While these experiments were made with cold flues,it must be remembered that, at higher temperatures, the limit 168 THE AMERICAN ENGINEER [April, 1895. brick been put in with mason work, there would simply havebeen a collapsing without a rent, and no steam would have es-caped, nor would the accident have partaken ol the nature ofan explosion.
