and in what capacity, at the bursting Of any
steam boiler. or collapsing OF q ffue ;or have
you been made acquainted, by othef means,
with the facts in any suck case? If 80, in
what case

side and that Of the lower guage cock
4. What was the weight per square inch

rusted or sticking in the aperture, Or was il
SO at the time
6. Had that part Of the boiler above the
water ever been heated to red heat, or sp.

found at the bottom Of the boiler? If 80,
what was it's thickness and composition?
B. In what part was the boiler rent, and
what was the appearance g. extent ofthercnt?
o. If the bursting happened to the boiler Of
a steamboat, was the boat under wsy, or at
