment. He took one hundred grains from
the river margin, dried it at 212 deg. Fahrenheit, before weighing, and
found it to contain:

_Grains._

Silica, 74.15
Alumina, 9.14
Oxide of iron, 4.56
Lime, 2.08
