The inquest was resumed at O'Clock p. m.
Elbridge Joslyn testified he had been founder 50

half an hour to test six eight pillars the Atlantic
pillars were seven inches in danneter in the lower
story and thicker than la the Pemberton; each pillar
in the Atlantic weighed 800 pounds; in testing pillars
we struck them hard enough to break defective one

him they were making pillars too cheap. They used

John c. Hoadley, Superintendent of the Lawrence
Machine Shop for seven years testified that the defect
in the pillars the ecccntrcty Of the case All hollow
columns are liable to this, but they should not be
nitric as these. When pillars are cast thicker on
one side the thin aide cools quickest and the unequal
tension renders them liable TO warp. We test by in-
spcon and hammeting. difference of half an inch
could be detected. Have three pillars at the
ins which, if properly inspected, should have been
rejected. Witness was struck with the lack Of stabili

one pillar broke it seemed that the whole must go
down. The jar Of machinery would act like repeated
blows.
