The scale
having previously been properly graduated, the metacentric height for
the draught and state of loading can be at once read off in inches,
while as a check the water can be transferred from the one test tank to
the other, and the metacentric height read off as before, but on the
opposite side of the zero pointer. At the same time the angle of heel is
shown on a second graduated scale, E. Having obtained the metacentric
height, reference to a diagram will at once show the whole range of
stability; and this being ascertained at each loading, the stowage of
the cargo can be so adjusted as to avoid excessive stiffness in the one
hand and dangerous tenderness on the other. It will thus be seen that
Mr. Taylor's invention promises to be of great practical value both in
the hands of the ship-builder and ship-owner, who have now an instrument
placed before them, by the proper use of which all danger from
unskillful loading can be entirely avoided.--_The Engineer_.
