Excerpt: ...It was found that much better results could be ohtained b_v introdm-ing_" all the air at one place in a tunnel, and the flues underneath the tracks were 3CCOI'dlllgl_' bricked up. It seemed that with a tender clay there was much less loss when the dry hot air, as it came from the duct, came in contact with the dryest brivk first. It could not injure these, but did absorb u little moisture, and absorbing a little more, as it passe(l on, by the time it strut-k the 1-eally tender brirk half way up the tunnel, it was Cill'I')'lllg' suflivient moisture to l'l: llll('L' its zllnsorlning pn'e'r eollsiderably.

The writer's theory has been that permanent 1-egulatio'n--to offset distance from the exhaust fan, to prevent short circuiting, etc.--should be done at the exhaust end, dampers being used over the openings from the blower duct only when for some reason it becomes necessary to close off a tunnel entirely. The disadvantages of attempting to operate dampers at both ends, and at the same time to attempt any systematic regulation, are manifest, Waste Heat Duct.
