Construction of New Home of

Ing Difficult.

The science of building and the exact
science Of research work on terrestrial
magnetism are running a close race
for supremacy just now in the erection
of the $500 building which will be
occupied by the Carnegie Institution.

Chase drive. The builder and the
more precise scientist are both occupy
ing themselves with problems which
are difficult. the latter with delicate
Instruments that measure the vbra-
ton in the drop of a hair. But the
problems OF the builder are almost as
difficult. He must erect d building for
the scientists, which is briefly, con-
uacted for, when he guarantees to
erect a building with ''vibratioTiess
walls"
