Referring to this exhibit Mr. Smythe said in part: We had trouble with staybolts breaking from the start; andthe engine has been out about forty days since we put in the I believe the result of this test was that the first one whichwas within %-in. of the inside sheet, showed dry steam, thesecond wet steam, and the third water. This goes to show thatthe water boils away from the side sheets and I believe ourwater spaces are too narrow. In order to try to o
