DIR. j. F.. TaImage Tells Just What This
Delic..tely Adjusted Affair is and
What II Can DO.

Salt Lake now has the distinction
of having a seismograph. There are
about five in the United States and this
city has the NOSE perfect. thereby hav-
ing two distinctions. Should there be
an earthquake ia any part of the world
Salt Lake win know about 1t before the
wires begin to bring in the first notice.

instructor of mechanics at the Univer-

installing the machinery. Each piece
had to be tested until it worked perfect

needle moves from side TO side. These
side linsS can be measured and mathe-
matieal deductions show the direction
and extent of the tremors. There is n
big difference between the marks made
during an earthquake and those made
during less violent disturbances
you notice this point striking the
paper regularly. This Is a time re-
eorder, the point makes a mark at the
slde of the straight line at every Sec
ond, minute or whenever desired. One
OF these time marks is marked to
show the time and then It Is easy TO
figure out the time and duration OF any
disturbance. The time recorder is con-
nccted with a clock In my workFoofn.
