Before attempting to discuss inside stacks, it should beremembered that the results of tests involving outside stacksshow that when other things are unchanged, the higher thestack, the better the draft; that when, through increased dia-meter of the boiler, it becomes necessary to reduce the heightot the stack, there inevitably results a loss in draft. This beingtrue of the outside stack, it becomes important to knowwhether an extension of the stack downward into the smoke-box will serve to hold up the efficiency of the draft when the Nozzle-l Stack-2 Nozzle-1 Stack-8. :: 1 A Mm I ill liii ilMl lii 5 ffiiH :::S f-- PPffffl ^ WSr^rr. iii 1 .\ i; i-» -i M
